Metso HP5 Bowl Liner - EC/C/F/MF Cavity - Mn22Cr5/TiC Composite

Engineered for the Metso HP5™ / HP500™ cone crusher—the flagship high-capacity secondary/tertiary crusher for large-scale mining (pebble crushing, hard rock) and major aggregate operations (stationary HP500 / mobile Lokotrack® LT500HP™)—the HP5 Bowl Liner (Concave) is a massive, monolithic casting designed to manage the highest throughput and reduction forces in the HP Series lineup. With a 500 kW (670 HP) power rating, massive feed opening (up to 450mm+ on EC), and high pivot point geometry, the HP5 Bowl Liner endures extreme compressive stress, high-impact slab puncture, and severe sliding abrasion in the parallel zone.

Cast from premium high-manganese steel (Mn18Cr2 standard; Mn22Cr2/TiC ceramic-reinforced highly recommended for mining duty), the HP5 Bowl Liner features an ultra-heavy cross-section with optimized ribbing and a reinforced “feed lip” geometry to resist plastic deformation (“hooking”) under peak choke-fed loads. The precision-machined upper flange, adjustment ring seating surface, and dual locking wedge/bolt systems (upper & lower on most HP5 variants) are held to micron-level tolerances. This ensures a hermetic 360° seal against the adjustment ring, preventing the catastrophic fines migration (“wash-out”) that destroys the expensive adjustment ring threads and frame seating—the #1 capital risk on 500kW class crushers.

The cavity profiles (Extra Coarse, Coarse, Medium, Fine, Extra Fine) are CNC-verified to maintain the HP5’s aggressive nip angle and extended parallel zone, preserving the “interparticle crushing” efficiency that delivers the industry’s best reduction ratio per kWh. Profile integrity is sustained deep into wear life, preventing the throughput-killing “hourglass” wear pattern common on inferior aftermarket castings.

Key Benefits:

• Mega-Duty Structural Integrity: Thickest feed-entry wall sections in HP Series resist slab puncture and hooking on 400mm+ feed.
• Dual-Lock Security: Upper + Lower locking wedge/bolt engagement (standard on HP5/HP500) prevents liner rotation/shift under extreme gyratory torque.
• Adjustment Ring & Frame Insurance: Zero-gap flange machining protects the ~$100k+ USD Adjustment Ring and Main Frame from fretting—critical for 500kW uptime.
• Mining-Grade Metallurgy (TiC Standard Rec): TiC (Titanium Carbide) composite matrix is near-mandatory for SAG pebble crushing (SABC), BIF, and high-quartz ores, delivering 3x+ life vs. Mn18Cr2.
• Unified Mobile/Stationary: Identical casting for LT500HP mobile and stationary HP500. Weight ~3,200–4,000 kg (7,000–8,800 lbs) mandates 30t+ crane/excavator.
• Sustained Reduction Efficiency: Geometry maintains parallel zone length & nip angle, preventing “floating” CSS drift common on worn liners.
