High-efficiency Separator/Classifier for Coal Grinding ...

Separators and classifiers send larger particles so that they can be sent back to mill for further grinding. Separators or classifiers with higher efficiency separate larger particles more accurately and thereby reduce over-grinding and decrease mill energy consumption. By replacing the external separator to ball mills with higher efficiency external separators, energy consumption in the mill ...

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 ...
