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. Pulverized final products, which is called kiln feed raw meal, are collected at the cyclone and EP. Because of large pressure loss at the cyclone and in order to control mill gas flow…
Vertical roller mill optimisation
Vertical roller mills (VRMs) have become the equipment of choice for raw and solid fuel grinding in cement factories. Increasingly modern cement plants also use VRMs for cement grinding. However, opportunities for the optimisation of VRMs are less obvious than with ball mills as all processes of grinding, drying, classification and regrinding take place within the body of the mill.
