Wear Parts Materials in Properties
Manganese
Standard all round manganese level
and the most common for all jaws and cone liners is 18%. Low manganese grade
steel (14%) work hardens slower than higher grade, but is more impact
resistant. Higher levels (22%) are used in very hard and abrasive applications
where significant wear resistance is needed.
Wear Mechanisms in Crushing Chamber
The main wearing mechanism in the
crushing chamber is abrasive wearing. Fatigue wear is also present as wear are
subjected to multiple compression or impact loads.
Wear Factors
Two of the most notable factors in
the wear of crusher wear parts are abrasiveness and crushability of feed
material.
Feed Material Properties
Abrasiveness of the feed material can
be determined in rock laboratories using a test for abrasiveness.
