"Is the HP3 Mantle the same as the HP300 Mantle?"

"Yes, mechanically they are identical. \"HP3\" is the marketing designation for the crusher generation used in mobile plants (Lokotrack), while \"HP300\" is the crusher model designation. The mantle part numbers, dimensions, and locking mechanisms are fully interchangeable."

"What is the weight of an HP3 Mantle?"

"Typical weight ranges from 450 kg to 650 kg (990 - 1,430 lbs) depending on the cavity profile (EC/C are heavier; F/EF are lighter). This allows handling with the onboard crane on most Lokotrack units or a small mobile crane."

"Which material grade is best for recycling concrete/asphalt with an HP3?"

"Mn18Cr2 is the recommended standard. Recycling feeds often contain rebar (impact) and mixed aggregates (moderate abrasion). Mn18Cr2 provides the best balance of toughness (ductile core) to absorb rebar impacts and surface hardening for aggregate wear. TiC is usually unnecessary unless processing highly abrasive slag."

"Does the HP3 use a hydraulic lock nut or bolts?"

"Modern HP3 crushers (Gen 2/3) use a Hydraulic Lock Nut. Early HP300 units may have used a mechanical lock nut with locking bolts. Our mantles are machined for the Hydraulic Lock Nut configuration (internal thread + locking grooves) as standard. Specify if you have a legacy mechanical nut unit."

"How often should I check the mantle on a mobile HP3?"

"Due to variable feed control (loader-fed vs. regulated feeder) and transport vibration, inspect mantle wear every 500–800 operating hours or during planned screen mesh changes. Mobile plants often suffer from \"under-feeding\" (wearing the lower mantle only) or \"over-feeding\" (ring bounce/upper wear)."

"Can I use HP200 or HP400 mantles on an HP3?"

"Absolutely not. The HP3/HP300 has a unique head cone diameter, thread pitch, seat angle, and height. HP200 is smaller; HP400/HP4 are larger. Forcing an incorrect mantle will destroy the head cone and adjustment ring."

Product Description

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.

Cast from premium high-manganese steel (Mn18Cr2 standard; Mn22Cr2/TiC optional), the HP3 mantle features a precision-machined seating surface and locking thread interface compatible with the HP3’s hydraulic lock-nut system (or mechanical bolted configuration on earlier variants). The optimized cavity profile geometry (Extra Coarse, Coarse, Medium, Fine, Extra Fine) is calculated to maintain the critical “choke-fed” condition in mobile circuits where feed consistency fluctuates. This ensures consistent cubical end-product shape (critical for asphalt/concrete aggregates) and protects the crusher head from fatigue damage during frequent transport and setup cycles.

Key Benefits:

Mobile-Optimized Metallurgy: Mn18Cr2 standard grade offers rapid work-hardening for the intermittent/variable feed common in mobile recycling and aggregate jobs.
Rapid Change-Out Design: Precision thread machining and manageable weight (~450–650 kg / 1,000–1,430 lbs) enable single-crane or hydraulic hammer-assisted swaps, minimizing downtime on site.
Head Cone Protection: Full-contact spherical seating and backing zone shield the expensive head casting from fretting corrosion and stress risers during high-vibration transport.
Profile Versatility: Available in EC, C, M, F, EF profiles to instantly switch production targets (e.g., road base vs. manufactured sand) without mechanical modification.
OEM Interchangeability: 100% dimensional compliance with Metso HP3 / HP300 specifications for seamless mixing with OEM bowl liners.
