Description

Ore powder crushing device

[0001] The present invention relates to an ore powder crushing device, and more specifically, to an ore powder crushing device that can easily crush supplied ore powder, such as graphite, into particles of a size desired by a user, easily collect and store the crushed ore powder, and easily control heat generated during the crushing process to enable continuous and stable crushing of ore powder.

[0002] Ore powder is a widely used material in various fields. For example, graphite is most commonly used as a material for pencils and mechanical pencil leads. Its electrical conductivity also makes it a valuable material for electrical conductors. Graphite is also used in heat-resistant equipment in chemical processes. Furthermore, its smooth, layered crystal structure makes it useful as an antifriction agent and lubricant, and it also serves as a mold for the production of various products.

[0003] As such, ore powder is a widely used material in various fields. Typically, ore powder is crushed into particles of a predetermined size, and then utilized through various methods depending on the intended use. To ensure smooth utilization of ore powder, it is crucial to grind it to a uniform particle size, tailored to the intended use.

[0004] In the past, in order to crush such ore powder, a device was used in which a rotating impeller connected to a motor was inserted into a tank into which a predetermined amount of ore powder was inserted, and the ore powder lumps were crushed and stirred by the rotation of the impeller, or a device was used to crush the ore powder through impact such as hammering using a device such as a hammer. However, in these cases, there is a problem in that relatively large lumps of ore powder cannot be completely crushed, and the crushed ore powder particles are not crushed evenly. In other words, when crushing ore powder by simple impact in this way, it is difficult to precisely control the particle size of the crushed particles, and there is a problem in that great difficulty occurs in controlling the microstructure during the molding process performed in the subsequent process.

[0005] In addition, conventional crushing devices have a problem in that the crushing process is inefficient because the continuous crushing process is not easy, and the process of crushing a predetermined amount of ore powder, removing the ore powder from the crushed tank, and then re-introducing the ore powder lump must be repeated.

[0006] Ore powders that are crushed in such an uneven manner have extremely limited applications, and even if they are used in some fields, there is a problem that the quality of the product deteriorates due to the low molding density caused by the uneven particles.

[0007] The present invention is intended to solve the conventional problems, and the purpose is to provide an ore powder crushing device that can easily crush supplied ore powder into particles of a desired size by a user, easily collect and store the crushed ore powder, and easily control heat generated during the crushing process to enable continuous and stable crushing of ore powder.

[0008] The purpose of the present invention is not limited thereto, and other purposes not mentioned will be clearly understood by those skilled in the art from the description below.

[0009] In order to achieve the above object of the present invention, an ore powder crushing device includes a supply unit for supplying ore powder, a crushing unit for crushing ore powder supplied through the supply unit, a power unit connected to the crushing unit and providing power for the crushing unit to crush, a collecting unit provided to be connected to the crushing unit through a collecting pipe and collecting ore powder crushed through the crushing unit, and a storage unit coupled to the collecting unit and storing the crushed ore powder collected through the collecting unit, wherein the crushing unit includes a crushing chamber providing a space for crushing the ore powder supplied from the supply unit, a door provided to be openable and closable on one surface of the crushing chamber and having a discharge hole formed through which the ore powder crushed in the crushing unit is discharged to the collecting unit, a rotating crushing plate rotatably provided on one side of the center of the crushing chamber, and a discharge plate detachably provided on the inside of the door and having a particle size adjustment hole formed on one side thereof.

[0010] At this time, further crushing irregularities may be formed on the inner surface of the crushing chamber.

[0011] In addition, the crushing chamber may further include a crushing unit that is detachably provided on the inner surface and has crushing irregularities formed on the surface.

[0012] In addition, a discharge groove is further formed on one side of the inner surface of the door to guide the crushed ore powder discharged from the particle size adjustment hole of the discharge plate to easily flow into the discharge hole of the door, and the particle size adjustment hole of the discharge plate may be formed on one side corresponding to the discharge groove.

[0013] Additionally, the discharge groove may be formed in a fan shape centered on the discharge hole.

[0014] In addition, the rotating crushing plate may include a rotating plate rotatably provided on the inside of the crushing chamber and a plurality of crushing wings provided at the tip of the rotating plate.

[0015] Additionally, at least one of the crushing blades may be formed as an amplifying blade having a relatively larger area than the crushing blade to amplify the amount of rotation of air inside the crushing chamber.

[0016] Additionally, one end of the crushing blade can be formed to be bent or curved at a predetermined angle.

[0017] Additionally, the crushing blades can be formed to be bent or curved at an angle of 100° to 160°.

