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

Engineered for the Metso HP800—the highest-capacity cone crusher in the HP series—the HP800 Bowl Liner (Concave) is a massive, monolithic wear component designed to withstand the brutal forces of large-scale mining, pebble crushing, and high-tonnage aggregate production. With crusher power ratings up to 800 kW (1,070 HP) and feed openings accepting large coarse feed, this liner manages extreme impact energy and sustained abrasive wear.

Cast from premium high-manganese steel (Mn18Cr2, Mn22Cr2) or next-generation TiC (Titanium Carbide) ceramic-reinforced composites, the HP800 Bowl Liner delivers exceptional work-hardening depth and crack-stopping toughness. The heavy-section casting design incorporates reinforced ribs and optimized wall thickness distribution to prevent distortion under massive clamping forces and thermal cycling.

Precision machining on the upper flange, adjustment ring contact face, and locking grooves ensures a perfect seal against the adjustment ring and hopper assembly. This guarantees stable Closed Side Setting (CSS) retention, prevents “ring bounce” on the adjustment cap, and protects the expensive crusher frame from catastrophic wear. The optimized chamber profile (Extra Coarse, Coarse, Medium, Fine, Extra Fine) maintains geometric integrity throughout the wear life, ensuring consistent throughput, reduction ratio, and cubical product shape.

Key Benefits:

• Massive Structural Integrity: Thickest cross-sections in the HP series resist plastic deformation and cracking under peak crushing loads.
• Advanced Material Science: TiC composite options provide 2-3x life over standard manganese in high-abrasion ores (taconite, quartzite, flint).
• Frame Protection Guarantee: Full-contact seating surface and precision-machined flange protect the adjustment ring and main frame from fretting and wash-out.
• Chamber Profile Stability: CNC-verified geometry maintains the crushing angle and parallel zone length, preventing “chamber rounding” and throughput drop-off.
• Optimized for Pebble Crushing: Specific profiles available for critical pebble crushing duties (SABC circuits) where high recirculating loads demand maximum wear resistance.
