Description

Technical Field

[0001] The utility model belongs to the technical field of ball mills, in particular to a resin-lined high-efficiency ball mill. Background Art

[0002] Resin lined high efficiency ball mill is a kind of high efficiency grinding equipment which uses resin material as lining. It is widely used in fine grinding and dispersion of various high purity materials.

[0003] The discharge port of the existing ball mill is usually equipped with a filter. After the magnesium oxide block is placed in the ball mill, the filter needs to be taken out first, and then the discharge port is sealed with a cover. If the filter is not taken out, the ball milling eggs will collide with the filter during the ball milling process, causing damage to the filter. After the magnesium oxide is ground into powder, the cover needs to be opened again, and then the filter is placed in to intercept the ball milling eggs so that the magnesium oxide powder can be discharged smoothly. This method is more complicated to operate during the discharge process and is inefficient. Therefore, we propose a resin-lined high-efficiency ball mill. Utility Model Content

The handle is turned counterclockwise to drive the threaded rod to rotate, and the annular screen moves toward the inside of the ball mill box. At this time, the sealing cover is away from the discharge pipe, and the discharge pipe can be opened for convenient discharge. This method does not require the disassembly of the annular screen, which is convenient for operation.

When the magnesium oxide block is ball-milled , so that the discharge pipe 132 rotates to the bottom position, and then the handle 313 is rotated counterclockwise to drive the threaded rod 312 to rotate, so that the annular filter 131 moves into the ball mill 1. At this time, the sealing cover 136 is away from the discharge pipe 132, and the discharge pipe 132 can be opened, so that the magnesium oxide powder will be discharged from the annular filter 131, and there is no need to install the annular filter 131 again. In the process of discharging, due to the fineness of magnesium oxide, it is easy to clog the leakage groove on the annular filter 131. By starting the electric motor 331, the rotating column 333 is driven to rotate, and the battery 332 is used to provide power to the electric motor 331.
