heat energy of ball mill process

Orbis Machinery: Manufacturing Process Equipment

For particle size reduction, Steel Ball Mills and Ceramic Lined Mills are the most precise and reliable method for fine grinding solids in either a wet or dry state. Because all the energy, produced by the mill, is put into the grinding process, cooling jackets are furnished on mills for heat sensitive materials to control temperature.
