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.

This work concentrates on the energy consumption and grinding energy efficiency of a laboratory vertical roller mill (VRM) under various operating parameters. For design of experiments (DOE), the response surface method (RSM) was employed with the VRM experiments to systematically investigate the influence of operating parameters on …
The required fineness of cement can only be adjusted by the selected fresh material feed. In the case of high pressure comminution with vertical roller mills (VRM) or high-pressure grinding rolls (HPGR), the achievable PSD is much narrower. With such mills, slopes in the range of about 0.95 to 1.1 (VRM) or 1.1 to 1.25 (HPGR) are achievable.