[0018] In addition, the particle size control hole may be formed in an arc shape based on the center of the particle size control hole in order to obtain the crushed ore powder of uniform particle size.

[0019] In addition, the discharge plate may be provided in multiple forms so that particle size adjustment holes are formed at positions spaced apart from the center by different lengths, and may be provided replaceably with a discharge plate in which particle size adjustment holes corresponding to the particle size to be obtained in the door are formed in consideration of the particle size of the crushed ore powder.

[0020] In addition, the capturing portion is formed in a cylindrical shape, and the capturing tube can be coupled to be in contact with a tangent line of the capturing portion.

[0021] Additionally, one side of the power unit may further include a cooling unit for cooling the heat generated by the power unit or the crushing unit.

[0022] The ore powder crushing device according to the present invention has the following effects.

[0023] First, by selectively replacing the discharge plate with a discharge hole formed at a corresponding position so that the ore powder of a particle size corresponding to the intended use can be collected, the user can smoothly manufacture ore powder having a uniform particle size according to the intended use.

[0024] Second, when the particle size of the crushed ore powder changes, the discharge plate attached to the door can be replaced with a discharge plate having discharge holes formed in corresponding positions, thereby facilitating the manufacture of ore powder having various particle sizes, which has the effect of being convenient to use. In other words, by considering the particle size to be used among the discharge plates having discharge holes formed in various positions and replacing them with a discharge plate corresponding to it, the effect of being able to manufacture ore powder having various particle sizes in a single device is achieved.

[0025] Third, the crushing blades formed on the rotating crushing plate, especially the amplifying blades, promote air flow inside the chamber and amplify the flow of vortexes, thereby forming sufficient air flow without requiring additional components such as a blower fan that injects air for crushing or discharging, thereby enabling the device to be miniaturized and simplified.

[0026] Fourth, there is an effect that enables the grinding process to be performed continuously and stably by efficiently cooling the rotating shaft or rotating grinder through a cooling unit to prevent overheating due to the continuous grinding process.

[0027] Fifth, the crushed ore powder flowing into the collecting section is easily rotated the moment it flows into the collecting section due to the structural characteristics of the collecting section, and dust and ore powder are easily separated, thereby providing the effect of obtaining stably crushed ore powder.

[0028] Sixth, since the discharge plates having size-adjusting holes of different positions and sizes are formed in interchangeable manners depending on the particle size of the pulverized ore powder particles to be obtained, anyone can easily obtain pulverized ore powder particles of the desired particle size even if they are not an expert. That is, rather than the worker adjusting the position of the particle size-adjusting hole, since there are multiple discharge plates having size-adjusting holes formed according to the particle size, the worker only needs to check the particle size discharged according to the particle size-adjusting hole and replace only the discharge plate with the corresponding discharge plate, so no separate calculation is required, maximizing the convenience of use.

[0029] The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

[0044]

[0045] Composition of ore powder crushing device

[0046]

[0047] Fig. 1 is a perspective view of an ore powder crushing device according to the present invention, Fig. 2 is a perspective view showing a state in which the door of the ore powder crushing device according to the present invention is opened, and Fig. 3 is a perspective view showing a state in which the rotating crushing plate and the discharge plate of the ore powder crushing device according to the present invention are separated. As shown in Figs. 1 to 3, the ore powder crushing device (10) according to the present invention is largely composed of a supply section (100), a crushing section (200), a power section (300), a collection section (500), a storage section (600), and a dust collection section (700).

[0048] The supply unit (100) is a device that supplies the crushing target material, i.e., the ore powder lumps, to the crushing unit (200). Any device may be used as the supply unit (100) as long as it can stably, continuously, or periodically supply the crushing target material to the crushing unit (200). In one embodiment, the supply unit (100) may include a hopper (110) and a transfer unit.

[0049] The hopper (110) is a device having a shape with a narrow top and bottom, which facilitates the loading of materials to be crushed and ensures the stable supply of the loaded materials to be crushed. This hopper (110) is commonly used in the art, and a detailed description thereof will be omitted.

[0050] The transfer unit is a device that stably transfers the crushing target material supplied to the hopper (110) to the crushing unit (200). Although the crushing target material supplied from the hopper (110) may be directly supplied to the crushing unit (200), it is preferable to additionally provide a transfer unit to stably supply a certain amount of the crushing target material. As long as the crushing target material supplied from the hopper (110) can be transferred and supplied at a certain cycle, any device may be used as the transfer unit. However, it is preferable to use a transfer unit that includes a transfer screw to facilitate transfer and stably transfer the crushing target material.

