A cement mill (or finish mill in North American usage), These have been used for many years for the less exacting raw-milling process, but recently roller mills, in combination with high-efficiency separators, have been used for cement grinding, Cement milling is the largest user of electric power on a cement plant, and because.
Cement is then finally produced by finely milling the clinker, which is the main component, as well as gypsum and other additives (fly ash, slag, pzolane, lime filler, etc.). The milling process may involve the use of vertical mills or else, more often, tubular mills with one, two or three chambers, operating in an open or closed circuit.
Cement ball mill is a kind of cement grinding equipment commonly used in cement plants. It is mainly used for grinding materials in cement clinker section. Cement ball mill is widely used in cement production, silicate products, new building materials, refractories, fertilizers, black and non-ferrous metal mineral processing, glass, ceramics, and other industries.

Grinding of cement and/or granulated blast-furnace slag – Material separation in the filter The cement components are ground, dried, and classified in the Pfeiffer vertical roller mill. Moist feed materials can be fed to the mill separately from warm and dry feed materials.
In the grinding process heat will be generated and the cement will be heated up. The temperature of the cement leaving the mill will be dependant on the temperature of the materials (especially the clinker) fed to the mill and to features of the mill and the grinding process. It will typically be in the range from 90 to 120 deg. C.
