Cement Ball Mill

overview. the ball mill for clinker is an efficient tool for fine powder grinding. It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores.the point where the mill becomes a centrifuge is called the critical speed and ball mills usually operate at 65% to 75% of the critical speed. application: ball mill is the key equipment for grinding after the crush process, and it is widely used in the manufacture industries, such as cement, silicate, new building material, refractory cylindrical ball mill is an efficient tool for grinding materials like ores, chemicals, ceramic raw materials, paints etc. into fine powder or fine paste by grinding in a wet way. the ball mill operates by rotating a cylinder with grinding balls like steel, ci, ceramic and pebble balls as grinding media.the ball mill is essentially a large rotating drum, containing several grinding media; normally steel balls. As the drum rotates, the motion of steel balls crushes the clinker. the drum which is divided into two chambers with different sizes of grinding ballsrotates at a speed of approximately rpm.