[0051] Here, one side of the supply unit (100), preferably one side connected to the transfer unit, may further be provided with an air inlet for allowing external air to be introduced together with the object to be crushed supplied through the transfer unit. As a result, as external air is easily introduced into the crushing chamber (210), the flow of air and the formation of vortexes within the crushing chamber (210) facilitate the rotational crushing plate (230), thereby facilitating the crushing and movement of the object to be crushed.

[0052] The crushing unit (200) is a device that crushes the crushing target material supplied from the supply unit (100). This crushing unit (200) is composed of a crushing chamber (210) having one open side to crush the crushing target material into stable and consistent particles, a door (220) that opens and closes the open side of the crushing chamber (210), a rotating crushing plate (230) provided in the crushing chamber (210), and a discharge plate (240) detachably provided in the door (220). Each component is described in more detail as follows.

[0053] The crushing chamber (210) is a device that provides a space where the crushing target supplied from the supply unit (100) is introduced and crushed. The crushing chamber (210) is not limited in shape and size as long as it can provide a predetermined space so that the crushing target can be introduced therein and crushed, and may be configured in various shapes and sizes considering the crushing capacity, etc. However, since the crushing unit (200) according to the present invention crushes the crushing target through a rotating grinding plate (230), it is preferable that the internal space be formed as a cylindrical groove, and one side, preferably the front side, be opened. In one embodiment, the crushing chamber (210) is preferably formed in a cylindrical shape with one side open, and an inlet (211) is formed on one side of the other side corresponding to the open side, or on one side of the side wall, through which the crushing target supplied from the supply unit (100) is introduced.

[0054] The door (220) is a device that is openable and closable on one side of the crushing chamber (210) and opens and closes the crushing chamber (210). The door (220) is preferably provided to have a shape and area corresponding to the exterior of the crushing chamber (210), and is preferably provided to be easily openable and closable through a hinge connection or the like with the crushing chamber (210). At this time, a discharge hole (221), a discharge groove (222), and a coupling protrusion (223) may be formed on one side of the door (220).

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

[0056] The discharge groove (222) serves to guide the pulverized particles so that they can smoothly flow into the discharge hole (221) so that the pulverized particles can be easily discharged through the discharge hole (221). The discharge groove (222) may be formed in any shape as long as the aforementioned purpose can be achieved. However, it is preferable that it is formed in a fan shape with the discharge hole (221) as the center, and the end of the fan shape is preferably formed to a portion corresponding to the inner diameter of the pulverization chamber (210), and the forming angle and depth thereof can be formed at various angles in consideration of the pulverization capacity, etc. In addition, it is preferable that the discharge groove (222) is formed in a shape that gradually widens as it goes upwards with the discharge hole (221) as the center.

[0057] The coupling protrusion (223) is formed to protrude on one side of the inside of the door (220) so that the discharge plate (240) can be detachably coupled. The coupling protrusion (223) is formed to protrude to a predetermined length on one side of the inside of the door (220), and although the number thereof is not limited, it is preferable to form at least two or more so that the discharge plate (240) can be stably fastened in the correct position.

[0058] Fig. 4 is a rear perspective view of a rotary crusher according to the present invention. The rotary crusher (230) is a device that is connected to a power unit (300) inside a crushing chamber (210) and rotates by a rotational force transmitted from the power unit (300) to crush an object to be crushed by the rotational force. The shape and size of the rotary crusher (230) are not limited as long as it rotates inside the crushing chamber (210) and can easily crush an object to be crushed. In one embodiment, the rotary crusher (230) may be composed of a rotating plate (231) and a crushing blade (232).

[0059] The rotating plate is a device that is rotatably coupled to the inside of the crushing chamber (210) so that the rotating blades provided on one side of the rotating plate (231) can collide with the object to be crushed to crush the object to be crushed, thereby crushing the object to be crushed. At this time, the rotating plate (231) is a device that is connected to the drive shaft or transmission shaft of the power unit (300) inserted into one side of the inner center of the crushing chamber (210), preferably one side of the center of the crushing chamber (210), and rotates by the power transmitted from the power unit (300). At this time, the rotating plate (231) is provided so that it can be spaced apart from the discharge plate (240) provided on the inner side of the crushing chamber (210) and the door (220) by a predetermined distance, respectively. In addition, it is obvious that the rotating plate (231) is provided so as to have a diameter that is relatively smaller than the inner circumferential surface of the crushing chamber (210).

