Description

TECHNICAL FIELD

[0001] The present invention relates to a mineral powder pulverizing device, and more particularly, to a device capable of easily pulverizing a supplied mineral powder such as graphite into a particle of a size required by a user, easily capturing and storing the pulverized mineral powder, and easily controlling heat generated in a pulverizing process, thereby continuously and stably pulverizing the mineral powder. BACKGROUND

[0002] A mineral powder is a material widely used in various fields. As an example, graphite is used as a material of the most typical pencil and pencil lead, and as a raw material of a good conductor using electrical conductivity. In addition, graphite is also used as a material of a heat-resistant equipment in a chemical process. In addition, since its crystal structure is layered and the surface is smooth, it can also be used as an anti-wear agent and a lubricant, and as a mold in manufacturing various articles.

[0003] As a material widely used in various fields, a mineral powder generally needs to be pulverized into a particle having a prescribed size, and then the pulverized mineral powder is used according to a use purpose through various methods. For this reason, in order to smoothly use the mineral powder, it is important to pulverize the mineral powder to have a uniform particle size in accordance with the use purpose.

[0004] In the past, in order to pulverize such a mineral powder, a device in which an impeller connected to a motor and rotated is inserted into a tank into which a mineral powder of a specified capacity is inserted, and the mineral powder lumps are pulverized and stirred by the rotation of the impeller, or a device using a hammer or the like, and pulverizing the mineral powder by impact such as hammering, has been used. However, in this case, there are problems that a relatively large mineral powder lump cannot be completely pulverized, and the pulverized mineral powder particles are not uniform. That is, if the mineral powder is pulverized only by such a simple impact, it is difficult to accurately control the particle size of the pulverized particles, and in a subsequent molding process, great difficulty is encountered in microstructure control.

[0005] In addition, the pulverizing device of the past has a problem of low pulverizing process efficiency because it is not easy to perform a continuous pulverizing process, and a process of repeatedly pulverizing a mineral powder of a specified capacity, taking out the mineral powder from the pulverizing tank, and then again feeding the mineral powder lumps is required.

[0006] As such, the pulverized mineral powder having a non-uniform particle size is greatly limited in its use field, and even if it is used in some fields, the molding density is lowered due to the non-uniform particles, resulting in a decrease in product quality. SUMMARY

[0007] TECHNICAL PROBLEM

[0008] The present invention is aimed at solving the existing problems, and has the object of providing an ore powder crushing device that can easily crush ore powder supplied to a size required by a user, easily collect and store the crushed ore powder, and easily control heat generated in the crushing process, thereby continuously and stably crushing the ore powder.

[0009] The objects of the present invention are not limited to the above, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.

[0010] Means for solving the problem

[0011] To achieve the ore powder crushing device of the present invention as described above, the device includes a supply part for supplying ore powder, a crushing part for crushing the ore powder supplied through the supply part, a power part connected to the crushing part to provide power for crushing of the crushing part, a collection part connected to the crushing part through a collection pipe to collect the ore powder crushed through the crushing part, and a storage part combined with the collection part to store the crushed ore powder collected through the collection part. The crushing part includes a crushing chamber providing a space for crushing the ore powder supplied by the supply part, a door provided to be openably and closably on one side of the crushing chamber and forming an outlet hole for discharging the ore powder crushed by the crushing part to the collection part, and a rotating crushing disc rotatably provided on one side of the center of the crushing chamber. An outlet plate is detachably provided on the inner side of the door and forms a particle size adjustment hole on one side.

[0012] At this time, the inner circumferential surface of the crushing chamber can further form a crushing concave-convex.

[0013] In addition, a crushing concave-convex unit can be further included, which is detachably provided on the inner circumferential surface of the crushing chamber and forms a crushing concave-convex on the surface.

[0014] In addition, an outlet groove can be further formed on one side of the inner side surface of the door for guiding the crushed ore powder discharged from the particle size adjustment hole of the outlet plate to easily flow into the outlet hole of the door, and the particle size adjustment hole of the outlet plate can be formed on the side corresponding to the outlet groove.

[0015] In addition, the outlet groove can be formed in a sector shape centered on the outlet hole.

[0016] In addition, the rotating crushing disc can include a rotating disc rotatably provided on the inner side of the crushing chamber, and a plurality of crushing blades provided on the front end of the rotating disc.

[0017] In addition, at least one of the crushing blades can be composed of an enlarged blade having a relatively larger area than the crushing blades to amplify the amount of air rotation inside the crushing chamber.

[0018] Further, the tip portion of the pulverizing blade can be bent or curved at a specified angle.

[0019] Further, the pulverizing blade can be bent or curved at an angle of 100° to 160°.

[0020] Further, the particle size adjusting hole can be formed in an arc shape with the center of the particle size adjusting hole as a reference to obtain the pulverized ore powder of uniform particle size.

