There are many reasons for cone crusher's wear:First, give some details on:

1. Product strength, size and its properties
2. Rate through crusher and if continuos or highly intermitent
3. Crusher manuifacturer and size or model
4. Concave and mantle shape being applied
5. How crusher is fed - ie choked or light flow wrt crusher size
This last point is referencing the wear brought about due to product heaving in crusher bowl if you do not keep bowl full. Keeping the crusher opening full holds the rock in the crusher bite from slipping upward during the pinching cycle. When the rock breaks during crushing, much of the explosive fracture causes reverse motion of the material above product unless it is captured.

There are different concave and mantle forms/shapes that are ideal or optimized for certain products, strength and size distribution.