[0060] The crushing blades (232) are formed to protrude radially at equal intervals from the end of the rotating plate (231) and are a device for crushing objects between the leading ends of the crushing blades (232) and the inner surface of the crushing chamber (210). The number and thickness of the crushing blades (232) may be set in various ways. In addition, the crushing blades (232) may be formed to protrude inward and outward of the rotating plate (231) so that crushing can also occur between the discharge plate (240) and the inner surface of the crushing chamber (210). That is, the crushing blades (232) may be formed as a flat plate-shaped member provided on the outer surface of the rotating plate (231) so as to be inclined at a predetermined angle with respect to the rotating plate (231) at the end of the rotating plate (231), preferably perpendicularly. To this end, the rotary blade can be formed integrally by welding or the like by inserting a flat-plate-shaped rotary blade having a groove corresponding to the thickness of the rotary plate (231) into the rotary plate (231), or the aforementioned shape can be manufactured integrally by casting. In addition, the rotary blade can be formed in a form in which the width gradually increases from the center of the rotary plate (231) toward the outside.

[0061] As illustrated in FIG. 3, among the aforementioned crushing wings (232), some crushing wings (232) are formed so that the wings protruding inward have a relatively wider area than the other crushing wings (232), and such crushing wings (232) are referred to as amplifying wings (233). These amplifying wings (233) rotate and amplify the vortex of the air inside, thereby facilitating the crushing and discharge of the object to be crushed. At this time, the crushing wings (232) may be formed on all of the crushing wings (232), but preferably, they may be formed on crushing wings (232) spaced apart at equal intervals. In one embodiment, the crushing wings (232) and the amplifying wings (233) may be formed at a ratio of 2:1. That is, two crushing wings (232) and one amplifying wing (233) may be repeatedly formed. It is obvious that the formation ratio of these crushing wings (232) and amplifying wings (233) can be formed in various ways depending on the usage.

[0062] In addition, depending on the usage, one end of the crushing blade (232), preferably one end of the outer end of the rotating plate (231), may be provided to be inclined or curved at a predetermined angle along the rotational direction of the rotating plate (231). In this way, by configuring the ore powder to be crushed inside the crushing chamber (210) to be deflected through the inclined end of the crushing blade (232), the crushing performance of the ore powder to be crushed is controlled by directly hitting the crushing blade (232), and the ore powder is configured to be introduced into the crushing unit (212) more smoothly. The angle of inclination at which the end of the crushing blade (232) is bent or curved can be determined to have various inclinations in consideration of the crushing performance, crushing degree, and spheroidization performance improvement efficiency, and preferably, the inner angle is bent or curved at an angle of 90° to 179°, and more preferably, the inner angle is bent or curved at an angle of 100° to 160°.

[0063] In addition, it is preferable that the length of the crushing blade (232) has a length corresponding to the internal area of ​​the crushing chamber (210), and preferably, it is preferable that the inner surface of the crushing chamber (210), more preferably, the inner surface of the crushing unit (212), and the end of the crushing blade (232) have a length spaced apart by 1 mm to 20 mm, preferably 7 mm to 10 mm.

[0064] Fig. 5 is a perspective view of a grinding roughening unit according to the present invention. As shown in the enlarged portion of Fig. 2 and Fig. 5, a grinding roughening unit (212) may be further provided on the inside of the grinding chamber (210) to even out the grinding surface of the object to be ground. Any device may be used as the grinding roughening unit (212) as long as it forms grinding roughening (213) on the surface. In one embodiment, the grinding roughening unit (212) forms grinding roughening (213) on the inner surface of the grinding chamber (210), so that the inner surface of the grinding chamber (210) can be utilized as the grinding roughening unit (212). However, considering wear and tear due to repeated use, it is preferable to provide it as a separate member in order to reduce replacement costs and facilitate replacement. In one embodiment, the grinding irregularities unit (212) may be provided with a plurality of flat plate-shaped members having grinding irregularities (213) formed on the surface along the inner circumference of the grinding chamber (210). At this time, the grinding irregularities (213) may be formed in various shapes, but preferably, the grinding irregularities are formed in a hemispherical or semi-ellipsoidal cross-section and are formed in multiple numbers on the surface of the grinding irregularities unit (212), and more preferably, they are regularly arranged to have a predetermined width and row. When the grinding irregularities (213) are formed in a hemispherical or semi-ellipsoidal shape in this way, the surface of the grinding particles to be ground can also be ground into a spherical or ellipsoidal shape, thereby being ground into particles having a smooth surface. It is preferable that each of the grinding irregularities (213) have a diameter of Ψ6 to Ψ10, preferably Ψ7 to Ψ9, and depending on the usage, the plurality of grinding irregularities (213) may be configured so that some have the same diameter and some have different diameters.

