classifier is mounted above the grinding zone. The feeding device for fresh material is arranged in this area where the fresh feed is also mixed with the grits rejected from the classifier (see Figure 1). The main difference between an MPS mill for solid fuels and other MPS mills lies in its pressure-shock resistance. Mill and classifier housing,

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

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.
