a Loesche mill, with a grinding track diameter of only 1.1 metres, was used as long ago as 1935. However, the breakthrough in grinding this type of material on the vertical roller mill did not take place until the beginning of the 1990's. 1935 The first Loesche mill for grinding cement clinker, an LM 11, was commissioned in Joao Pessao, Brazil.

Hammer mills work on the principle that most materials will crush, shatter or pulverize upon impact. The Process: ... coarse material for further grinding, while allowing properly sized materials to pass as finished product. Mill Evacuation: Hard, heavy materials such as glass, stone, coarse wood or metals can exit the mill via ...
