The first end of the ball mill is rotatably connected to the first support frame, and the second end of the ball mill is rotatably connected to the second support frame. A gear ring is sleeved on the outer wall of the ball mill, and a gear plate meshing with the gear ring and used to drive the gear ring and the ball mill to rotate is fixedly arranged on the rotating shaft of the reduction motor. A fixed partition is fixedly arranged in the ball mill to divide the ball mill into a left section and a right section, and at least one conical sieve hole is arranged on the fixed partition.

[0003] However, in actual application, the above-mentioned ball mill still has the following problems: since the ball mill is placed horizontally, it is difficult for the aluminum powder after coarse grinding in the left interval to pass through the conical sieve holes and enter the right interval for fine grinding, and the screening effect is not good. In addition, the ball mill is driven by the reduction motor to rotate the ball mill and drive the steel balls to ball-mill the aluminum powder, so the ball milling efficiency is low, which prolongs the processing cycle of the aluminum powder.
