Custom Cone Crusher Liner Set Mantle and Bowl Liner High Manganese Alloy Castings for Mine Quarry Secondary Fine Crushing

Product Description

• We specialize in heavy-duty mining wear castings and supply custom-fitted mantle and concave liner sets for cone crushers.
• Material options include high manganese steel, high-chromium alloy and alloy steel, engineered to suit different ore hardness and abrasive working conditions.
• These consumable liners are the core components for secondary and fine crushing circuits.
• Different from the reciprocating squeezing action of jaw crushers, cone crushers break rocks via gyratory eccentric motion.
• The mantle rotates along an offset path, pressing rock against the stationary concave.
• Materials undergo multi-point layered compression inside the crushing cavity.
• This operating mode creates cyclic high contact pressure. Poor material formulation or insufficient casting quality will easily lead to surface spalling, local deformation and accelerated wear.
• We accept custom production based on customer drawings, physical samples or site working condition feedback.
• Multiple cavity profiles are available: coarse, medium and fine.
• For highly abrasive mine ore or quarry stone, we adjust material formulas and internal casting structures to balance impact resistance and wear resistance.

Applications

• Mantle and concave liner sets are critical wear parts for cone crushers, widely used for secondary and tertiary crushing in mineral processing and aggregate plants.
• They are engineered to crush high-hardness ores and rocks, including iron ore, copper ore, gold ore, basalt and diabase.
• Our liners are fully compatible with spring cone, single-cylinder hydraulic cone and multi-cylinder hydraulic cone crushers.
• Main application sites: metal mines, non-metallic mines, quarry crushing stations and mineral concentrators.
• By selecting different cavity profiles, operators can flexibly adjust output particle size to meet diverse finished product specifications.

Support and Services

• Beyond standard castings, our technical team offers professional application consultation.
• Based on your ore properties, feed size and target product granularity, we provide recommendations on material grade selection and cavity type matching.
• Our factory holds ISO 9001, ISO 14001 and ISO 45001 certifications.
• Complete batch production records ensure full traceability.
• Third-party witness inspection is available upon request.
• Bilingual Chinese & English test reports are provided for overseas project acceptance.
• We also share practical guidance on liner installation, commissioning and wear cycle evaluation.

Packing and Shipping

• Mantle and concave are large curved castings. Their working curved surfaces require strict protection against impact damage.
• For ocean shipment, products are secured with metal frame boxing.
• Cushioning materials are applied on curved working faces to avoid scratches, plus waterproof wrapping.
• We perform weighing before shipment.
• Each package is clearly marked with PO number, destination, part name, quantity, gross/net weight and outer dimensions.
• Our logistics team tracks cargo from factory loading to destination arrival to secure reliable delivery.
