Introduction of ball mill
From the wet process ball mill to dry process ball mill, our ball mill can be used in grinding non-metallic materials,like limestone,slag,pozzolona,Gravel,sandstone, gypsum,coal ,clinker and so on. The ball mill can be used in cement plant, quick lime plant, gypsum plant, coal plant, slag grinding plant, any other plant to grind stone.
We can produce cement ball mill to grind clinker ,gypsum and other mixed material from capacity 15tph to 150tph, the raw material grinding ball mill is to grind limestone, sandstone, clay and iron ore or other corrective material ,the capacity is from 20tph to 195tph,the smallest size of cement mill we have produced is diameter 1.8meters, the biggest size of cement mill we have produced is diameter 5 meters.the smallest size of Raw material grinding mill is diameter 2.2 meters, the biggest size of raw material grinding mill is diameter 4.8 meters. The ball mill can used in wet process or dry process.if you have any inquiry on wet process or dry process,please contact with me.
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.
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.
