Improved gyratory crushing operation by the assessment

2004-11-1  Crusher performance is significantly impacted by liner material wear, wear profile, feed size distribution, feed type, and feed rate (Bearman and Briggs, 1998). This work is based on cone crushers, but the similarities between these types of crushers and gyratory crushers suggest that the results may be transferable to gyratory crushers.
