Numerical Investigation of Vertical Roller Mill Operation …

In VRM, it is impossible to maintain a particular gap between the table and roller during operation. However, the VRM can be stopped using mechanical or hydraulic systems at minimum gap. The equipment needs to be designed considering the minimum allowable gap. The simulation is carried out with a roller and table gap from 60 to 100 mm.
