Mining Crusher & Steel Mill Equipment Spare Parts Manufacturer and Exporter
Integrated foundry, forging shop, and precision CNC machining facility — supplying high-durability cone crusher wear parts for global mining operations, alongside heavy-duty rolling mill rolls and continuous casting machine (CCM) components for steel plants with 16+ years of international export experience.
One-Stop Direct Manufacturer for Mining & Metallurgy Procurement
Heavy mining plants and metallurgical steel mills face the same operational challenge: mechanical wear parts and heavy rotating equipment must deliver zero-defect reliability, as unscheduled downtime on a crushing circuit or rolling line costs tens of thousands of dollars per hour. YK Chanshine bridges both mission-critical sectors. As a direct manufacturer with in-house casting, forging, heat treatment, and precision machining, we eliminate intermediary markups and supply custom-engineered wear parts and capital equipment built to exact OEM tolerances.
1. Mining Crusher Equipment & Wear Spare Parts
We engineer and cast wear-resistant replacement parts compatible with major global crusher brands (including Metso, Sandvik, Symons, Terex, and customized specifications) across hard-rock mining and quarrying applications.
High Manganese Cone Crusher Mantle, Concave & Bowl Liners
Mantles and concaves (bowl liners) endure severe impact and abrasive wear. We cast crusher liners in premium austenitic manganese steels (Mn13Cr2, Mn18Cr2, Mn22Cr2, and proprietary micro-alloyed compositions). Liner cavity profiles are tailored to your specific reduction stages — from coarse primary and secondary crushing to tertiary and fine short-head crushing circuits.
Premium manganese steel mantle and concave bowl liner castings staged for export shipment.

Crusher Main Frames, Eccentric Assemblies & Shaft Castings
In addition to sacrificial wear liners, our foundry produces high-integrity structural components — including annealed cast steel main frames, bronze and ductile iron eccentric bushings, countershaft assemblies, and high-strength alloy main shafts for both rebuilds and OEM assembly.
Heavy-duty main frame and eccentric assembly castings machined to strict dimensional tolerances.

Complete Cone Crusher Units (Factory Assembled & Tested)
For mining and aggregate operators upgrading or replacing crushing lines, YK Chanshine builds complete hydraulic and compound cone crusher units, factory-tested under load before crating and export.

2. Steel Mill Rolling Mill Equipment & Mechanical Spares
From hot strip and wire rod mills to cold rolling and section mills, we manufacture heavy rotating components and mill infrastructure designed to withstand thermal cycling and high rolling pressures.
Forged & Cast Rolling Mill Work Rolls and Backup Rolls
We manufacture custom work rolls and backup rolls through electric furnace melting, ESR refining, open-die forging, differential heat treatment, and precision CNC grinding. Metallurgical grades include forged alloy steel (60CrMoV, 86CrMoV7), high-chromium steel/iron, indefinite chill cast iron (ICCI), and High-Speed Steel (HSS). For detailed grade comparisons and wear data, visit our dedicated Rolling Mill Rolls page.
Forged alloy steel rolls staged post-heat treatment prior to final journal and barrel machining.
Precision CNC turning of roll body and drive ends to achieve tight concentricity and surface finish.
Roll finishing bay equipped with CNC cylindrical grinding, hardness testing, and ultrasonic non-destructive testing (NDT).
Mill Stand Housings, Roll Chocks & Motorized Roller Tables
We fabricate and recondition rolling mill stands, cast steel roll chocks (bearing blocks), and complete motorized roller table conveyor lines engineered for continuous billet, bar, and strip transport.
Heavy cast steel rolling mill housing assembly fitted with precision-machined roll chocks.
Motorized mill roller table segments equipped with industrial drive units and heavy-duty roller bearings.
3. Continuous Casting Machine (CCM) Spares & Mold Components
Continuous casting demands extreme thermal conductivity and mechanical wear resistance at the liquid steel meniscus interface.
Copper Mould Tubes (Straight & Curved)
We manufacture copper mold tubes for billet, bloom, and slab casters in premium copper alloys (CuAg0.1 / Silver-bearing copper and CuCrZr / Chromium-Zirconium-Copper). Internal bore tapers (single, multi-parabolic, or diamond taper) are CNC precision-formed, finished with multi-layer hard chrome (Cr) or Ni-Cr / Ni-Co coatings for extended casting campaign life. Review complete specifications on our Copper Mould Tube page.
Precision-tapered straight copper mould tubes machined and polished prior to internal electroplating.
Curved copper mould tubes engineered for radial continuous casters producing high-grade blooms and slabs.
CCM Mold Assemblies, Segment Rolls & Mechanical Spares
We supply full mold jacket housings, oscillation assemblies, internally cooled segment rolls, withdrawal and straightening rolls, and dummy bar heads. Find comprehensive component details on our CCM Spare Parts page.

Frequently Asked Questions (FAQ)
Can you manufacture cone crusher wear parts to match OEM part numbers or custom drawings?
Yes. We can produce mantles, concaves, and bowl liners directly from your equipment model, OEM part numbers, or 2D/3D technical drawings. We also formulate custom manganese alloys (such as Mn18Cr2 or Mn22Cr2) to optimize wear life for high-silica or high-impact ores.
What information is required to receive a quotation for rolling mill rolls?
Please provide your mill stand type (roughing, intermediate, or finishing), barrel diameter, barrel length, neck/journal dimensions, current roll material, and target rolling tonnage. Review available grades on our Rolling Mill Rolls page.
How do you guarantee the quality and tolerances of copper mould tubes?
Each copper mold tube undergoes 100% CMM dimensional inspection, multi-point internal taper profiling, coating thickness measurement, and hydrostatic pressure testing before export crating. Complete TDS is available on our Copper Mould Tube page.
Do you supply complete crusher units in addition to spare parts?
Yes. In addition to replacement castings and wear parts, we assemble and test complete heavy-duty cone crushers and primary jaw crushers ready for turn-key site commissioning.
Can we consolidate mechanical spares with refractory shipments to save freight?
Absolutely. As a direct supplier of both refractory solutions and mechanical equipment spares, we regularly consolidate shipments for steel mill clients to lower container shipping costs and simplify customs clearance.