[0021] Further, a plurality of the discharge plates can be provided to form the particle size adjusting holes at positions having different lengths from the center, and the discharge plates can be replaced with discharge plates having particle size adjusting holes corresponding to the desired particle size formed on the door in consideration of the particle size of the pulverized ore powder.

[0022] Further, the collection portion is in a cylindrical shape, and the collection pipe can be coupled tangentially to the tangent line of the collection portion.

[0023] Further, the power portion can further include a cooling portion for cooling the power portion or the pulverizing portion which generates heat.

[0024] Effects of the Invention

[0025] The ore powder pulverizing apparatus according to the present invention has the following effects.

[0026] First, by selectively replacing the discharge plate having the discharge hole formed at a position corresponding to the purpose of use to collect the ore powder of a corresponding particle size, the user can easily manufacture the ore powder having a uniform particle size corresponding to the purpose of use.

[0027] Second, when the particle size of the pulverized ore powder is changed, the ore powder of various particle sizes can be easily manufactured by simply replacing the discharge plate attached to the door with the discharge plate having the discharge hole formed at a corresponding position, thereby having the effect of easy use. That is, the ore powder of various particle sizes can be manufactured in the same apparatus by the simple process of replacing the discharge plate corresponding to the desired particle size, without complicated operations.

[0028] Third, since the pulverizing blade, particularly the enlarged blade, formed on the rotating pulverizing disc promotes the flow of air inside the chamber and enlarges the vortex, sufficient air flow can be formed without an additional component such as a blower for injecting air for pulverization or discharge, thereby having the effect of miniaturization and simplification of the apparatus.

[0029] Fourth, the rotating shaft or the rotating pulverizing disc which is overheated due to the continuous pulverization process can be efficiently cooled by the cooling portion, thereby enabling the continuous and stable pulverization process.

[0030] Fifth, the crushed ore powder flowing into the trapping section is easily rotated at the moment of flowing in due to the structural characteristics of the trapping section, and the dust and the ore powder are easily separated, thereby obtaining stable crushed ore powder.

[0031] Sixth, since the discharge plate having different position and size of the particle size adjustment hole is used according to the particle size of the crushed ore powder to be obtained, even a non-professional person can easily obtain the crushed ore powder of the desired particle size. That is, the operator does not adjust the position of the particle size adjustment hole, but a plurality of discharge plates having different particle size adjustment holes according to the particle size adjustment hole are provided, so that the operator only needs to replace the corresponding discharge plate after confirming the particle size discharged according to the particle size adjustment hole, without performing additional calculation, thereby maximizing the convenience of use.

[0032] The effects of the present application are not limited to the above-mentioned effects, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims. BRIEF DESCRIPTION OF DRAWINGS

[0046] Structure of the ore powder pulverizing device

[0047] Figure 1 is a perspective view of a mineral powder pulverizing apparatus according to the present application, Figure 2 is a perspective view of a mineral powder pulverizing apparatus according to the present application, in which a door is in an open state, Figure 3 is a perspective view of a mineral powder pulverizing apparatus according to the present application, in which a rotating pulverizing disc and an ejection plate are in a separated state. The mineral powder pulverizing apparatus 10 according to the present application, as shown in FIG. 1, is mainly composed of a supply part 100, a pulverizing part 200, a power part 300, a trapping part 500, a storage part 600, and a dust collecting part 700. Figures 1 to 3

[0048] ​The supply unit 100 is a device for supplying the material to be pulverized, i.e., the ore powder lumps, to the pulverizing unit 200. Such a supply unit 100 can use any device capable of stably, continuously, or periodically supplying the material to be pulverized to the pulverizing unit 200. In one embodiment, the supply unit 100 can include a hopper 110 and a transfer unit.

[0049] The hopper 110 is a device in the shape of a funnel, which facilitates the introduction of the material to be pulverized and enables the introduced material to be stably supplied. Such a hopper 110 is a device commonly used in the art, and thus a detailed description thereof will be omitted.

[0050] The transfer unit is a device for stably transferring the material to be pulverized supplied to the hopper 110 to the pulverizing unit 200. Although the material to be pulverized supplied from the hopper 110 can be directly supplied to the pulverizing unit 200, in order to stably supply a predetermined amount of the material to be pulverized, it is preferable to additionally provide the transfer unit. Thus, any device can be used as the transfer unit as long as it can transfer and supply the material to be pulverized in the hopper 110 at a predetermined period. However, it is preferable to use a transfer unit including a transfer screw in order to facilitate the transfer and stably transfer the material to be pulverized.

