Mantle for GP100 Series Cone Crusher

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

Engineered for the Metso GP100™ / GP100S™ cone crusher—the high-efficiency, constant-stroke specialist for secondary and tertiary stages in aggregates (asphalt/concrete chips, manufactured sand) and mining (stationary & portable NW Series)—the GP100 Mantle (Head Liner) is the dynamic wear component that activates the GP Series’ unique “Steep Cavity + Long Stroke” geometry. Unlike HP Series mantles that rely on a pivot point, the GP100 Mantle gyrates with a constant, long stroke at a steep head angle. This demands a casting with precise spherical seating geometry and a reinforced lower skirt to maintain the tight nip angle and extended parallel zone essential for achieving high reduction ratios (up to 6:1–8:1) and superior cubical product shape without “ring bounce” or floating feed.

Metso GP220 Mantle

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

Engineered for the Metso GP220™ / GP220S™ cone crusher—the high-capacity, constant-stroke flagship for heavy-duty secondary and tertiary crushing in major aggregates quarries (rail ballast, high-spec concrete aggregate, manufactured sand) and mining (SAG pebble crushing/SABC circuits, ore preparation)—the GP220 Mantle (Head Liner) is the primary wear component driving the GP Series’ industry-leading “Steep Cavity + Constant Long Stroke” kinematics at 160 kW. Unlike pivot-point designs (HP/MP), the GP220 Mantle gyrates with a fixed, long stroke at a steep head angle. This demands a massive, precision-balanced casting with a heavily reinforced anti-flaring lower heel/skirt to resist the extreme centrifugal forces generated at speed, locking in the Closed Side Setting (CSS) stability required for consistent high reduction ratios (up to 6:1–8:1) and superior cubical product shape under maximum throughput (500–650+ mtph).

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.

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.

Metso HP3 Mantle - EC/C/F/MF Cavity - Mn22Cr4/TiC Composite

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

Designed for the Metso HP3™ cone crusher (commonly integrated into Lokotrack® LT300HP™ and LT330D™ mobile crushing plants), the HP3 Mantle (Head Liner) is engineered for high mobility, rapid liner changes, and versatile secondary/tertiary crushing performance. Despite its compact footprint compared to the HP700/800 series, the HP3 mantle processes high reduction ratios with significant throughput, demanding a wear part that balances work-hardening capacity with structural resilience against tramp iron and variable feed conditions typical in contracting applications.

Metso HP4 Mantle - EC/C/F/MF Cavity - Mn22Cr4/TiC Composite

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

Engineered for the Metso HP4™ / HP400™ cone crusher—the high-capacity standard for secondary and pebble crushing in mining and large-scale aggregates (stationary HP400 / mobile Lokotrack® LT400HP™)—the HP4 Mantle (Head Liner) is a thick-section, precision-machined casting designed to withstand extreme compressive loads and high-inertia gyratory forces. With a 400 kW (536 HP) power draw and large eccentric throw, the HP4 subjects the mantle to severe plastic deformation risk at the lower crushing zone and high-impact fatigue at the feed eye. This mantle is the critical interface for maintaining the HP4’s signature “interparticle crushing” action and high reduction ratio.

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.

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

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

As the largest mantle in the HP series lineup, the Metso HP800 Mantle (Head Liner) is engineered to endure the extreme mechanical stresses and high throughput demands of large-scale mining and aggregate operations. Designed specifically for the HP800 cone crusher—often utilized in pebble crushing, secondary, and tertiary positions—this mantle manages massive feed sizes and crushing forces exceeding 800 kW.

Manufactured via precision sand casting using premium high-manganese steel (Mn18Cr2, Mn22Cr2) or advanced TiC (Titanium Carbide) reinforced ceramic-matrix composites, the HP800 Mantle offers an unmatched balance of surface work-hardening capability and core toughness. The heavy cross-section design resists cracking under severe shock loads, while the optimized profile geometry ensures a consistent crushing chamber volume, maintaining high reduction ratios and superior cubical product shape even as the liner wears.
