The angle between the concave liners and the mantle is at its best operating position when they are new. As time and tonnage go by, both wear. Soon the pattern that the ore takes through the crusher begins to change. This is due to wear causing a LIP to be formed at the bottom of the mantle. When the formation of this lip passes a critical ...

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.
