Description

[0002] Ball mills are widely used in mining, building materials, refractory materials, glass and ceramics industries as the main equipment for crushing operations. However, in the actual working process, a certain amount of ore raw materials and crushing media are filled inside the ball mill, but due to the uneven particle size distribution of the ore in the axial direction, the degree of wear of the crushing media is different, which in turn affects its crushing efficiency. At the same time, when the crushing media crushes the ore, fine particles will be produced. These particles are easy to adhere to the surface of the crushing media, weakening its impact force on the ore, thereby further reducing the crushing efficiency. In addition, since the movement trajectory of the crushing media in the crushing chamber is parabolic, and the ore particles are lighter, the circulation path of the crushing media and the ore does not completely overlap. The crushing medium covers a smaller range, while the ore covers a larger range, which not only reduces the effective utilization rate of the crushing chamber, but also reduces the energy utilization rate of the crushing media.

[0023] like Figures 1 to 5 As shown, an embodiment of the present invention provides an ore raw material crushing system for refractory material processing, which includes a bracket 110, a crushing barrel 120, a positioning frame 140 and a receiving member.

[0024] The bracket 110 can be placed on the ground. Two support rods are arranged above the bracket 110 . The two support rods are both arranged vertically. The two support rods are arranged on the bracket 110 at intervals on the left and right sides.

[0025] The axis of the crushing barrel 120 is arranged horizontally, and the axis direction of the crushing barrel 120 is the same as the direction of the line between the two support rods. The crushing barrel 120 can be mounted on the two support rods. The crushing barrel 120 has a crushing chamber inside. The two ends of the axis of the crushing barrel 120 are respectively provided with a feed port and a discharge port connecting the internal space and the external environment. The crushing barrel 120 can be arranged on the bracket 110 so as to rotate around its own axis. In a specific arrangement, a driving motor 130 is arranged on the bracket 110, and a driving ring is fixedly arranged at the end of the crushing barrel 120. The driving ring is arranged coaxially with the crushing barrel 120, and the driving ring is rotatably connected with the support rods. An active ring is arranged on the power output shaft of the driving motor 130, and tooth grooves are arranged on the outer side walls of the active ring and the driving ring. The active ring is meshed and connected with the driving ring, and the driving motor 130 can drive the crushing barrel 120 to rotate through the active ring and the driving ring.

[0026] The positioning frame 140 includes two long rods and two short rods, the two long rods are parallel to each other, the two short rods are parallel to each other, each long rod is vertically arranged with a short rod, and the two long rods and the two short rods form a rectangular frame structure. A connecting member is arranged on the bracket 110, and the connecting member can horizontally arrange the positioning frame 140 inside the crushing tube 120. In a specific arrangement, the connecting member includes a first connecting rod and a second connecting rod, the first connecting rod and the second connecting rod are coaxially arranged, and the first connecting rod and the second connecting rod are both fixedly connected to the two short rods of the positioning frame 140, the first connecting rod is fixedly connected to a supporting rod, and the second connecting rod is fixedly connected to another supporting rod. Under the action of the first connecting rod and the second connecting rod, the positioning frame 140 is fixed inside the crushing tube 120, and the positioning frame 140 is in a horizontal state by adjusting the position of the positioning frame 140, and the horizontal plane where the positioning frame 140 is located is coplanar with the axis of the crushing tube 120.

