Cement Ball Mill

The cement mill is composed of horizontal cylinder, hollow shaft and other parts. The cylinder is long round barrel, and there are grinding media in it. The cylinder is made of steel plate, and there is steel liner fixed on the cylinder. The grinding media are usually steel balls, which are placed in the cylinder according to different diameters and certain proportion. The grinding media can also be steel forgings. When the cylinder rotates, due to the centrifugal force, the materials and grinding balls press close to the liner; due to the frictional force, the cylinder send the materials and grinding balls to a certain height; and then due to the gravity, the materials and grinding balls fall simultaneously and the grinding balls crush the materials. Meanwhile, sliding friction generating between the materials and liner grinds the materials, achieving the purpose of grinding the materials.
