What is a ball mill?

Coal mill is also called coal pulverizer or coal grinder. It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are air-swept ball mill and vertical roller mill.. At present, most cement plants use coal as the main fuel in the clinker production process.

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.

Temperature Of Coal –Air Mixture At Mill Outlet The temperature of pulverised coal and air mixture at pulveriser outlet should be maintained at least 15 ºC Above the dew point of air at pulveriser pressure to avoid condensation and consequent plugging of the coal pipes. The pulveriser mill outlet temperature should be

The most used coal mills in cement plants are air-swept ball mill and vertical roller mill. At present, most cement plants use coal as the main fuel in the clinker production process. The standard coal consumed by the new dry process for producing 1 ton of cement clinker is usually between 100 kg and 130 kg, and the fuel cost accounts for about