[0065] Fig. 6 is a plan view of a discharge plate according to the present invention. The discharge plate (240) is detachably provided on the inner surface of the door (220) to discharge the crushed particles by adjusting the particle size so that the crushed particles can be discharged through the discharge hole (221) formed in the door (220) when the crushed particles are crushed to a size below a certain size. The discharge plate (240) is formed as a flat plate-shaped member having an area corresponding to the inner surface of the door (220), and a particle size adjustment hole (241) and a joining hole (242) corresponding to a fastening protrusion formed on the side surface of the door (220) are formed on one side thereof.

[0066] The particle size adjustment hole (241) is formed on one side of the discharge plate (240), preferably 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 pulverized particles to be discharged, and is formed to have a size corresponding to the discharge groove (222) depending on the position where the particle size adjustment hole (241) is formed. The particle size of the particle size adjustment hole (241) is adjusted according to the distance (a) from the center of the discharge plate (240). If the particle size adjustment hole (241) is formed at a position close to the center of the discharge plate (240), relatively large pulverized particles are discharged, and if the particle size adjustment hole is formed at a position farther from the center of the discharge plate (240), smaller pulverized particles are discharged. That is, the smaller the particle size of the pulverized particles pulverized inside the pulverization chamber (210), the lighter they become and spread out to the outside of the pulverization chamber (210). Accordingly, when the particle size control hole (241) is formed at a position close to the center of the discharge plate (240), relatively large crushed particles are discharged, and when the particle size control hole (241) is located at the outer side of the discharge plate (240), relatively small crushed particles are discharged. At this time, since the discharge groove (222) has an area that gradually increases from the center to the outer side, its area can also increase as it is formed at a position that is farther from the center to the outer side. In this way, the particle size control hole (241) can be formed at a corresponding position considering the size and weight of the crushed particles desired by the user, and when the crushed particles are to be changed, the discharge plate (240) can be replaced and used with a particle size control hole (241) corresponding to it.

[0067] In addition, the particle size control hole (241) can be formed in an arc shape with a predetermined height (b). Through this, the crushed particles discharged to the outside through the particle size control hole (241) are discharged with relatively uniform particles. At this time, the narrower the height (b) of the particle size control hole (241) formed in an arc shape, the more uniform the particle size is discharged. That is, the longer the height (b) of the particle size control hole (241), the larger the particle size distribution, and the narrower the height (b) is, the narrower the particle size distribution, so that crushed particles with more uniform particle size are discharged.

[0068] The power unit (300) is a device provided on one side of the crushing unit (200) to provide rotational force to the rotating crusher (230) included in the crushing unit (200). Any device that can transmit rotational force to the rotating crusher (230) may be used as the power unit (300), but it is preferable to use a motor (310) of a predetermined capacity. At this time, the power unit (300) composed of the motor (310) and the like is preferably provided on the rear side of the rotating crusher (230) so that the rotational axis can pass through the crushing chamber (210) and be connected to the rotational center of the rotating crusher (230) so as to have the same rotational center.

[0069] The rotary transmission shaft (350) penetrates one side of the center of the crushing chamber (210) and is coupled to the rotary crusher (230) to transmit the rotational force generated from the motor (310) to the rotary crusher (230).

[0070] At this time, depending on the usage, a cooling unit may be additionally provided on one side of the power unit (300) to suppress heat generated by friction between the rotation transmission shaft (350) and the rotation crusher (230). This cooling unit may have any configuration as long as it can cool the heat generated from the power unit (300) or the rotation crusher (230). In one embodiment, the cooling unit may be composed of a cooling tank provided to surround at least a portion of the rotation transmission shaft (350) of the power unit (300) and cooling oil filled inside the cooling tank.

[0071] Here, the cooling tank is provided to surround at least one side of the rotation transmission shaft (350) and the power unit (300), and is configured so that the rotation transmission shaft (350) can rotate while penetrating the cooling tank. In addition, the cooling oil filled inside the cooling tank is filled so that at least a part of the rotation transmission shaft (350) is submerged, so as to cool the heat transferred to the rotation transmission shaft (350), thereby cooling the temperature of the power unit (300) and the grinding unit (200). At this time, a measuring unit capable of measuring the amount of cooling oil filled inside the cooling tank may be separately provided on one side of the cooling tank. Although the present invention is described with a focus on cooling oil, it is obvious that a separate refrigerant such as cooling water or an air cooling method may be used.

[0072] Fig. 7 is a plan view showing the state of the combination of the collecting unit and the collecting tube according to the present invention, and Fig. 8 is a schematic side view showing the state of the arrangement of the collecting unit, the storage unit, and the dust collecting unit according to the present invention. The collecting unit (500) is a device that is connected to the crushing unit (200) through the collecting tube (510) and the like to collect crushed particles and dust, etc. that are crushed and discharged from the crushing unit (200). At this time, the collecting tube (510) is connected so as to connect the discharge hole (221) formed on one side of the door (220) of the crushing unit (200) and the upper side of the collecting unit (500).

