Abstract
A rotary solids crusher has three product exits for selectively removing product particle sizes produced by secondary, tertiary, or fine grind crushing. In the fine grind mode, the crusher has an unobstructed vertical attrition chamber from which air-entrained particles exit at high velocity, and are subsequently classified by particle size using the energy inherent in the rapidly moving stream to effect settling; e.g., by gravity or in centrifugal separators.
