The roller tries to ride over the bed, but swims through it. Causes a low frequency vertical movement. Snowplowing pushes at the roller, causing a twist in the mill body. When it snaps back, causes a higher frequency torsional vibration. Causes: Too much feed High internal recirculation Not enough grinding Speed of deaeration.

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 energy consumption and grinding energy efficiency.

In the airswept mode, the verticalrollermill and a high efficiency dynamic classifier are suited above each other as a single unit (Fig. 1). Material is fed to the grinding chamber and transported by table rotation to the grinding gap between the fixed grinding rollers and the mill table. Crushing and grinding take place by compressive grinding.
