In cement production, tube mills having multi-chambers are traditionally used either in open or closed circuit operations. After the introduction of high compression grinding mills (High pressure grinding rolls (HPGR), vertical roller mill (VRM) and Horomill), various circuit configurations have been developed for energy efficient grinding.
Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here.

Figure 1 – DEM snapshots of eHPCC™ grinding chamber being charged. eHPCC™ DESIGN PHILOSOPHY eHPCC™ utilises the mechanism of low-velocity particle-bed breakage; similar to that of vertical-roller mill and high-pressure-grinding-roll (HPGR) technology whose geometries are schematically depicted in figure 2.
It is reported that vertical pregrinder can typical increse the capacity by 30%, and provide power saving in the range of 15-25% in the Indian context. In China, replacement of ball mills with vertical roller mills in finish grinding can reduce energy consumption by 10 to 15 kWh/t-cement, representing a saving between 30 to 40% (MIIT, 2012. p. 26).
