Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a spiral stirring magnetic ball mill lining plate. Background Art

[0002] The utility model belongs to the field of dry and wet grinding ball mills for grinding ore, ceramics, cement, magnetic materials and powder metallurgy, and particularly relates to ball mill liners for small and medium-sized dry and wet grinding ball mills. The inner linings of ball mills mainly include manganese steel, rubber, ceramics, rubber-magnetic and magnetic liners, among which magnetic liners have the advantages of wear resistance, energy saving, ball saving and labor saving, and especially wear resistance is highly valued by the grinding industry, while the liners of most small and medium-sized dry and wet grinding ball mills in the existing ceramics, magnetic materials and powder metallurgy industries are still using old-style liners such as manganese steel and rubber. The inner arc working surfaces of the existing liners are smooth, wavy, reinforced and the like.

[0003] For example, the utility model with application number 201922254452.3 discloses a ball mill lining plate. The utility model adopts the design concept of extrusion filling to seamlessly fill the gap between adjacent spliced ​​lining plates. When the fixing column is inserted into the fixing hole, the seamless block is squeezed out between the pressure block and the extrusion block. The two seamless blocks are extruded and filled, which improves the sealing. There is no need to use cement mortar for filling the joints, which improves work efficiency. The spliced ​​lining plates, seamless blocks and pressure blocks are connected in an assembly manner, which is easy to inspect and replace.

[0004] Similar to the above application, there are still some shortcomings:

[0005] The installation part of the inner lining plate of this type of ball mill does not have a good protective effect. When the ball mill is running, the internal balls will hit the inner lining plate, causing the installation part of the inner lining plate to be hit, which may be damaged or even broken. Then the material will leak from the fallen inner lining plate, affecting the processing progress.

[0006] Therefore, a spiral stirring magnetic ball mill liner is designed to optimize the above problems. Utility Model Content

[0007] The main purpose of the utility model is to provide a spiral stirring magnetic ball mill liner to solve the related technical problems raised in the above background technology.

[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0009] A spiral stirring magnetic ball mill liner comprises a base plate, an anti-collision plate is arranged on the top of the base plate, wear-resistant strips are evenly arranged on the top of the anti-collision plate, a support plate is symmetrically installed on the bottom of the base plate, a mounting plate is fixed on the bottom of each of the support plates, a square groove is opened on the top of each of the mounting plates, a through groove is opened on one side of the mounting plate, a clamping groove is opened inside the through groove, a clamping plate is clamped inside the square groove, a screw is fixed on the bottom of the clamping plate, and an inner screw tube is threadedly connected to the outer side of the screw.

[0010] Preferably: the bottom of the anti-collision plate is evenly provided with mounting rods, the top of the base plate is evenly provided with mounting holes corresponding to the positions of the mounting rods, and the top of the base plate is fixed with a protective strip.

[0011] Preferably, an anti-collision layer is fixed on the top of the anti-collision plate, and a wear-resistant layer is fixed on the bottom of the mounting plate.

[0012] Preferably, the clamping plate is a square plate, and a reinforcement pad is fixed to the bottom of the clamping plate.

[0013] Preferably, a sealing layer is fixed on the top of the protective strip, and anti-slip particles are evenly arranged on the top of the protective strip.

[0014] Preferably, the bottom of the wear-resistant layer is evenly provided with anti-slip grooves, and the wear-resistant layer is a rubber layer.

[0015] The beneficial effects of the utility model are:

[0016] The utility model provides a spiral stirring magnetic ball mill liner, which can adjust the installation position of the spiral stirring magnetic ball mill liner and the ball mill to between the anti-collision plate and the inner wall of the ball mill through the coordinated use of a base plate, an anti-collision plate, a wear-resistant strip, a support plate, a mounting plate, a square groove, a clamping groove, a through groove, a clamping plate, a screw and an inner screw tube, so that the anti-collision plate completely shields the installation position, avoiding damage caused by the collision of the ball medium inside the ball mill to the installation position, thereby improving the protective effect of the spiral stirring magnetic ball mill liner;

[0017] Through the coordinated use of the mounting hole, the protection strip and the mounting rod, the bottom of the anti-collision plate passes through the mounting hole through the mounting rod and is installed on the top of the base plate through the nut. When the wear-resistant strip and the anti-collision plate are impacted by the spherical medium, the impact force is transmitted to the protection strip through the anti-collision plate. Under the elastic force of the protection strip, it plays a buffering and shock-absorbing role, thereby reducing the noise caused by the impact and improving the noise reduction effect;

[0018] Through the coordinated use of the anti-collision layer and the wear-resistant layer, the anti-collision layer protects the top of the anti-collision plate, thereby improving the protective effect of the spiral stirring magnetic ball mill liner. The setting of the wear-resistant layer reduces the friction damage between the mounting plate and the inner wall of the ball mill, thereby improving the practicality of the spiral stirring magnetic ball mill liner.
