Mantle & Concave are critical wear-resistant components for cone crushers, functioning as the moving (mantle) and stationary (concave) surfaces that compress and crush hard materials . Manufactured from high-manganese steel composites, these parts are engineered to withstand extreme impact and abrasion in mining, quarrying, and cement production. Our mantle and concave sets are compatible with leading crusher brands, delivering enhanced durability and operational efficiency.
Through modified heat treatment and composite material technology, our mantle & concave offer a 10-15% longer lifespan than traditional counterparts . The high-manganese steel matrix resists deformation even under continuous crushing of hard rock like granite and basalt.
Using disappear mold casting technology, we eliminate flying edges, burrs, and dimensional inaccuracies, ensuring a casting precision of ±0.5mm . This tight tolerance guarantees seamless fit with crushers from Sandvik, Terex, and Metso .
The composite material reduces replacement frequency and lowers overall casting investment costs, delivering a 30% higher return on investment compared to standard wear parts . Reduced downtime further enhances cost efficiency in high-volume operations.

Used in secondary and tertiary crushing of iron ore, copper ore, and gold ore, reducing raw material to manageable sizes for mineral extraction . Ideal for hard rock mining sites with high abrasion requirements.
Crushes granite, basalt, and limestone for construction aggregates, ensuring consistent particle size for concrete and asphalt production .
Processes limestone and clay in cement manufacturing, supporting high-throughput crushing to meet kiln feed specifications .
We offer parts tailored to most major brands, including Sandvik, Terex, and Metso. Provide your crusher model or sample/drawing, and we will produce matching mantle & concave sets .
Disappear mold casting eliminates air pockets and surface defects, resulting in a denser material structure. This improves impact resistance by 25% and reduces premature failure compared to sand-cast alternatives .