[0073] In addition, the collecting unit (500) is formed in an overall cylindrical shape so that a vortex can easily be generated inside the collecting unit (500) to easily separate and store the pulverized particles and dust. At this time, it is preferable that the lower part of the collecting unit (500) be formed so that the diameter gradually narrows toward the bottom so that an air vortex can be more easily formed and the pulverized particles and dust can be easily separated. It is preferable that the portion formed to be inclined in this way be formed to be greater than the cutoff of the entire height of the collecting unit (500), and the angle of inclination can be set to various angles depending on the usage pattern.

[0074] In addition, the collecting tube (510) connected to the collecting unit (500) is preferably connected to the upper side of the collecting unit (500) so as to be in contact with the collecting unit (500) at a tangent line so as to easily form a smooth vortex when crushed particles and dust, etc. are introduced into the collecting unit (500), as shown in FIG. 8.

[0075] The storage unit (600) is a device that is detachably provided at the lower portion of the collecting unit (500) and provides a space for storing the pulverized particles separated from the dust in the collecting unit (500). This storage unit (600) is a container having a predetermined capacity, and its shape and size can be formed in various ways as long as it can be combined with the collecting unit (500) so that the stored pulverized particles do not leak out arbitrarily.

[0076] Depending on the usage, a dust collecting unit (700) may be further provided on one side of the collecting unit (500) to separate and discharge dust generated in the collecting unit (500) from the pulverized particles. The dust collecting unit (700) is a device that is provided to be coupled to the upper side of the collecting unit (500), preferably the upper end of the collecting unit (500), and is capable of sucking in foreign substances such as dust having a mass relatively smaller than that of the pulverized particles. Since this dust collecting unit (700) has a configuration similar to that of general devices for dust collection, a detailed description thereof will be omitted.

[0078] Usage patterns of ore powder crushing equipment

[0079]

[0080] The process of obtaining crushed ore powder particles by crushing ore powder using the ore powder crushing device (10) having the above-described configuration is described in more detail as follows.

[0081] Before crushing ore powder using an ore powder crushing device (10), a discharge plate (240) having a particle size adjustment hole (241) corresponding to the particle size of the crushed ore powder particles is formed in consideration of the intended purpose of use, and is connected to a door (220).

[0082] The closer the particle size adjustment hole (241) is formed to the center of the discharge plate (240), the coarser the pulverized ore powder particles are discharged, and the farther the particle size adjustment hole (241) is formed from the center of the discharge plate (240), the finer the pulverized ore powder particles are discharged. Accordingly, the discharge plate (240) in which the particle size adjustment hole (241) is formed at a position corresponding to a particle size suitable for the intended use is fastened to the door (220). In addition, even if the particle size adjustment hole (241) is formed at a similar position, the particle size error is reduced when the particle size adjustment hole (241) is narrow, and the particle size error is large when the particle size adjustment hole (241) is large. Therefore, considering these aspects, it is recommended to select a discharge plate (240) in which the position and height of the particle size adjustment hole (241) are formed appropriately for the intended use and fasten it to the door (220).

[0083] At this time, when the joining hole (242) formed in the discharge plate (240) is aligned with the fastening projection formed on the inner surface of the door (220), the particle size adjustment hole (241) formed in the discharge plate (240) is naturally aligned with the discharge groove (222) formed on the inner surface of the door (220). This is because the discharge plate (240) is formed by considering the arc length of the particle size adjustment hole (241) formed in the discharge plate (240) considering the size of the discharge groove (222). That is, when the particle size adjustment hole (241) is formed close to the center, the arc length is formed short, and when the particle size adjustment hole (241) is formed farther from the center, the arc length is formed longer.

[0084] In this way, since the particle size adjustment hole (241) of the discharge plate (240) is formed in an arc shape based on the center of the discharge plate (240) which has a center corresponding to the center of the rotating crushing plate, the crushed ore powder particles discharged through the particle size adjustment hole (241) are discharged with a uniform particle size. If the particle size adjustment hole (241) is formed in a straight line instead of an arc shape, the distance from the center of the particle size adjustment hole (241) becomes relatively shorter compared to the ends, so that the crushed ore powder particles having a relatively large particle size can be discharged in the center compared to the ends. Therefore, it is advantageous to form the particle size adjustment hole (241) in an arc shape so that the particle size adjustment hole (241) has an arc shape so that the particle sizes of all crushed ore powder particles discharged through the particle size adjustment hole (241) are discharged uniformly.