[0051] In this case, one side of the supply unit 100, preferably the side connected to the transfer unit, can further include an air inflow unit for inflowing external air together with the material to be pulverized supplied through the transfer unit. In this manner, the external air is easily introduced into the pulverizing chamber 210, and thus the air flow and vortex are easily formed inside the pulverizing chamber 210 by the rotation of the pulverizing disc 230, and thus the pulverization and movement of the material to be pulverized can be easily performed.

[0052] The pulverizing unit 200 is a device for pulverizing the material to be pulverized supplied from the supply unit 100. Such a pulverizing unit 200 is composed of a pulverizing chamber 210 having one side open, a door 220 for opening and closing the open side of the pulverizing chamber 210, a rotating pulverizing disc 230 provided in the pulverizing chamber 210, and a discharge plate 240 detachably provided on the door 220, in order to stably pulverize the material to be pulverized into particles of a predetermined size. Each structure will be described in more detail below.

[0053] The pulverizing chamber 210 is a device that provides a space for the supply of the pulverizing material supplied from the supply part 100 to flow in and be pulverized. Such a pulverizing chamber 210 is not limited in shape and size as long as it provides a specified space for the pulverizing material to flow in and be pulverized, and can be configured in various shapes and sizes according to factors such as a pulverizing capacity. However, the pulverizing part 200 according to the present application pulverizes the pulverizing material by the rotating pulverizing disc 230 rotating, and thus the internal space is preferably configured by a cylindrical recess, and one side, preferably the front side, is in an open state. In one embodiment, the pulverizing chamber 210 is preferably a cylinder with one side open, and a flow inlet 211 for the supply of the pulverizing material supplied from the supply part 100 to flow in is formed on one side or one side of a side wall corresponding to the other side of the open side thereof.

[0054] The door 220 is a device that is provided on the open side of the pulverizing chamber 210 to be openably and closably provided, for opening and closing the pulverizing chamber 210. Such a door 220 is preferably provided to have a shape and area corresponding to the appearance of the pulverizing chamber 210, and is coupled to the pulverizing chamber 210 by a hinge coupling or the like and is easily openably and closably provided. At this time, one side of the door 220 can be formed with a discharge hole 221, a discharge groove 222, and a coupling protrusion 223.

[0055] The discharge hole 221 is formed through one side of the door 220, preferably the center side, so that the pulverized particles that have completed pulverization can be discharged to the outside.

[0056] The discharge groove 222 functions to guide the pulverized particles that have completed pulverization to smoothly flow into the discharge hole 221 so as to be easily discharged through the discharge hole 221. Such a discharge groove 222 can be configured in any shape as long as the above-mentioned purpose is achieved. However, it is preferable to be formed in a sector shape with the discharge hole 221 as the center, and the end of the sector shape is preferably extended to a portion corresponding to the inner diameter of the pulverizing chamber 210, and the angle and depth thereof can be formed in various angles according to the pulverizing capacity or the like. In addition, the discharge groove 222 is preferably formed with the discharge hole 221 as the center, and the shape thereof is gradually widened toward the upper side.

[0057] The coupling protrusion 223 is protrusively formed on the inner side of the door 220 so that the discharge plate 240 can be detachably coupled. Such a coupling protrusion 223 is protrusively formed in a specified length on the inner side of the door 220, and the number thereof is not limited, but it is preferable to be formed in at least two to secure that the discharge plate 240 can be stably fastened in a fixed position.

[0058] Figure 4is a back perspective view of the rotary pulverizing disc according to the present application. The rotary pulverizing disc 230 is a device provided at the inner side of the pulverizing chamber 210 and connected to the power unit 300, and is rotated by the rotational force transmitted from the power unit 300, and pulverizes the object to be pulverized using the rotational force. The shape and size of the rotary pulverizing disc 230 are not limited as long as it can be rotated at the inner side of the pulverizing chamber 210 and easily pulverize the object to be pulverized. In one embodiment, the rotary pulverizing disc 230 can be composed of a rotary plate 231 and a pulverizing blade 232.

[0059] The rotary disc is a device rotatably coupled at the inner side of the pulverizing chamber 210, and allows the rotary blade provided at one side of the rotary disc 231 to pulverize the object to be pulverized by colliding with the object to be pulverized. At this time, the rotary disc 231 is a device connected to the driving shaft or transmission shaft of the power unit 300 inserted at the center side of the pulverizing chamber 210, preferably inserted at the center side of the pulverizing chamber 210, and is rotated by the power transmitted from the power unit 300. At this time, the rotary disc 231 maintains a specified interval from the inner side surface of the pulverizing chamber 210 and the discharge plate 240 provided at the door 220, respectively. In addition, it is obvious that the diameter of the rotary disc 231 is relatively smaller than the diameter of the inner circumferential surface of the pulverizing chamber 210.

