Ball mill is the key equipment for material grinding after material crushing. It is suitable for grinding various ores and other materials, and is widely used in mineral processing, building materials and chemical industries. Long life performance characteristics. The material enters the first chamber of the mill evenly and spirally from the feeding device through the feeding hollow shaft. The chamber is equipped with a stepped lining plate or a corrugated lining plate, and various specifications of grinding media are installed. When the cylinder rotates at a certain speed around the horizontal axis, under the action of centrifugal force and frictional force, the medium and raw materials contained in the cylinder make it attached to the cylinder liner and taken away by the cylinder, and brought to a certain high. When its own gravity is greater than the centrifugal force, it will be thrown or rolled down from the inner wall of the cylinder, and the material will be hit and ground due to the impact force.

Ball Mill Performance and Features

1.Simple structure, convenient maintenance, high capacity.
2.Easy installation, long-time continuous operation.
3.Wearing parts are wear resistant, with a long life.

Working Principle of Ball Mill

The ball mill is a horizontal tubular rotating device, with two stock bins. It is of grid type and is gear-driven. The materials are sent spirally and evenly into the first stock bin along the hollow axis by feeding device. The stock bin has ladder scaleboard or ripple scaleboard, and has steel balls of different specifications. The rotating tank causes centrifugal force. Under the function of centrifugal force, the steel ball is carried to certain height and falls onto the materials for grinding. After being coarsely grinded in the first stock bin, the materials then enter into the second stock bin (with steel ball and scaleboard) for further grinding. Lastly, the powder is discharged from the grid plate to complete the grinding.
