Metso GP500 Mantle

Mon, 01 Jan 0001 00:00:00 +0000

Cast from premium high-manganese steel (Mn18Cr2 standard; Mn22Cr2/TiC ceramic-reinforced MANDATORY for pebble crushing & high-silica/abrasive ores), the GP500 Mantle features a deep, ultra-high-mass profile with an extra-thick, weighted lower heel section specifically engineered to combat “bell-mouthing” (radial growth) inherent to long-stroke, high-inertia operation on the secondary/pebble duty cycle. The precision-machined spherical seat, heavy-duty hydraulic lock nut thread (M140/M150 class), and backing groove are held to micron tolerances. This guarantees 360° intimate contact with the massive crusher head cone, eliminating the micro-movement that causes catastrophic head cone fretting fatigue—a 150k-220k+ USD capital asset risk. The cavity profiles (C, M, F) are geometrically locked to the GP500 Bowl Liner to preserve the steep crushing angle and interparticle compression efficiency deep into wear life.

Cast from premium high-manganese steel (Mn18Cr2 standard; Mn22Cr2/TiC ceramic-reinforced MANDATORY for pebble crushing & high-silica/abrasive ores), the GP550 Mantle features a deep, ultra-high-mass profile with an extra-thick, weighted lower heel section specifically engineered to combat “bell-mouthing” (radial growth) inherent to long-stroke, high-inertia operation on the 600 kW duty cycle. The precision-machined spherical seat, heavy-duty hydraulic lock nut thread (M155/M160 class), and backing groove are held to micron tolerances. This guarantees 360° intimate contact with the massive crusher head cone, eliminating the micro-movement that causes catastrophic head cone fretting fatigue—a 200k-280k+ USD capital asset risk. The revised cavity profiles (C, M, F, EF) are geometrically locked to the GP550 Bowl Liner to preserve the steep crushing angle and interparticle compression efficiency deep into wear life.