[0060] The pulverizing blade 232 is a device protruded radially at regular intervals at the end of the rotary disc 231, and is used to pulverize the object to be pulverized between the front end of the pulverizing blade 232 and the inner circumferential surface of the pulverizing chamber 210. The number and thickness of the pulverizing blade 232 can be variously set. In addition, the pulverizing blade 232 can be protruded at the inner side and outer side of the rotary disc 231 so that the pulverization can be performed between the discharge plate 240 and the inner side surface of the pulverizing chamber 210. That is, the pulverizing blade 232 can be composed of a flat plate-shaped member provided at the end of the rotary disc 231 at a specified angle with respect to the rotary disc 231, preferably perpendicularly to the outer circumferential surface of the rotary disc 231. For this, the rotary blade can be integrally formed with the rotary disc 231 by inserting the flat plate-shaped rotary blade into a groove corresponding to the thickness of the rotary disc 231 and welding or the like, or can be integrally formed in the aforementioned shape by casting. In addition, the rotary blade can have a shape gradually widened toward the outer side from the center direction of the rotary disc 231.

[0061] As Figure 3As shown, some of the aforementioned pulverizing blades 232 are formed in a manner that the blade area protruding to the inner side is wider than the other pulverizing blades 232, and such a pulverizing blade 232 is named as an enlarged blade 233. Such an enlarged blade 233 enlarges the vortex of the internal air by rotation, thereby easily performing pulverization and discharge of the object to be pulverized. At this time, the pulverizing blades 232 can be formed on all of the pulverizing blades 232, but are preferably formed on the pulverizing blades 232 spaced apart at equal intervals. In one embodiment, the pulverizing blades 232 and the enlarged blade 233 can be formed in a ratio of 2:1. That is, two pulverizing blades 232 and one enlarged blade 233 can be repeatedly formed. Obviously, the formation ratio of the pulverizing blades 232 and the enlarged blade 233 can be variously formed according to the use.

[0062] In addition, according to the use, the end portion side of the pulverizing blade 232, preferably the outer side direction end portion side of the rotating plate 231, can be bent or curved in a specified angle obliquely along the rotation direction of the rotating plate 231. In this way, by setting the pulverized ore powder inside the pulverizing chamber 210 to collide obliquely through the end portion of the pulverizing blade 232 obliquely formed, the pulverization performance of the ore powder directly colliding with the pulverizing blade 232 and being pulverized is adjusted, and the ore powder is more smoothly flowed into the pulverizing concave-convex unit 212. The oblique angle of the bending or curving of the end portion of the pulverizing blade 232 can be determined according to the pulverization performance, the degree of pulverization, the efficiency of the spheroidization performance, etc., and can have various degrees of inclination, and is preferably bent or curved at an inner angle of 90° to 179°, and more preferably bent or curved at an inner angle of 100° to 160°.

[0063] In addition, the length of the pulverizing blade 232 is preferably corresponding to the internal area of the pulverizing chamber 210, and preferably, the inner circumferential surface of the pulverizing chamber 210, and more preferably, the inner circumferential surface of the pulverizing concave-convex unit 212 and the end portion of the pulverizing blade 232 are maintained at a spaced length of 1 mm to 20 mm, and preferably, a spaced length of 7 mm to 10 mm.

[0064] Figure 5 is a perspective view of a pulverizing concave-convex unit according to the present application. As Figure 2 an enlarged portion of Figure 5As shown, the inside of the pulverizing chamber 210 can also be provided with a pulverizing concave-convex unit 212 for making the pulverizing surface of the object to be pulverized uniform. This pulverizing concave-convex unit 212 can use any device that forms a pulverizing concave-convex 213 on the surface. In one embodiment, the pulverizing concave-convex unit 212 can utilize the inner circumferential surface of the pulverizing chamber 210 by forming the pulverizing concave-convex 213 on the inner circumferential surface of the pulverizing chamber 210. However, in consideration of wear and the like that can occur due to repeated use, it is preferable to exist as a separate part in order to reduce replacement costs and facilitate replacement. In one embodiment, the pulverizing concave-convex unit 212 can include a plurality of flat plate-shaped parts having the pulverizing concave-convex 213 formed on the surface thereof and arranged along the inner circumferential surface of the pulverizing chamber 210. At this time, the pulverizing concave-convex 213 can be formed in various shapes, but it is preferable to form a cross-section in a semi-spherical or semi-ellipsoidal shape and form a plurality of them on the surface of the pulverizing concave-convex unit 212, and more preferably to arrange them in a regular manner having a prescribed row and column. In this way, if the pulverizing concave-convex 213 is formed in a semi-spherical or semi-ellipsoidal shape, the surface of the pulverized pulverizing particles will also be pulverized into a spherical or ellipsoidal shape, having a smooth surface. It is preferable for the pulverizing concave-convex 213 to have a diameter of φ6 to φ10, and more preferably φ7 to φ9, respectively, and a plurality of the pulverizing concave-convex 213 can have the same diameter in part and different diameters in part, according to the manner of use.

