Vertical roller mill for raw Application p rocess materials

vertical roller mill with separator, cyclone, mill circulation fan, and electrostatic precipitator (EP) and EP fan as shown in Fig.1. By this production increasing, it is expected that operation in the daytime can be shortened and then power cost can be reduced. Cost estimation About 7.3 million US$ (depending on the scale) [1US$=¥110]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.
