The mantle and concave are the essential wear-resistant components in cone crushers, directly responsible for the size reduction of hard rocks and ores in mining, construction, and aggregate production. These parts form the crushing chamber: the mantle, gyrating with the main shaft, and the stationary concave surrounding it.
As material enters the chamber, it is subjected to intense compressive forces between these two surfaces, being crushed and ground into smaller, uniform particles. Manufactured from high-manganese steel alloys like Mn13Cr2 or Mn18Cr2, these components are engineered to develop extreme surface hardness under impact while retaining a tough, ductile core to resist cracking.
This combination ensures exceptional resistance to abrasion and repeated shock loads, guaranteeing reliable performance in the harshest operating conditions. Their precise geometry and metallurgy are critical for achieving desired product size, maximizing throughput, and minimizing operational downtime in demanding crushing applications.
Huihe Miningparts Co., Ltd. specializes in the design and manufacturing of casting wear parts, including grinding balls, ball mill liners, and crushers.
