Coal-mill optimisation in coal-fired power stations aids ...

The vertical spindle mill crushes coal by feeding it between a grinding roller and either a bowl, table or ring at the bottom. Coal enters via the coal feed and falls into the grinding zone, where it is crushed by the grinding wheels. The coal particles are spun outwards by the rotation of the grinding table, and transported by the incoming heated air feed to the classifier, which separates ...