[0027] The receiving member is fixedly connected to the positioning frame 140, and the receiving member has a first receiving portion and a second receiving portion. The first receiving portion is used to receive the pulverizing medium when the pulverizing barrel 120 rotates, and the first receiving portion can provide directional guidance to the received pulverizing medium. When the pulverizing barrel 120 rotates, the pulverizing barrel 120 can provide a certain kinetic energy to the pulverizing medium and the ore raw material. When the pulverizing medium rolls in the pulverizing barrel 120, part of the pulverizing medium can be received by the first receiving portion. Under the directional guidance of the first receiving portion, the position of part of the pulverizing medium in the axial direction of the pulverizing barrel 120 is adjusted, so that the wear degree of the pulverizing medium inside the pulverizing barrel 120 is uniform. Further, if the pulverizing medium cannot be adjusted in the axial direction of the pulverizing barrel 120, the wear degree of the pulverizing medium at the position close to the feed port of the pulverizing barrel 120 is relatively large. The first receiving portion is used to directional guide part of the pulverizing medium, so that the wear degree of the pulverizing medium inside the pulverizing barrel 120 is uniform. The second receiving portion is used to receive part of the ore raw material when the crushing cylinder 120 rotates, and the first receiving portion can squeeze and crush part of the ore raw material received by the second receiving portion when guiding the crushing medium. Specifically, in conventional ore raw material crushing, the impact of the crushing medium on the ore raw material is completed during the free fall of the crushing medium, wherein the impact area of ​​the crushing medium on the ore raw material is limited. By setting the second receiving portion, the impact area of ​​the crushing medium on the ore raw material is increased, thereby increasing the crushing effect and crushing efficiency of the ore raw material. In one embodiment, the crushing medium is a steel ball.

[0028] The ore raw material crushing system for refractory material processing of the present invention, when crushing the ore raw material, the ore raw material to be crushed is put into the crushing cylinder 120, and at the same time, the crushing medium is put into the crushing cylinder 120. When the crushing cylinder 120 rotates, the crushing cylinder 120 can give the crushing medium and the ore raw material a power during the rotation process. Through the impact of the crushing medium on the ore raw material, the crushing medium gradually crushes the ore raw material. By setting a positioning frame 140 inside the crushing cylinder 120, the positioning frame 140 remains in a stationary state when the crushing cylinder 120 rotates, and the positioning frame 140 is The first receiving part can receive part of the pulverizing medium, and the first receiving part can provide directional guidance to the pulverizing medium received, so that the pulverizing medium can change its position in the axial direction inside the pulverizing barrel 120; the second receiving part can receive part of the ore raw materials, and when the first receiving part provides directional guidance to the pulverizing medium received, the pulverizing medium can impact the ore raw materials received by the second receiving part, so that the range of the pulverizing medium impacting the ore raw materials inside the pulverizing barrel 120 is increased, and at the same time, the space utilization rate inside the pulverizing barrel 120 is increased, thereby increasing the pulverizing efficiency of the ore raw materials.

[0029] In one embodiment, the receiving part further includes a cleaning ring 150, which can clean the outer wall of the pulverizing medium received by the first receiving part. Specifically, when the pulverizing medium impacts the ore raw material, the powder of the ore raw material is easily adsorbed on the outer peripheral wall of the pulverizing medium, and the powder of the ore raw material can form a loose buffer film on the outer peripheral wall of the pulverizing medium. If the powder of the ore raw material on the outer peripheral wall of the pulverizing medium is not cleaned, it is easy to reduce the impact effect of the pulverizing medium on the ore raw material. By arranging the cleaning ring 150 on the first receiving part, part of the pulverizing medium received by the first receiving part can be cleaned, and as the pulverizing barrel 120 continues to rotate, the ore raw material powder attached to the surface of the pulverizing medium can be cleaned in time.

[0030] In one of the embodiments, the receiving part further includes an energy storage part, wherein the energy storage part refers to the energy storage part that can absorb energy when impacted by external force, and can release energy when it needs to release energy. The energy storage part is arranged at the end of the first receiving part, and when the pulverizing medium is about to separate from the first receiving part, the kinetic energy of the pulverizing medium is absorbed by the energy storage part, and when the pulverizing medium received by the first receiving part completely separates from the first receiving part, the energy storage part releases energy to directional push the pulverizing medium, and after the pulverizing medium is pushed, the pulverizing medium can still impact the ore raw material at the bottom of the pulverizing barrel 120 during the falling process. Furthermore, the directional push of the pulverizing medium when the energy storage part releases energy refers to the energy storage part pushing the pulverizing medium downward, thereby ensuring that the effect of the pulverizing medium impacting the ore raw material during the falling process remains unchanged.

