Vertimill VS Ball Mill Grinding & Classification Circuits
Basically, vertical mills in different models have less capacity than ball mills As I know, just in cement raw material grinding, vertical roller mills have been developed O OberstGruppen 8 years ago OberstGruppen 8 years ago ie Vertical Roller Mill vs conventional Ball Mill If we instead focus on wet grinding,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 pebblesBall mill
Vertical Roller Mill VS Roller Press in Cement Industry
With the continuous development of grinding technology, there are two kinds of cement grinding equipment with lower energy consumption, one is vertical roller mill, and the other is roller press The two types of equipment are different in grinding mechanism, structure design, and product performance, but each has its own advantages 12016年10月5日· The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials The overall grinding circuit efficiency and stability are improved The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended 25EnergyEfficient Technologies in Cement Grinding | IntechOpen
