Coal Grinding
Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills Grinding media consists balls of 3-4 sizes (60mm-30mm) in designed proportions with large sizes in feed end and small sizes in discharge end
Rolling Bearings in Air Separators of Vertical Grinding
Even extremely hard coal can be pulverised very finely in these mills in all load conditions without problems The MPS vertical grinding roller mills now built by the Babcock (BHE) Group were first built in 1958 by the German manufacturer Pfeiffer for crushing and pulverising cement In early 1960 the bowl and roller mills were
What we should pay attention to maintain the vertical mill

Coal Mill
Sawdust is mixed with coal in the fuel yard and the mixture is fed via roller mills to the burners In the tests carried out in 1999 and 2000 when the share of sawdust varied between 1 and 8% on energy it was noticed that milling performance was decreased and that the roller mills mainly dried the larger sawdust particles rather than