[0031] In one embodiment, a plurality of first receiving parts are provided, and the plurality of first receiving parts are arranged at intervals along the axis direction of the crushing cylinder 120. When the crushing cylinder 120 rotates, the ore raw material and the crushing medium are subjected to a certain centrifugal force, and the ore raw material and the crushing medium can be lifted up at the same time when the crushing cylinder 120 rotates. Under the gravity of the ore raw material and the crushing medium, the ore raw material and the crushing medium can be separated from the inner wall of the crushing cylinder 120 for free fall. By providing a plurality of first receiving parts, a large amount of crushing media can be received by the first receiving parts. The first receiving part includes a receiving platform and a guiding platform. The receiving platform is used to receive part of the crushing medium when the crushing cylinder 120 rotates. The guiding platform can guide the crushing medium falling on the receiving platform toward the two end directions of the crushing cylinder 120. In a specific setting, the receiving platform mainly receives the crushing medium. When the ore raw material falls on the receiving platform, the ore raw material can automatically detach from the receiving platform. Since the volume of the crushing medium conventionally set is larger than the volume of the ore raw material, the receiving platform can only receive the crushing medium. The guiding platform is connected to the receiving platform, and the pulverizing medium entering the receiving platform can automatically enter the guiding platform. The guiding platform can guide the pulverizing medium toward the two end directions of the pulverizing cylinder 120, thereby adjusting the position of the pulverizing medium in the axial direction of the pulverizing cylinder 120, thereby ensuring that the multiple pulverizing media inside the pulverizing cylinder 120 are evenly worn.

[0032] In one embodiment, the receiving platform includes a plurality of receiving rods 210, which are arranged at intervals, and are all fixedly connected to the long rod of the positioning frame 140. The gap between any two adjacent receiving rods 210 is smaller than the diameter of the crushing medium. By setting the gap between two adjacent receiving rods 210, it is ensured that when the crushing medium falls on the receiving rods 210, the crushing medium will not escape from the receiving platform from the gap between the receiving rods 210. A first preset angle is set between each receiving rod 210 and the horizontal plane. In a specific setting, after the receiving rod 210 is tilted, the crushing medium falling on the receiving platform will roll freely, thereby preventing the crushing medium from colliding with the crushing medium already on the receiving platform when entering the receiving platform. At the same time, the tilted receiving rod 210 can give the crushing medium initial kinetic energy, ensuring that the crushing medium can smoothly avoid the crushing medium that enters the receiving platform later.

[0033] In one embodiment, the guide platform includes a plurality of first guide rods 220 and a plurality of second guide rods 230, and the plurality of first guide rods 220 and the plurality of second guide rods 230 are all bent, wherein the first guide rod 220 and the second guide rod 230 can be divided into two sections, and the two sections of the first guide rod 220 and the second guide rod 230 are smoothly connected, one section of the first guide rod 220 and the second guide rod 230 is arranged in the axial direction of the crushing barrel 120, and the other section of the first guide rod 220 and the second guide rod 230 is used to connect the receiving rod 210, so that the crushing medium on the receiving platform can contact the plurality of first guide rods 220 or the plurality of second guide rods 230. A plurality of first guide rods 220 can form a first arc-shaped groove with an opening facing upward, one end of the first arc-shaped groove is connected to a receiving platform formed by a plurality of receiving rods 210, and the other end of the first arc-shaped groove is arranged at the axis of the crushing cylinder 120, one end of the crushing cylinder 120 is arranged as a feed port, and the other end of the crushing cylinder 120 is arranged as a discharge port. The other end of the first arc-shaped groove is in a position facing the feed port of the crushing cylinder 120. After the crushing medium enters the receiving platform, the crushing medium can enter the first arc-shaped groove formed by the plurality of first guide rods 220, and under the guidance of the first arc-shaped groove, the crushing medium can move in the axial direction of the crushing cylinder 120. A plurality of second guide rods 230 can enclose a second arc groove with an opening facing upward, one end of the second arc groove is connected to a receiving platform formed by a plurality of receiving rods 210, and the other end of the second arc groove is arranged at the axis of the crushing cylinder 120, and the other end of the second arc groove is in a position facing the discharge port of the crushing cylinder 120. After the crushing medium enters the receiving platform, the crushing medium can enter the second arc groove formed by the plurality of second guide rods 230, and under the guidance of the second arc groove, the crushing medium can move in the axial direction of the crushing cylinder 120. The ends of the first guide rod 220 and the second guide rod 230 away from the receiving rod 210 are both provided with energy storage parts. It is easy to understand that when the crushing medium is out of contact with the first guide rod 220 or the second guide rod 230, the energy storage parts can both push the crushing medium in a directional manner.

