Metso HP800 Mantle - EC/C/F/MF Cavity - Mn22Cr4/TiC Composite

As the largest mantle in the HP series lineup, the Metso HP800 Mantle (Head Liner) is engineered to endure the extreme mechanical stresses and high throughput demands of large-scale mining and aggregate operations. Designed specifically for the HP800 cone crusher—often utilized in pebble crushing, secondary, and tertiary positions—this mantle manages massive feed sizes and crushing forces exceeding 800 kW.

Manufactured via precision sand casting using premium high-manganese steel (Mn18Cr2, Mn22Cr2) or advanced TiC (Titanium Carbide) reinforced ceramic-matrix composites, the HP800 Mantle offers an unmatched balance of surface work-hardening capability and core toughness. The heavy cross-section design resists cracking under severe shock loads, while the optimized profile geometry ensures a consistent crushing chamber volume, maintaining high reduction ratios and superior cubical product shape even as the liner wears.

Precision machining on the seating surfaces and locking threads guarantees perfect concentricity with the main shaft and Bowl Liner, eliminating the risk of “spinning head” events and protecting the expensive crusher head casting.

Key Benefits:

• Heavy-Duty Cross Section: Thicker walls and reinforced critical zones handle the highest clamping forces and impact energies in the HP series.
• Metallurgical Flexibility: Standard Mn18Cr2 for balanced life; Mn22Cr2/TiC Composite for maximum abrasion resistance in taconite, quartzite, or river gravel.
• Precision Thread & Seat Machining: CNC-machined locking threads and spherical seating surface ensure 360° contact fit, preventing mantle lift and head cone fretting.
• Optimized Wear Profile: Engineered “feed-to-discharge” wear progression maximizes metal utilization and maintains CSS stability.
• Head Cone Protection: Full-contact backing design shields the crusher head from stress corrosion and mechanical damage.
