Ball mills are cylindrical devices used to grind materials such as chemicals, ores, and paints. The cylinder is filled with a grinding medium (such as steel balls) and the material to be ground is added to the mill. The rotation of the cylinder causes the grinding medium to cascade, creating an impact and grinding the material.
