Ball Mill Works
Gear to make the mill a circular cylinder, the cylinder ends with end caps with a hollow journal, the end caps of the journal bearing on the bearing, electric motors by mounted on the cylinder rotation in the cylinder body equipped with a grinding mine medium (steel balls, steel bars, or gravel, etc.) and grinding the ore, the total load amount to 25-45% of the effective volume of the cylinder.
Cylinder around the horizontal axis of rotation speed of the provisions of the cylinder body of the grinding media and minerals in the role of the centrifugal force and friction, the cylinder liner raised to a certain height, and then out of the cylinder wall freely spilled drop or throw fall, so that the ore impact and grinding stripping effect and grinding.
