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 and granulated blast furnace slag, in one process. The concept of M- and S-rollers was established in 1992, which is one of ...

Wet grinding of calcified slag was conducted to improve alumina extraction from red mud by the calcification–carbonization method. The grinding operation conditions and mechanism were investigated. The results showed that wet grinding destroyed the compact structure of spherical hydrogarnet and broke down agglomerates. The rough surface of ground hydrogarnet promoted the …
