Grinding elements take the wear and tear of coal

21/02/2013 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