[0034] In one embodiment, the second receiving part includes a receiving arc plate 240, which is arranged between two adjacent first receiving parts. The receiving arc plate 240 has an arc side and a straight side. The straight side of the receiving arc plate 240 is fixedly connected to the edge of the first arc groove in one of the first receiving parts, and the other straight side of the receiving arc plate 240 is fixedly connected to the edge of the second arc groove in the adjacent first receiving part. The receiving arc plate 240 is arranged at the axis of the crushing barrel 120, and the ore raw material can be received by the receiving arc plate 240. When the ore raw material falls on the receiving arc plate 240, when one of the crushing media slides along the first arc groove of the first receiving part, and when the other crushing medium slides along the second arc groove of the adjacent first receiving part, the two crushing media have relative movement, and the two crushing media can squeeze the ore raw material falling on the receiving arc plate 240, thereby achieving further crushing of the ore raw material.

[0035] In one embodiment, a plurality of hollow grooves 241 are provided on the receiving arc plate 240. After the ore raw materials falling on the receiving arc plate 240 are squeezed by two crushing media, the ore raw materials may be broken. The broken ore raw materials can be separated from the receiving arc plate 240 through the hollow grooves 241. As the crushing barrel 120 rotates, the ore raw materials not on the receiving arc plate 240 can impact the ore raw materials on the receiving arc plate 240, so that the ore raw materials on the receiving arc plate 240 can be separated from the receiving arc plate 240, making it easier for other ore raw materials to fall on the receiving arc plate 240.

[0036] In one embodiment, the energy storage part includes a mounting frame 310, a force storage spring 320 and an extrusion plate 330. The mounting frame 310 is fixedly connected to the end of the first guide rod 220 or the second guide rod 230 away from the receiving rod 210. The mounting frame 310 does not affect the sliding of the crushing medium in the first arc groove or the second arc groove. The force storage spring 320 is vertically arranged, the upper end of the force storage spring 320 is fixedly connected to the mounting frame 310, and the extrusion plate 330 is fixedly connected to the lower end of the force storage spring 320. When the pulverizing medium is separated from the first arc groove or the second arc groove, the pulverizing medium can squeeze the force storage spring 320 through the extrusion plate 330. In the process of the pulverizing medium being separated from the first arc groove or the second arc groove, the kinetic energy of the pulverizing medium sliding along the first arc groove or the second arc groove is converted into the elastic potential energy of the force storage spring 320. When the pulverizing medium is completely separated from the first arc groove and the second arc groove, the elastic potential energy of the force storage spring 320 is released, and the force storage spring 320 pushes the pulverizing medium downward through the extrusion plate 330, so that the pulverizing medium has the energy to impact the ore raw material downward.

[0037] In one embodiment, the cleaning ring 150 is fixedly mounted on the mounting frame 310, and a cleaning brush is disposed on the inner side wall of the cleaning ring 150. Specifically, the cleaning ring 150 does not hinder the sliding of the crushing medium in the first arc groove or the second arc groove, and the cleaning brush on the cleaning ring 150 is replaceable. When the crushing medium passes through the cleaning ring 150, the cleaning brush disposed on the cleaning ring 150 can clean the outer peripheral wall of the crushing medium.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