[0065] Figure 6 FIG. 10 is a plan view of the discharge plate according to the present application. The discharge plate 240 is detachably provided on the inner surface of the door 220 and controls the discharge of the pulverized pulverizing particles through the discharge hole 221 on the door 220 by adjusting the particle size when the size of the pulverized pulverizing particles reaches a prescribed standard or less. This discharge plate 240 is formed as a whole by a flat plate-shaped part having an area corresponding to the inner surface of the door 220, and a particle size adjusting hole 241 is formed on one side thereof, and a coupling hole 242 corresponding to the fastening protrusion formed on the side surface of the door 220.

[0066] The particle size adjustment hole 241 is located at one side of the discharge plate 240, and is preferably formed at a position corresponding to the discharge groove 222 of the door 220. At this time, the particle size adjustment hole 241 can be formed at various positions in consideration of the particle size of the crushed particles to be discharged, and has a size corresponding to the discharge hole 222 according to the position at which the particle size adjustment hole 241 is formed. Such a particle size adjustment hole 241 adjusts the particles according to the distance (a) from the center of the discharge plate 240. When the particle size adjustment hole 241 is formed at a position close to the center of the discharge plate 240, relatively large crushed particles are discharged; when the particle size adjustment hole 241 is formed at a position away from the center of the discharge plate 240, smaller crushed particles are discharged. That is, the crushed particles crushed inside the crushing chamber 210, the smaller the size of the particles, the lighter the weight, and are diffused to the outside of the crushing chamber 210. Therefore, when the particle size adjustment hole 241 is formed at a position close to the center of the discharge plate 240, relatively large crushed particles are discharged; when the particle size adjustment hole 241 is located at the outside of the discharge plate 240, relatively small crushed particles are discharged. At this time, since the discharge groove 222 gradually increases in area from the center to the outside, the particle size adjustment hole 241 can also increase in area when formed at a position away from the center to the outside in correspondence thereto. In this way, the particle size adjustment hole 241 can be formed at a corresponding position in consideration of the size and weight of the crushed particles desired by the user, and if it is necessary to change the crushed particles, the discharge plate 240 formed with the particle size adjustment hole 241 corresponding thereto can be used by being replaced.

[0067] Further, the particle size adjustment hole 241 can be formed in an arc shape having a specified height (b). In this way, the crushed particles discharged to the outside through the particle size adjustment hole 241 have a relatively uniform particle size and are discharged. At this time, the narrower the length of the height (b) of the particle size adjustment hole 241 formed in an arc shape, the more uniform the particle size of the crushed particles discharged. That is, the longer the height (b) of the particle size adjustment hole 241, the greater the particle size distribution, and the narrower the height (b), the narrower the particle size distribution, and the crushed particles discharged have a more uniform particle size.

[0068] The power unit 300 is a device provided at one side of the crushing unit 200 to provide a rotating force to the rotating crushing disc 230 included in the crushing unit 200. Such a power unit 300 can use any device as long as it can transmit a rotating force to the rotating crushing disc 230, but it is preferable to use a motor 310 of a specified capacity. At this time, the power unit 300 constituted by the motor 310 or the like is preferably provided at a rear side of the rotating crushing disc 230 so that its rotating shaft passes through the crushing chamber 210 and is connected to the rotating center of the rotating crushing disc 230, thereby having the same rotating center.

[0069] The rotating transmission shaft 350 passes through the center side of the crushing chamber 210 and is combined with the rotating crushing disc 230, thereby functioning to transmit the rotating force generated by the motor 310 to the rotating crushing disc 230.

[0070] At this time, according to the use, a cooling part for suppressing the heat generated by the friction of the rotation transmission shaft 350 and the rotation pulverizing disc 230 can be additionally provided on one side of the power part 300. This cooling part can be any structure capable of cooling the heat generated by the power part 300 or the rotation pulverizing disc 230. As an embodiment, the cooling part can be composed of a cooling tank surrounding at least a part of the rotation transmission shaft 350 of the power part 300 and cooling oil filled in the cooling tank.

[0071] The cooling tank surrounds at least one side of the rotation transmission shaft 350 and the power part 300, and the rotation transmission shaft 350 can rotate through the cooling tank. The cooling oil filled in the cooling tank is filled in an amount sufficient to immerse at least a part of the rotation transmission shaft 350, thereby cooling the heat transferred to the rotation transmission shaft 350 and reducing the temperature of the power part 300 and the pulverizing part 200. At this time, one side of the cooling tank can be additionally provided with a measuring part for measuring the filling amount of the cooling oil filled in the cooling tank. The present application is described with the cooling oil as the center, but it is obvious that an additional coolant such as cooling water or an air cooling method can be used.

