Sandvik H5100 Mantle & Bowl Liner | CH440 Cone Crusher Parts

Technical Specifications: H5100 / CH440 Wear Parts

The Sandvik H5100 (rebranded as CH440) is a workhorse in secondary and tertiary crushing. As specialized crusher part suppliers, we manufacture premium replacement liners designed to match the precise internal geometry of the H5100 Hydrocone system. Our parts are engineered to deliver consistent gradation and maximize wear life in abrasive environments.

Core Advantages: Metallurgy & Manufacturing

Producing high-quality Cone Crusher Liner sets requires strict control over the crystalline structure of the steel. Our process ensures reliability:

• Standardized Manganese Alloys: We strictly adhere to ASTM A128 standards. Whether you choose Mn18Cr2 (Standard) or Mn22Cr2 (Premium), the Carbon-to-Manganese ratio is optimized to prevent brittleness.
• Water Toughening Treatment: Castings are heated to >1000°C and rapidly quenched in water. This critical process ensures a fully Austenitic structure, allowing the liner to absorb massive shock loads without cracking.
• Precision Machined Surfaces: The mating surfaces of our Mantles and Bowl Liners are CNC machined to ISO 2768 tolerances. This ensures a tight fit with the Head Center and Top Shell, preventing the liner from spinning during operation.

Field Diagnosis: When to Change Your H5100 Liners?

Preventative maintenance of Wear parts is key to efficiency. Watch for these signs in your H5100/CH440:

• Capacity Drop: If the crusher’s throughput decreases by >10% despite full power draw, the liner profile has likely degraded, reducing the volumetric capacity of the chamber.
• “Bell-Mouth” Wear: Excessive wear at the bottom (discharge) but little at the top indicates the crusher is being “trickle fed.” This prevents work-hardening and accelerates wear.
• Liner Thickness: Replace the mantle when the wall thickness reaches approximately 20-25mm to avoid the risk of the liner splitting and damaging the main shaft.

Expert Tip: Installation & Backing Compound

Crucial for Hydrocones: When installing the H5100 Bowl Liner, the quality of the backing compound is non-negotiable. We recommend using a high-impact, zero-shrinkage epoxy. Ensure the pour is continuous to avoid air pockets. Warning: Never operate a new mantle without checking the “Head Nut” tightness after the first 4 hours of crushing. As the backing compresses and the manganese flows, the nut often loosens, which is the #1 cause of head center damage.

Frequently Asked Questions (FAQ)

Q1: Are H5100 parts compatible with the Sandvik CH440?
A1: Yes. The Sandvik H5100 was renamed the CH440. In most cases, the wear parts (Mantle and Bowl Liner) are identical and fully interchangeable. Our Spare parts are manufactured to the original H5100/CH440 geometric specifications.

Q2: How do I choose between an’A’ (Coarse) and’B’ (Fine) chamber?
A2: Chamber selection depends on your feed size and desired product output. A “Coarse” chamber takes larger feed but produces less fines. A “Fine” chamber is for smaller feed and maximizing sand production. Contact our engineering team with your feed analysis for a specific recommendation.

Q3: Why is the new mantle magnetic?
A3: High manganese steel (Austenitic) should be non-magnetic. If a new mantle is slightly magnetic, it may indicate improper heat treatment (carbide precipitation) or surface work-hardening from machining. Our parts undergo strict quality control to ensure they are non-magnetic and fully austenitic before shipping.
