The Development Of Vertical Roller Mill In Cement Industry Evolution Vertical roller mill is developed from l906, which has yet to be improved during the past hundred years, experienced by centrifugal force for roller pressure to the spring pressure and pressurized with hydraulic pneumatic spring system up to now.By grinding material from the soft to medium-hard coal cement raw material to the hard brittle cement clinker and slag. For cement industry, the invention of NSP kiln technology, double rotary kiln production and large scale, making the vertical roller mill structure has been constantly improved and large to meet the requirements of a kiln with grinding.In order to satisfy the cement plant process line of grinding coal, cement raw meal grinding, ground cement clinker and slag, cement machinery manufacturers around the world have developed its own brand of vertical roller mill.
