Ball mill

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

What does Ball Mill Do?

The ball mill is a device that destroys the raw materials again after they are mined or broken into small pieces to make their particles smaller. From its name, it can be understood that the ball mill is equipped with steel balls in a closed cylinder. Through the rotation of the cylinder, the steel balls fall from high places and collide with