[0072] Figure 7 is a top view of the combined state of the trapping part and the trapping pipe according to the present application, Figure 8 is a simple side view of the configuration state of the trapping part, the storage part, and the dust collecting part according to the present application. The trapping part 500 is connected to the pulverizing part 200 through the trapping pipe 510 or the like, and is used to trap the pulverized particles and dust or the like discharged from the pulverizing part 200. At this time, the trapping pipe 510 connects the discharge hole 221 formed on the door 220 side of the pulverizing part 200 and the upper side of the trapping part 500.

[0073] In addition, in order to easily separate and store the pulverized particles and the dust, the trapping part 500 is overall cylindrical, so that the vortex flow is easily generated inside the trapping part 500. At this time, the lower side of the trapping part 500 is preferably gradually tapered in diameter, so that the air vortex flow is more easily formed, thereby easily separating the pulverized particles and the dust. The portion formed like this is preferably more than half of the total height of the trapping part 500, and the inclination angle thereof can be set to various angles according to the use.

[0074] In addition, in order to easily form a smooth vortex flow while the pulverized particles and the dust or the like are introduced into the trapping part 500, the trapping pipe 510 connected to the trapping part 500 is preferably combined with the upper side of the trapping part 500 as shown in Figure 8 , and in particular, is tangentially combined with the trapping part 500.

[0075] The storage part 600 is detachably provided at the lower portion of the collection part 500, and provides a space for storing the crushed particles separated from the dust in the collection part 500. The storage part 600 is a container having a specified capacity, and its shape and size can be variously formed as long as it is combined with the collection part 500 to prevent the stored crushed particles from being arbitrarily leaked.

[0076] According to the use, in order to separate and discharge the dust generated from the collection part 500 from the crushed particles, a dust collecting part 700 can be further provided at one side of the collection part 500. The dust collecting part 700 is provided at one side of the upper portion of the collection part 500, and is preferably combined with the upper end of the collection part 500, and is a device for sucking the impurities such as dust having a relatively small mass compared to the crushed particles. Since the structure of the dust collecting part 700 is similar to that of a conventional device for collecting dust, a detailed description thereof will be omitted.

[0077] Usage of the ore powder pulverizing device

[0078] Hereinafter, a process of crushing ore powder to obtain crushed ore powder particles using the ore powder crushing device 10 having the foregoing structure will be described in more detail.

[0079] Before crushing ore powder using the ore powder crushing device 10, the discharge plate 240 having the particle size adjustment holes 241 corresponding to the particle size of the crushed ore powder particles according to the purpose of use is combined with the door 220.

[0080] The closer the particle size adjustment hole 241 is to the center of the discharge plate 240, the coarser the particle size of the crushed ore powder particles discharged; the farther the particle size adjustment hole 241 is from the center of the discharge plate 240, the finer the particle size of the crushed ore powder particles discharged. Therefore, the discharge plate 240 having the particle size adjustment holes 241 formed at positions corresponding to the particle sizes suitable for the purpose of use is fastened to the door 220. In addition, the positions of the particle size adjustment holes 241 are formed similarly, and if the height of the particle size adjustment hole 241 is narrow, the particle size error is reduced, and if the height of the particle size adjustment hole 241 is large, the particle size error is increased, and thus the discharge plate 240 having the particle size adjustment holes 241 formed at positions and having a height suitable for the purpose of use is preferably selected and fastened to the door 220.

[0081] At this time, when the coupling hole 242 formed in the discharge plate 240 is aligned with and coupled to the fastening protrusion formed on the inner side surface of the door 220, the particle size adjustment hole 241 formed in the discharge plate 240 is naturally coupled to the discharge groove 222 formed on the inner side of the door 220 in alignment. This is because, when the discharge plate 240 is formed, the arc length of the particle size adjustment hole 241 formed in the discharge plate 240 is considered according to the size of the discharge groove 222. That is, when the particle size adjustment hole 241 is formed at a position close to the center, the arc length is short, and when the particle size adjustment hole 241 is formed at a position far from the center, the arc length is long.

[0082] Therefore, since the particle size adjusting hole 241 of the discharge plate 240 is formed in an arc shape with the center of the discharge plate 240 corresponding to the center of the rotating pulverizing disc as a reference, the pulverized ore powder particles discharged through the particle size adjusting hole 241 have uniform particle size. If the particle size adjusting hole 241 is not arc-shaped but linear, the central portion of the particle size adjusting hole 241 is relatively short in distance from the center compared to the both ends, and thus the pulverized ore powder particles of a coarser particle size than the both end portions can be discharged in the central portion. Therefore, the particle size adjusting hole 241 is formed in an arc shape, which is advantageous in ensuring that all of the pulverized ore powder particles discharged through the particle size adjusting hole 241 have uniform particle size.

