Dry process ball mill
Model PMG Series high efficient ball mill has been designed with the merits of open circuit grinding system and important renovations on traditional ball mills,besides they have all the good advantages of open circuit mills,production capacity has been raised sustantially,product becoms super fine and blaines have been increased,it has provided a new type of grinding equipment for producing high strength grade cement with high output and super finess.
Model PMG ball mill has adopted special intergrate diaphragm and discharge grate to adjust material levels of every chamber so as to increase air ventilation and improve conditions inside mill,meanwhile it has also used new type of lining plate,regulated mill rotation speed,optimized design of pinion&girth gear and lubricating parameters of bearings sso as to increase its operational stability,use life and grinding efficiency.
After being put into practice,it is proved that its output has been increased about 20% and unit product power consumption has been reduced 10%-12% down under the conditions that other parameters have not been changed by comparision to other same sized ball mill,while being operated in open circuit,specific surface of cement could be reached up to 320cm/kg performance of it is up to national advaned standard,it has been awarded as well-known brand product of China building material industry,well know brand product of Jiagnsu Province,state star plan products,appointed manufacture of National building material machinery industry etc.
