A ball mill is a key equipment for further grinding after materials have been crushed. It is widely used in industries such as cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, as well as glass and ceramics. It is employed for dry or wet grinding of various ores and other grindable materials.

Highlighted advantages

The ball mill is mainly composed of the feeding part, discharging part, rotating part, and transmission part (reducer, small transmission gear, motor, electric control), among other key components. The hollow shaft is made of cast steel, with a replaceable inner lining. The large rotating gear is processed by gear hobbing on castings, and the cylinder is lined with wear-resistant plates, ensuring excellent wear resistance. This machine operates smoothly and reliably.

Based on the material and discharge method, either a dry ball mill or a wet grid-type ball mill can be selected.

Working principle

This machine is a horizontal cylindrical rotating device with external gear transmission, featuring two chambers and a lattice-type ball mill. Materials are evenly fed into the first chamber of the mill through the feeding device via the hollow shaft spiral. This chamber is equipped with step liners or corrugated liners and contains steel balls of various specifications. The rotation of the cylinder generates centrifugal force, lifting the steel balls to a certain height before they fall, thereby impacting and grinding the materials. After coarse grinding in the first chamber, the materials pass through a single-layer partition plate into the second chamber. This chamber is lined with flat liners and contains steel balls for further grinding of the materials. The powdered material is discharged through the discharge grate plate, completing the grinding process.
