The hard material ball mill produced by Qingdao Shina is made of carbon steel. Alumina lining brick is pasted on the inner wall of the ball mill and alumina grinding ball is installed. The main processing of hard materials are quartz, feldspar, zirconium sand, alumina, alumina hydroxide and so on.

The material is loaded into the cylinder by the hollow shaft of the feed end of the ball mill. When the cylinder of the ball mill rotates under the drive of the belt, the grinding ball is carried away by the cylinder by the action of inertia, centrifugal force and friction force. When it is brought to a certain height, it is thrown down by its own gravity, and the falling grinding ball is like a projectile, smashing the material in the cylinder. To achieve a crushing effect.
