BACKGROUND

[0002] When hard alloy powder is processed, it needs to be ground by corresponding ball mill. After being ground by ball mill, the uniformity, density and other properties of hard alloy powder can be significantly improved, and the air holes, inclusions and defects of hard alloy powder material can be reduced to improve the density and strength of the material.

[0003] The existing hard alloy powder processing ball mill mostly uses conventional ball mill, which mostly includes a fixed ball mill cylinder and grinding balls arranged in the ball mill cylinder. The ball mill cylinder is driven to rotate at moderate speed by a rotating drive mechanism to drive the grinding balls arranged in the ball mill cylinder to perform ball milling operation on the material. Due to the large particle size difference of the hard alloy material before grinding, the existing method is to directly feed all batches of hard alloy material into the ball mill cylinder, and then continuously grind. As the grinding process advances, the material meeting the fineness is filtered and discharged. Directly feeding hard alloy material with large particle size difference into the grinding operation will adversely affect the grinding effect and efficiency.

[0004] Therefore, the purpose of the present utility model is to design a ball mill material pretreatment device that can directly classify and screen the material during the ball milling process, and can feed the classified and screened material as needed to ensure the ball milling effect and efficiency.
