One of the most popular models is the vertical spindle mill static classifier. In this device, roller bearings crush the coal coming in from a central chute against a bowl. The particles, which have a wide size distribution, are displaced by the bowl's rotation to the outer periphery of the grinding plate. Upward swirling air induced by angled ...
