Metso GP550 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 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.

Metso HP5 Mantle - EC/C/F/MF Cavity - Mn22Cr4/TiC Composite

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

Engineered for the Metso HP5™ / HP500™ cone crusher—the 500 kW (670 HP) flagship for high-tonnage mining (pebble crushing, hard rock secondary) and major aggregate production (stationary HP500 / mobile Lokotrack® LT500HP™)—the HP5 Mantle (Head Liner) is the largest, heaviest, and most structurally critical mantle in the HP Series. It manages the highest gyratory inertia and compressive loads in the lineup. With a massive head diameter, high pivot point, and long stroke, the HP5 subjects the mantle to extreme centrifugal flaring forces at the lower skirt and severe impact fatigue at the feed eye. This mantle is the primary determinant of the HP5’s industry-leading reduction ratio and cubical product shape.