[0085] At this time, if a guide such as a comparison table listing the discharge particle sizes according to each discharge plate (240) is provided, the worker can select and use the discharge plate (240) to obtain the desired particle size through the guide, so that even if the obtained particle size changes, the worker can select and replace the discharge plate (240) that can stably obtain the crushed ore powder particles corresponding to the particle size without the help of an expert.

[0086] As described above, when the attachment of the discharge plate (240) considering the particle size of the crushed ore powder particles to the inside of the door (220) is completed, the door (220) is closed and fixed so that it is not opened arbitrarily during the crushing process. In the configuration described above, the fixing device for fixing the door (220) to the crushing chamber (210) is not described, but the configuration of the fixing device of the door (220) can use various fixing devices in addition to the fixing device illustrated in the drawing, and since such fixing devices are commonly used in the art, their description is simply omitted.

[0087] In addition, depending on the usage, a crushing irregularity unit (212) can be inserted into the inside of the crushing chamber (210). At this time, the crushing irregularity unit (212) also selectively selects the shape, size, number, etc. of the crushing irregularities (213) by considering the surface shape and surface uniformity of the ore powder particles to be crushed, and arranges the crushing irregularity unit (212) in which the crushing irregularities (213) are formed in correspondence thereto. This crushing irregularity unit (212) may be formed on only a part of the side wall surface of the crushing chamber (210) or may be formed on the entire side wall surface, but it is preferable that it be provided so that it can be arranged on the entire side wall surface of the crushing chamber (210).

[0088] In addition, after confirming that the storage unit (600) and the dust collection unit (700) are stably connected to one side of the capture unit (500), the crushing process is actually started.

[0089] First, ore powder, which is the object to be crushed, is supplied to the hopper (110) of the supply unit (100). The supply of ore powder can be carried out by a worker at regular intervals, or a conveyor or the like that automatically transports and supplies ore powder, so that a certain amount of ore powder can be automatically supplied to the hopper (110). Whether or not such automatic supply is employed can be selectively employed taking into consideration the work environment, etc.

[0090] Next, the ore powder supplied through the supply unit (100) may be supplied directly from the hopper (110) to the crushing chamber (210) depending on the combination configuration of the hopper (110), or may be supplied from the hopper (110) to the inside of the crushing chamber (210) through a transfer unit. At this time, if an air inlet is formed, external air may be introduced into the inlet (211) of the crushing chamber (210) together with the ore powder supplied from the hopper (110) through the air inlet. If an air inlet for introducing external air is provided in this way, the air flow inside the crushing chamber (210) is made smoother, thereby activating a vortex inside the crushing chamber (210), and the ore powder to be crushed can rotate more smoothly inside, thereby improving the crushing efficiency.

[0091] Next, when ore powder is supplied through the inlet (211) of the crushing chamber (210), the rotating crushing plate (230) rotates by the power transmitted from the power unit (300) and crushes the supplied ore powder. At this time, the crushing of the ore powder is performed by the ore powder passing through the gap between the crushing blade (232) protrudingly formed at the front end of the rotating crushing plate (230) and the crushing chamber (210) or the crushing roughening unit (212), and some of the ore powder is crushed by colliding with the widthwise longitudinal ends of the crushing blade (232) or the amplifying blade (233) and the inner surface of the crushing chamber (210) and the inner surface of the discharge plate (240).

[0092] At this time, the shape and surface particle size of the crushed ore powder particles can be determined by the crushing irregularities (213) of the crushing irregularities unit (212). That is, in the present invention, since the crushing irregularities unit (212) in which the crushing irregularities (213) are formed in a hemispherical or semi-ellipsoidal shape is used, the crushed ore powder particles are crushed into a spherical or ellipsoidal shape.

[0093] As described above, the crushing blade (232) and the amplifying blade (233) according to the present invention are formed so that one end portion thereof is inclined at a predetermined angle, so that when the rotating crushing plate (230) rotates, the crushing blade (232) and the amplifying blade (233) collide with the ore powder at a predetermined angle. Accordingly, the impact caused by the collision is slightly reduced, and the collided ore powder is more easily guided toward the crushing bump unit (212). Accordingly, the ore powder is prevented from being broken into an irregular shape by colliding with the crushing blade (232) and the amplifying blade (233), and the ore powder to be crushed can be crushed so that it has a more uniform shape such as a spherical or oval shape by the crushing bumps (213) of the crushing bump unit (212). In this way, since the impact amount and the induction efficiency to the crushing roughness unit (212) can be adjusted by bending or slanting the crushing blade (232) and the amplifying blade (233) at a predetermined angle, the user can selectively determine the inclination angle in various ways by considering the crushing particle size, etc.

