Metso GP330 Bowl Liner Concave

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

Cast from premium high-manganese steel (Mn18Cr2 standard; Mn22Cr2/TiC ceramic-reinforced HIGHLY RECOMMENDED for pebble crushing & high-silica aggregates), the GP330 Bowl Liner features a heavy-section, deep-profile casting with a reinforced feed opening lip engineered to withstand high-energy impact from coarse, slabby feed (max feed ~200–230 mm) and the extreme abrasion of recycled pebbles. The precision-machined upper flange seating surface and locking interface (compatible with both Legacy GP330 mechanical wedge lock and GP330S hydraulic clamp ring designs) are held to the tightest OEM tolerances in the tertiary class. This ensures a hermetic 360° seal against the adjustment ring, eliminating the fines migration (“wash-out”) that rapidly destroys the adjustment ring threads (~60k USD) and main frame seating surface. The cavity profiles (C, M, F, EF) are CNC-verified to synchronize perfectly with the GP330 Mantle, preserving the steep head angle and long parallel zone deep into wear life.

Metso GP330 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 abrasives), the GP330 Mantle features a deep, 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 tertiary/pebble duty cycle. The precision-machined spherical seat, heavy-duty hydraulic lock nut thread (M120/M130 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 75k-110k+ USD capital asset risk. The cavity profiles (C, M, F, EF) are geometrically locked to the GP330 Bowl Liner to preserve the steep crushing angle and interparticle compression efficiency deep into wear life.
