Grinding of cement clinker in vertical roller mills is a technology introduced by LOESCHE which was first used in 1935. Almost 30 years ago LOESCHE introduced the first vertical roller mill to grind both cement clinker .
The wet or dry grinding is continued until the particle size which still increases the speed of the next technological step, namely the clinker kilning. In the case of the dry process, the so-called raw meal is ground until the prescribed fineness, and is then mixed according to the given chemical compositions, and then stored in silos.
