and the grinding face. Vertical Roller Mills This mill uses hydraulically loaded vertical rollers resembling large tires to pulverize raw coal fed down onto a rotating table. As the table rotates, the raw coal is pulverized as it passes underneath the rollers. Hot air forced through the bottom of the pulverizing cham-ber removes unwanted moisture and trans-ports the pulverized coal dust up ...

Both grinding table and roller wheels were set to rotate at a speed of 20 rpm. For modeling the coal flow, the coupled Discrete Phase Model (DPM) was used. The DPM model is an Eulerian–Lagrangian approach to modeling coal flow in which coal particles are considered in groups, called parcels. Forces acting on the particles are considered when solving for velocity and trajectories inside the ...

Vertical Roller Mills are commonly referred to as attrition mills because the material, being fed (under pressure) between the grinding elements by means of centrifugal force imparted by the rotating table or by a rotating pendular shaft, is being crushed against itself. As such the primary wear component in the crushing zone is compression which is a direct force that acts 'normal' to the ...
