Air Swept Mill - Mineral Processing Metallurgy

2021-3-22  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, rejected by the classifier, is returned to the mill
