[0002] Alumina, with the chemical formula Al2O3, is a compound with high hardness, having a melting point of 2054 °C and a boiling point of 2980 °C. It is an ionic crystal that can be ionized at high temperatures and is commonly used in the manufacture of refractory materials. Industrial alumina is prepared from bauxite (Al2O3·3H2O) and diaspore. For high-purity Al2O3, it is generally prepared by chemical methods. Al2O3 has many polymorphs, and currently more than 10 kinds are known.

The material passes through the crushing roller and falls on the stress plate, and then is conveyed to the ball mill by the spiral blade driven by the rotating roller. During the rotation of the spiral blade, the falling material and the mother liquor are continuously conveyed forward to prevent blockage. After the material falls on the stress plate, it vibrates and buffers on the support block in cooperation with the telescopic rod and the spring to protect the feeding structure. When part of the material starts to fall at the top of the feed pipe, it will first hit the guide plate, and the guide plate accurately guides the material to the stress plate. The annular plate on the outer wall of the feed pipe is connected to the reinforcing rod and the feed pipe to reinforce the structure, thus completing the use process of the device for grinding raw material pulp for alumina production.

Figure 2 is a schematic diagram of the structure of the reset element in the first embodiment of the present utility model.

[0021] This embodiment provides a multi-stage grinding equipment for alumina raw materials, including a base 101, a feed pipe 102 and a control component. The control component includes a feed frame 103, a partition plate 104, a feed cylinder 105, a conveyor belt 106 and a driving member. The driving member includes a driving motor 107, an output rod 108 and a transmission component; the transmission component includes a rotating rod 109, a connecting rod 110, an arc rod 111 and a reset element; the reset element includes a guiding column 112, a spring 113 and a reset block 114; through the foregoing solution, when performing the crushing process, when the material is introduced into the crushing box through the feeding port, since the material is directly poured onto the crushing roller at one time, the crushing roller bears more materials, which may affect the crushing effect and speed, thereby affecting the processing progress and being inconvenient for the user to use. It can be understood that the foregoing solution can be used in the prospect of the multi-stage grinding equipment for alumina raw materials and can also be used in the problem of secondary grinding.

[0022] In this embodiment, the feed pipe 102 is installed on the base 101, and through the partition of the partition plate 104, a better crushing effect of the crushing roller is achieved. The crushing roller is a prior art and will not be described in detail here.

[0023] Among them, the feed frame 103 is installed on the base 101 through a support column. The partition plate 104 is slidably connected to the feed frame 103. The feed cylinder 105 is fixedly installed on the upper surface of the feed frame 103. The conveyor belt 106 communicates with and conveys the feed cylinder 105 and the feed frame 103. The driving member drives the partition plate 104 to move. The feed frame 103 has a plurality of slots. The partition plate 104 is located at the slots and is partially located inside the feed frame 103. The conveyor belt 106 is located at the slots. During use, the raw material is poured into the feed cylinder 105. By driving the driving member to rotate, the driving member rotates to drive the partition plate 104 to move repeatedly inside the feed frame 103, thereby realizing that the raw material is equally divided and falls from the feed cylinder 105 onto the conveyor belt 106 and is transported to the feed pipe 102 through the conveyor belt 106 for crushing, solving the problem that when performing the crushing process, when the material is introduced into the crushing box through the feeding port, since the material is directly poured onto the crushing roller at one time, the crushing roller bears more materials, which may affect the crushing effect and speed, thereby affecting the processing progress, and improving the work efficiency.

[0024] Secondly, the driving motor 107 is mounted on the feeding frame 103 through a mounting plate; one end of the output rod 108 is fixedly connected to the output end of the driving motor 107; the transmission component is connected to the other end of the output rod 108, and the rotation of the driving motor 107 drives the rotation of the output rod 108.

The movement of the partition plate 104 drives the movement of the reset block 114, and the movement of the reset block 114 stretches the spring 113. When the rotating rod 109 disengages from the arc-shaped rod 111, the reset of the spring 113 drives the movement of the reset block 114, and the movement of the reset block 114 drives the movement of the partition plate 104, thereby realizing the reciprocating movement of the partition plate 104.

[0027] When the alumina raw material multi-stage grinding device of this embodiment is used, the output rod 108 is driven to rotate by driving the driving motor 107, and the output rod 108 rotates to drive the rotating rod 109 to rotate, and the rotating rod 109 rotates to drive the arc rod 111 to move, and the arc rod 111 moves to drive the partition plate 104 to move, and the partition plate 104 moves to drive the reset block 114 to move, and the reset block 114 moves to stretch the spring 113, and when the rotating rod 109 is separated from the arc rod 111, the spring 113 is reset to drive the reset block 111 to move. 4 moves, the movement of the reset block 114 drives the dividing plate 104 to move, so that the dividing plate 104 can reciprocate, and then the raw materials are equally divided and fall from the feeding barrel 105 onto the conveyor belt 106, and are transported to the feeding pipe 102 for crushing through the conveyor belt 106, which solves the problem that when the material is introduced into the crushing box through the feeding port during the crushing process, the material is directly poured onto the crushing roller at one time, causing the crushing roller to bear more material, which may affect the crushing effect and speed, thereby affecting the progress of the processing, thereby improving the work efficiency.
