Vertical Spindle Roller Mill. Similar to the ring and ball mill, this mill uses large "tires" to crush the coal.These are usually found in utility plants. Raw coal is gravity-fed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.Hot primary air for drying and coal transport enters the windbox plenum

vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the majority of the particles in the bed are considerably smaller than the thickness of the bed. It is thus necessary that a stable and consistent grinding bed is formed between the rollers and the table of the vertical roller mill
