Description

Technical Field

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

[0002] The processing of highly active composite ultrafine mineral admixtures requires crushing and grinding to meet processing requirements. A ball mill is a key piece of equipment for comminuting the material after crushing. This type of grinding equipment, which uses a cylinder filled with a certain number of steel balls as the grinding medium, is common in the chemical raw material processing industry. Therefore, a ball mill is essential for grinding highly active composite ultrafine mineral admixtures.

[0003] Existing ball mills mainly include a rotating cylinder and a rotating drive assembly. Liners and steel balls are installed inside the cylinder. When the drive assembly drives the cylinder to rotate, the material and steel balls roll inside the cylinder, and the collision between the steel balls and the material is used to grind and crush the material. However, existing ball mills are all fixed horizontally, and the hollow shaft of the ball mill is at the same height as the discharge port. Therefore, other equipment is needed to discharge the material from the discharge port during discharge, which is not simple and convenient. Secondly, the ball mill itself does not have the function of screening materials. After the materials are ground, they need to be screened separately. Both ends of the ball mill are open. If the material is relatively dry during the grinding process, the dust generated will easily overflow from both sides, affecting the on-site environment. Therefore, further improvement is needed.
