Product details


Concave is the core component of cone crusher.The concave is under strong force, high frequency, repeated strain force in the actual operation process.Therefore,the concave quality is directly related to the working life of the cone crusher, it also put forward higher requirement to its internal quality and mechanical properties

Strictly control the quality to ensure the concave is well-integrated with cone crusher from raw material,process design to cast.

Mantle,concave material is Mn13Cr2,Mn18Cr2 and mainly wear-resistant parts for cone crusher and adopts special heat treatment.Its service life is longer than the traditional high manganese steel by 10%.It has good performance in different working conditions and can reduce maintenance costs.


1. Crusher wearing parts are of highest standard and tested constantly to ensure high quality

2. High manganese cone concave and mantle are used in cone crusher which is the most important parts of cone crusher, the lifetime will last two times than before after treatment.
