Ball Mill

What is a ball mill?

The ball mill is the key grinding equipment for powder making the crushed material. This type of grinding machine is to put a certain number of steel balls in its drum body as grinding medium, the materials are ground and mixed by the impact of the falling steel balls.

Ball mill working process and main parts

How does a ball mill work?

*The main body of a ball mill is a big cylinder with a big gear on one end, in the cylinder, added many steel balls as grinding medium

1. The motor drives the cylinder to rotate through the big gear on the end of the cylinder.

2. The rotation of the cylinder generates centrifugal force, which brings the steel ball to a certain height and then falls down, which has a heavy impact and grinding effect on the material.

3. During wet grinding, the final product is discharged by the flow of water. During dry grinding, the final product is discharged by the airflow.

Ball mill with air classifier

Ball mill can also be equipped with air classifier to carry out fine powder grinding task with dry method, ball mill with ordinary classifier can output final powder size with 45 micron. And superfine ball mill classifier system can output micro powder with 10 micron. In cement grinding plant, ball mill is also used to cement clinker grinding with large-scale high-efficiency air classifier, the final cement specific area is about 360㎡/kg
