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 the most cost effective and successful LOESCHE innovations.

Progress with grinding aids for VRMs T he effect of grinding aids on the comminution of cement is based on the dispersion of fine particles. It is a misunderstanding that grinding aids for vertical roller mills (VRMs) should stabilise the material bed between the rollers and the table by adhesive forces between the particles. Grinding aids

The Loesche coal grinding mill range is divided into two serial types: Small twin mills constructed to individual specifications (LM 12.2 D to LM 20.2 D), with table diameters from 1,200 to 2,000 mm. Larger mills with two, three and four rollers and modular struc- tures (LM 21.2 D to LM 43.4 D), with table diameters from 2,100 to 4,300 mm.
