Screening Dry Screening Of Crushed Aggregates

This breakage phenomenon is restricted only to cohesionless materials like fine- (sand, surkhi etc.) and coarse- (gravel, crushed stone etc.) aggregates. Clay and other colloidal materials are thought to have particles that are so small that further reduction in size is inappropriate or, better say, impossible [9], [10]. Due to the continuous ...
