  • A Comparison of Three Types of Coal Pulverizers

    The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed decreases with mill size and remains constant for a given mill diameter.Modelling of vertical spindle mills. Part 1: Sub-models,Mar 01, 2015· Grinding of coal to this level of fineness is referred to as coal pulverisation. The Vertical Spindle Mill (VSM) is one of the most popularly used grinding devices for pulverised fuel (PF) generation in coal-fired power stations worldwide. According to published figures, coal pulverisation is an energy intensive process.
