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 Srollers was established in 1992, which is one of ...

3. Experimental Bond grindability tests. The ball mill grindability tests were conducted in a standard Bond mill for 90μm test sieve. As received, the slag was finer and hence the clinker was also reduced down to similar fineness by crushing in a roll crusher and − mm samples were used as feed materials for the tests.
