Description

Technical Field

[0001] The utility model relates to the technical field of ore dressing processing, and particularly relates to an automatic hierarchical sub-mesh grinding device for ore dressing. Background Art

[0002] At present, ore dressing is a process of separating useful minerals from gangue minerals according to the physical and chemical properties of different minerals in the ore. After the ore is crushed and ground, methods such as gravity separation, flotation, magnetic separation, and electrostatic separation are used to separate the useful minerals from the gangue minerals and make various symbiotic (associated) useful minerals separated from each other as much as possible, removing or reducing harmful impurities to obtain raw materials required for smelting or other industries. The ore dressing process of the ore is completed in the ore dressing plant, generally including the following three most basic technological processes, in the order of preparation operation, separation operation, and treatment operation, among which the preparation operation is further divided into processes such as crushing, grinding, screening and classification, and ore washing.

[0003] According to an automatic hierarchical sub-mesh grinding device for ore dressing provided by application number CN201920728023.2, which includes a box body, an opening communicating with the outside is provided on the inner wall of the right end of the box body, and a second box body with the bottom fixedly connected to the ground and the left end communicating with the outside is provided on the right side of the box body. The beneficial effect of the utility model is that the structure of the utility model is simple and the operation is convenient. It can grind the ore into multiple meshes at one time, and can automatically isolate and collect the ground ore powder with different meshes, solving the situation in the existing equipment that the ore can only be ground into a single specified mesh at a time and manual feeding and discharging are required, eliminating the need for multiple feeding and discharging and changing grinding tools with different meshes. The whole process is automated, simple, efficient, convenient and fast.

[0004] However, the above device performs repetitive operations in the crushing and grinding work, and the working efficiency is slow. After injecting the raw materials once, it is necessary to wait for the raw materials to be unloaded before injecting the materials again to continue crushing. And during the process, the raw materials that have reached a certain mesh are repeatedly operated, increasing the processing time and the load of the crushing device. Summary of the Utility Model

Detailed implementation manners

[0019] As Figure 1 , 2 shown, an automatic hierarchical classification grinding device for ore dressing of the present utility model includes a grinding box body 10 for arranging components, a cavity 11 arranged in the grinding box body 10, and a grinding component 20 arranged in the cavity 11; the grinding component 20 includes a first grinding box 21, a second grinding box 22, and a third grinding box 23 which are sequentially and staggeredly arranged in the cavity 11 from top to bottom. The grinding mesh number set by the first grinding box 21 is greater than that set by the second grinding box 22, and the grinding mesh number set by the second grinding box 22 is greater than that set by the third grinding box 23.

[0020] In this embodiment, the mesh numbers that the first grinding box 21, the second grinding box 22, and the third grinding box 23 in the grinding component 20 can grind increase sequentially. On the one hand, during grinding, the ore can be ground and processed sequentially, reducing the load of each grinding device, and the grinding effect of the ore can be better.

[0021] As Figure 1 , 3 shown, the first grinding box 21 includes a fixed grinding plate 211 arranged on the inner wall of the grinding box body 10, a power box 212 arranged on the inner wall of the grinding box body 10, a telescopic rod 213 penetrating through the side wall of the power box 212, and a movable grinding plate 214 arranged at the execution end of the telescopic rod 213 and located on one side of the fixed grinding plate 211; the first grinding box 21 has the same structure as the second grinding box 22 and the third grinding box 23. A feeding port 14 penetrates through the top of the grinding box body 10, a discharging port 15 penetrates through the bottom of the grinding box body 10 and is located at the discharging port of the third grinding box 23. A cavity 11 is arranged in the grinding box body 10, and a material guiding plate 13 is arranged in the cavity 11 and on the other side of the inner wall of the grinding box body 10. The material guiding plate 13 is located below the discharging port of the second grinding box 22. The material guiding plate 13 is inclined and the discharging end is connected to the top of the power box 212 in the third grinding box 23.

[0022] In this embodiment, the ore is injected from the feeding port 14. The telescopic rod 213 works to drive the movable grinding plate 214 to move. The movable grinding plate 214 and the fixed grinding plate 211 cooperate to grind the ore. The ground ore falls into the second grinding box 22 for grinding of a larger mesh number. Finally, it is injected into the third grinding box 23 through the material guiding plate 13 for further grinding treatment. After grinding, it is discharged through the discharging port 15 for loading and transporting by truck.

[0023] As Figure 1 , 2 shown, the filter plate 12 disposed in the cavity 11 and on one side of the inner wall of the grinding box body 10 is located below the discharge port of the first grinding box 21. The filter plate 12 is inclined and the discharge end is connected to the top of the fixed grinding plate 211 in the second grinding box 22. The feed port of the first grinding box 21 and the discharge port of the third grinding box 23 are on the same vertical line

[0024] It should be noted that in this embodiment, among the ore materials ground in the first grinding box 21, some of the smaller ore materials that have been ground directly fall from the filter plate 12 disposed below the discharge port of the first grinding box 21 into the third grinding box 23 on the same vertical line for grinding treatment of the ore materials, thereby improving the grinding efficiency of the ore materials, reducing unnecessary repeated processing, increasing the load of the device, and thus reducing the processing time.

[0025] The working principle of the present utility model is as follows:

[0026] After the present utility model is completely powered on, the ore materials are injected from the feed port 14. The telescopic rod 213 works to drive the movable grinding plate 214 to move, and the movable grinding plate 214 and the fixed grinding plate 211 cooperate with each other to grind the ore materials; among them, among the ore materials ground in the first grinding box 21, some of the smaller ore materials that have been ground directly fall from the filter plate 12 disposed below the discharge port of the first grinding box 21 into the third grinding box 23 on the same vertical line for grinding treatment of the ore materials. The larger part of the ground ore materials falls into the second grinding box 22 through the inclined filter plate 12 for grinding of a larger mesh size, and finally is injected into the third grinding box 23 through the guide plate 13 for further grinding treatment. After grinding is completed, unloading is carried out through the unloading port 15 for loading onto a vehicle; when the work of the third grinding box 23 of the device is turned off, the mesh size of the ore materials discharged from the unloading port 15 can be made smaller to process larger ore materials; similarly, when only the first grinding box 21 is used for grinding, it can be changed to process larger ore materials.
