H5100 Bowl Liner & Mantle | Sandvik Cone Crusher Wear Parts

Technical Specifications: H5100 / CH440 Wear Parts

Our aftermarket replacement parts for the Sandvik H5100 (CH440) are engineered to restore your crusher’s original performance. As specialized crusher part suppliers, we focus on delivering high-grade manganese Cone Crusher Liner sets that withstand the rigors of mining granite, basalt, and iron ore.

Core Advantages: Metallurgy & Processing

The lifespan of a Mantle and Bowl Liner depends entirely on the heat treatment process. We employ strict protocols to ensure our parts don’t just “fit,” but “perform.”

• Water Quenching Technology: All castings are heated to 1050°C-1100°C and rapidly water-quenched. This “toughening treatment” eliminates carbides, ensuring the steel is fully Austenitic. This prevents brittle fractures during the initial crushing phase.
• Work Hardening Capability: Our Mn18Cr2 alloy is designed to self-harden. While the initial hardness is ~220HB, the surface rapidly hardens to >500HB under impact, creating a wear-resistant skin while the core remains ductile to absorb shock.
• Precision Machined Seating: We CNC machine the mating surfaces (the bottom of the mantle and the top of the bowl liner) to strict tolerances. This ensures perfect contact with the Head Center and Top Shell, preventing “liner spin” or backing compound failure.

Choosing the right alloy for your H5100 crusher spares is critical for cost efficiency. We offer three grades:

Field Diagnosis: Optimizing Your Crushing Chamber

As experienced engineers, we know that wear patterns tell a story. Inspect your old H5100 wear parts before disposal:

• Cupping (Wear at inlet only): Indicates feed size is too large or feed is not centered. Consider changing to a coarser cavity (e.g., from F to M).
• Bell-Mouthing (Wear at discharge only): Indicates the crusher is running with a low choke level (not full). This causes “stone-on-metal” crushing rather than “inter-particle” crushing, significantly reducing liner life.
• Oval Wear on Mantle Base: Suggests the mantle came loose. Always check the burning ring and locking nut torque during installation.

Expert Tip: Installation & Bedding

Backing Compound Matters: When installing the H5100 Bowl Liner, never reuse old backing material. We recommend a high-impact epoxy backing with zero shrinkage. Ensure the liners are at ambient temperature (not freezing) before pouring to prevent thermal shock to the epoxy. A void-free backing layer is critical to transferring the crushing force to the frame; without it, even the highest quality manganese steel will crack due to flex fatigue.

Frequently Asked Questions (FAQ)

Q1: How do I identify which cavity (e.g., Medium vs. Fine) I currently have?
A1: The cavity is determined by the shape of the Bowl Liner. The Part Number is usually cast into the top flange or the backing side. If worn off, measure the “A” dimension (open side setting inlet) and consult our engineering team. We can reverse-engineer the profile based on your product output requirements.

Q2: Can I mix a Mn18 Bowl Liner with a Mn13 Mantle?
A2: It is possible, but not recommended. We advise keeping the material grades consistent or using a slightly harder material for the part that wears faster in your specific operation (usually the mantle) to synchronize replacement schedules.

Q3: Are these parts compatible with the newer CH440 model?
A3: Yes, the Sandvik H5100 and CH440 share the same crushing chamber geometry for most configurations. Our parts are fully interchangeable Spare parts manufactured to the original geometric standards.
