Metso GP500 Bowl Liner Concave

Cast from premium high-manganese steel (Mn18Cr2 standard; Mn22Cr2/TiC ceramic-reinforced HIGHLY RECOMMENDED for pebble crushing & high-silica ores), the GP500 Bowl Liner features an extra-heavy-section, deep-profile casting with a massively reinforced feed opening lip & upper chamber engineered to withstand the extreme impact energy of coarse primary product (max feed ~300–350 mm) and the severe sliding abrasion of recycled pebbles. The precision-machined upper flange seating surface and locking interface (compatible with both Legacy GP500 mechanical wedge lock and GP500S hydraulic clamp ring designs) are held to the tightest OEM tolerances in the secondary class. This ensures a hermetic 360° seal against the massive adjustment ring, eliminating the fines migration (“wash-out”) that rapidly destroys the adjustment ring threads (80k-120k+ USD) and main frame seating surface. The cavity profiles (C, M, F) are CNC-verified to synchronize perfectly with the GP500 Mantle, preserving the steep head angle and long parallel zone deep into wear life.

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.

Metso GP550 Bowl Liner Concave

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 GP550 Bowl Liner features an extra-heavy-section, deep-profile casting with a massively reinforced feed opening lip & upper chamber transition engineered to withstand the extreme impact energy of coarse primary product and the severe sliding abrasion of recycled pebbles. The precision-machined upper flange seating surface and hydraulic clamp ring interface (GP550/GP550S utilize the Hydraulic Clamp Ring design as standard—no mechanical wedge legacy variant exists for GP550) are held to the tightest OEM tolerances. This ensures a hermetic 360° seal against the massive adjustment ring, eliminating the fines migration (“wash-out”) that rapidly destroys the adjustment ring threads (100k-150k+ USD) and main frame seating surface. The revised cavity profiles are CNC-verified to synchronize perfectly with the GP550 Mantle, preserving the steep head angle and long parallel zone deep into wear life for superior interparticle crushing efficiency.

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.
