May 25, 2017 May 25, 2017 In an air-swept mill, the body of which does not differ significantly in general design from a trunnion overflow mill, a powerful stream of air is passed through the mill and removes the finer particles produced by the grinding process. This stream of powder-laden air is then passed through the classifier and the “oversize” material

Airswept Roller Mills - Bradley Pulverizer Company

Single Pass Air System: With a single pass air system, air is drawn into the mill base, travels through the classifier, bag filter and fan and is then vented out to atmosphere. In addition to being dust free, the air swept grinding zone prevents over-grinding by the air stream lifting the particles of certain sizes out of the grinding zone
