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 steelballs. An internal cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other e…Ball Mills  an overview  ScienceDirect Topics,Oleg D. Neikov, in Handbook of NonFerrous Metal Powders, 2009. Tumbling Ball Mills. Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale.. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary,Ball Mill  an overview  ScienceDirect Topics,Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