[0083] At this time, if a guide indicating the particle size and the like of the pulverized ore powder particles discharged through each of the discharge plates 240 is provided at the same time, the operator can select and use the discharge plate 240 for obtaining the desired particle size through the guide, and even if the obtained particle size needs to be changed, the operator can stably select and replace the discharge plate 240 for the pulverized ore powder particles corresponding to the particle size without the help of an expert and use it.

[0084] As described above, when the discharge plate 240 considering the particle size of the pulverized ore powder particles is coupled to the inner side of the door 220, the door 220 is closed and fixed after the coupling is completed, to prevent it from being opened at will during the pulverizing process. In the foregoing structure, although the fixing device for fixing the door 220 to the pulverizing chamber 210 is not described, various fixing devices other than the illustrated fixing device can be used, and such fixing devices are commonly used in the art, and thus the description thereof is omitted herein.

[0085] In addition, the pulverizing concave-convex unit 212 can be inserted into the inner side of the pulverizing chamber 210 according to the use mode. At this time, the pulverizing concave-convex unit 212 also needs to consider the surface shape and the surface uniformity of the pulverized ore powder particles and the like, and the shape, size, and number of the pulverizing concave-convex 213 are selected and the pulverizing concave-convex unit 212 formed with the pulverizing concave-convex 213 corresponding thereto is disposed. Such a pulverizing concave-convex unit 212 can be formed only on a portion of the side wall surface of the pulverizing chamber 210 or can be integrally formed, but is preferably disposed integrally on the side wall surface of the pulverizing chamber 210.

[0086] In addition, after it is confirmed that the storage portion 600 and the dust collecting portion 700 are stably coupled to one side of the trapping portion 500, the pulverizing process is substantially started.

[0087] First, the ore powder to be pulverized is supplied to the hopper 110 of the supply portion 100. The supply of such ore powder can be performed by the operator at a prescribed period, or a prescribed amount of ore powder can be automatically supplied to the hopper 110 by a conveyor belt or the like that automatically transports and supplies the ore powder. Such an automatic supply method can be selectively used according to factors such as the working environment.

[0088] Next, the ore powder supplied through the supply unit 100 can be directly supplied to the inside of the pulverizing chamber 210 from the hopper 110 according to the coupling structure of the hopper 110, or can be supplied to the inside of the pulverizing chamber 210 from the hopper 110 through the transfer unit. At this time, if the air inflow portion is formed, the external air can flow into the inflow port 211 of the pulverizing chamber 210 together with the ore powder supplied from the hopper 110 through the air inflow portion. If the air inflow portion through which the external air flows is provided, the air flow inside the pulverizing chamber 210 can be more smoothly, the vortex inside the pulverizing chamber 210 can be activated, and the pulverized ore powder can be more smoothly rotated inside, so that the pulverization efficiency can be improved.

[0089] Next, when the ore powder is supplied through the inflow port 211 of the pulverizing chamber 210, the rotary pulverizing disc 230 rotated by the power transmitted from the power unit 300 rotates and pulverizes the supplied ore powder. At this time, the ore powder is pulverized by passing through the gap between the pulverizing blades 232 protruding from the front end of the rotary pulverizing disc 230 and the pulverizing chamber 210 or the pulverizing concave-convex unit 212, and part of the ore powder is pulverized by colliding with the width direction end of the pulverizing blades 232 or the amplification blades 233 and the inner side surface of the pulverizing chamber 210 and the inner side surface of the discharge plate 240.

[0090] At this time, the surface shape and surface particle size of the pulverized ore powder particles can be determined by the pulverizing concave-convex 213 of the pulverizing concave-convex unit 212. That is, in the present application, since the pulverizing concave-convex unit 212 having the semi-spherical or semi-elliptical pulverizing concave-convex 213 is used, the pulverized ore powder particles are pulverized into spherical or elliptical shapes.

[0091] The pulverizing blades 232 and the amplification blades 233 according to the present application, as described above, are formed to be inclined at a predetermined angle at the end portion side, so that the collision with the ore powder when the rotary pulverizing disc 230 rotates is inclined at a predetermined angle. Therefore, the impact amount generated by the collision is slightly reduced, and the ore powder after the collision is more easily guided in the direction of the pulverizing concave-convex unit 212. In this way, it is possible to prevent the ore powder from being irregularly broken by the collision with the pulverizing blades 232 and the amplification blades 233, and the pulverized ore powder can be pulverized into more uniform spherical or elliptical shapes by the pulverizing concave-convex 213 of the pulverizing concave-convex unit 212. As such, the pulverizing blades 232 and the amplification blades 233 are bent or curved at a predetermined angle, so that the impact amount and the guiding efficiency to the pulverizing concave-convex unit 212 can be adjusted, and thus a user can selectively determine various inclination angles according to factors such as the pulverization particle size.