[0094] As the rotary crusher (230) rotates in this way, a vortex is generated inside the crushing chamber (210), and the ore powder and the crushed ore powder particles rotate together due to the vortex, so that stable crushing is performed without blockage or stagnation inside the crushing chamber (210). In addition, some of the crushing wings (232) are formed as amplifying wings (233) having a relatively larger area than the crushing wings (232), so that the air flow inside the crushing chamber (210) can be amplified, thereby forming the vortex flow more smoothly. Accordingly, even without a separate ventilation fan or the like for supplying air into the crushing chamber (210), a sufficient vortex can be formed inside the crushing chamber (210), so that stable crushing can be continuously performed.

[0095] As described above, in the process of continuous crushing, ore powder that has not been sufficiently crushed does not sufficiently rise even when a vortex is generated by its weight, and remains at the bottom of the crushing chamber (210). The crushed ore powder particles, which become smaller in size and lighter in weight due to repeated crushing, sufficiently rise to the position where the particle size adjustment hole (241) of the discharge plate (240) is formed by the vortex, and are discharged through the particle size adjustment hole (241) of the discharge plate (240) and introduced into the discharge groove (222) of the door (220).

[0096] At this time, when there is heat generation in the rotating grinding plate (230) and the rotating transmission shaft (350) that rotates it due to the repetitive rotation and grinding process, the cooling unit surrounding one side of the rotating transmission shaft (350) continuously cools it, so that even if the grinding operation is performed repeatedly and continuously, the rotating transmission shaft (350) and the rotating grinding plate (230) do not generate heat above a certain temperature and can stably and continuously perform the grinding operation.

[0097] Next, the crushed ore powder particles introduced into the discharge groove (222) are discharged through the discharge hole (221) by the air discharged together with the crushed ore powder particles inside the crushing chamber (210) due to the influence of the vortex and the dust collecting force sucked in the dust collecting unit (700), and are introduced into the collecting unit (500) through the collecting pipe (510). At this time, the discharge groove (222) is formed to gradually narrow from the outside toward the center where the discharge hole (221) is formed, so that the particles are stably collected into the discharge groove (222). In addition, since the area is relatively narrower toward the discharge hole (221) compared to the outside of the discharge groove (222) where the particle size control hole (241) is formed, the pressure of the air passing through the discharge hole (221) increases due to the venturi effect, and the crushed ore powder particles are transferred to the collecting section (500) while passing through the collecting tube (510) under sufficient pressure.

[0098] Next, the crushed ore powder particles supplied to the collecting unit (500) rotate by a vortex inside the collecting unit (500), and the crushed ore powder particles and foreign substances such as dust are separated. At this time, since one end of the collecting tube (510) connected to the collecting unit (500) is connected to the outer surface of the collecting unit (500) which is formed in a cylindrical shape, the crushed ore powder particles flowing into the collecting unit (500) through the collecting tube (510) easily rotate along the inner surface of the collecting unit (500) to form a vortex while flowing into the collecting unit (500). In addition, the lower side of the collecting unit (500) is formed to be inclined so that its diameter gradually narrows downward, thereby facilitating the formation of a vortex inside the collecting unit (500).

[0099] Next, the crushed ore powder particles having a weight relatively heavier than the pressure of the dust collecting unit (700) are moved downward by the vortex formed in the collecting unit (500) and discharged to the storage unit (600), and dust having a weight smaller than the pressure of the dust collecting unit (700) is sucked into the dust collecting unit (700) and discharged separately.

[0100] When a process of crushing ore powder through the above-described process is performed and crushed ore powder particles having a different particle size or particle size distribution are required, the additional supply of ore powder through the supply unit (100) is stopped and the ore powder remaining inside the crushing chamber (210) is allowed to stand by so that all of the ore powder can be crushed and discharged.

[0101] Afterwards, open the door (220), remove the currently connected discharge plate (240), and replace the discharge plate (240) with a changed position of the particle size adjustment hole (241) or a changed height of the particle size adjustment hole (241), and then perform the process described above after installation.

[0102] Depending on the usage, the ore powder crushing devices (10) performing the aforementioned process may be arranged in parallel, and the crushed ore powder particles discharged from the collecting unit (500) of the preceding ore powder crushing device (10) may be connected to the supply unit (100) of the subsequent ore powder crushing device (10), so that the crushing process may be performed step by step to gradually have a finer particle size.
