Performance of the static air classifier in a Vertical Spindle Mill
1. Introduction. In coal power plants, classification of coal particles in a classifier after the pulverization process is important. A high-quality classification can guarantee the delivery of standard PF efficiently, which results in not only primarily reducing the loss of unburned carbon, but also decreasing the slagging potential in the furnace [1].