[0092] Thus, as the rotary pulverizing disc 230 rotates, a vortex is generated inside the pulverizing chamber 210, and the vortex carries the ore powder and the pulverized ore powder particles to rotate, so that no clogging or stagnation occurs inside the pulverizing chamber 210, and the pulverization is stably performed. In addition, the enlarged blades 233 formed by some of the pulverizing blades 232 having a wider area than the pulverizing blades 232 can amplify the air flow inside the pulverizing chamber 210, so that the vortex is more smoothly generated. Thus, even without an additional device such as a blower for supplying air to the inside of the pulverizing chamber 210, a sufficient vortex can be generated inside the pulverizing chamber 210, so that the pulverization is continuously and stably performed.

[0093] As described above, in the continuous pulverization process, if the ore powder that is not sufficiently pulverized due to its weight does not sufficiently float even if the vortex is generated, and remains below the pulverizing chamber 210; through repeated pulverization, the pulverized ore powder particles having a small particle size and a light weight sufficiently float with the vortex, reach the position where the particle size adjustment holes 241 of the discharge plate 240 are formed, and are discharged through the particle size adjustment holes 241 of the discharge plate 240, and flow into the discharge groove 222 of the door 220.

[0094] At this time, if the rotary pulverizing disc 230 and the rotary transmission shaft 350 rotating the same are heated due to repeated rotation and pulverization processes, the cooling portion surrounding the rotary transmission shaft 350 continuously cools the same, so that even if the pulverization operation is repeatedly and continuously performed, the rotary transmission shaft 350 and the rotary pulverizing disc 230 are not heated beyond a predetermined temperature, and the pulverization operation can be continuously and stably performed.

[0095] Next, the pulverized ore powder particles flowing into the discharge groove 222 are discharged through the discharge hole 221 under the influence of the vortex, the air discharged together with the pulverized ore powder particles inside the pulverizing chamber 210, and the dust collection force of the dust collection portion 700, and flow into the collection portion 500 through the collection pipe 510. At this time, the discharge groove 222 is gradually narrowed from the outside toward the center where the discharge hole 221 is formed, so that the pulverized ore powder particles are stably converged into the discharge groove 222. In addition, the area in the direction of the discharge hole 221 is relatively narrow compared to the outside of the discharge groove 222 where the particle size adjustment holes 241 are formed, so that the air pressure passing through the discharge hole 221 is increased by the Venturi effect, and the pulverized ore powder particles receive sufficient pressure to pass through the collection pipe 510 and be transferred to the collection portion 500.

[0096] Next, the crushed ore powder particles supplied to the trapping section 500 also rotate by vortex inside the trapping section 500, thereby separating the crushed ore powder particles and foreign matters such as dust. At this time, one end of the trapping pipe 510 connected to the trapping section 500 is combined in a tangential manner to the outer circumferential surface of the cylindrical trapping section 500, so that the crushed ore powder particles flowing into the trapping section 500 through the trapping pipe 510 are easily rotated along the inner circumferential surface of the trapping section 500 and form a vortex while flowing into the trapping section 500. In addition, the lower side of the trapping section 500 is tapered in a downward direction with a gradually narrowing diameter, so that the vortex is more easily formed inside the trapping section 500.

[0097] Next, the crushed ore powder particles having a relatively higher dust collection pressure than the dust collection section 700 are moved in a downward direction by the vortex formed in the trapping section 500 and discharged to the storage section 600, and the dust and the like having a lower dust collection pressure than the dust collection section 700 are sucked into the dust collection section 700 and discharged separately.

[0098] Through the above-described process, in the process of crushing the ore powder, if crushed ore powder particles having different particle sizes or different particle size distributions are required, the additional supply of the ore powder through the supply section 100 is stopped, and the process waits until the ore powder remaining inside the crushing chamber 210 is completely crushed and discharged.

[0099] After that, the door 220 is opened, the currently combined discharge plate 240 is removed, and a discharge plate 240 having a configuration position of the particle size adjustment hole 241 changed or a height of the particle size adjustment hole 241 changed is installed, and after that, the above-described process can be performed.

[0100] According to the use mode, the ore powder crushing device 10 performing the above-described process can be arranged in parallel, and the crushed ore powder particles discharged from the trapping section 500 of the preceding ore powder crushing device 10 are connected to the supply section 100 of the subsequent ore powder crushing device 10, so that the crushing process can be performed in stages to gradually obtain finer particle sizes.

[0101] As described above, it is understood by those skilled in the art to which the present application pertains that the present application can be implemented in other specific forms without changing the technical idea or essential characteristics thereof. Therefore, the described embodiments should be understood as exemplary in all aspects, not as limiting.
