Heavy Duty Mining Feeding and Conveying Equipment Manufacturer

Shenyang Muren Machinery manufactures heavy-duty mineral feeding and conveying equipment—including apron feeders, vibrating feeders, and troughed belt conveyors—for mining operations, quarries, and bulk material handling plants. Engineered to sustain continuous operation under primary crusher drop zones and high-impact loading bins, our systems handle raw ores, crushed rock, and abrasive mineral bulk at capacities up to 6000 t/h.

Belt Width: 650 mm to 2400 mm
Belt Speed: 1.25 m/s to 4.5 m/s
Structure Types: C-channel stringers, lattice truss spans, or overland enclosed gallery structures

Application and Equipment Compatibility

Metallic Mining

Iron ore dump hoppers, copper primary jaw crusher feeding, gold heap leach conveyance, and underground ore pass recovery.

Quarries and Aggregates

Granite, limestone, basalt, and river rock processing lines.

System Integration

Seamless drop-point matching with primary jaw crushers, gyratory crushers, vibrating screens, surge bins, and stacker-reclaimers.

Custom Manufacturing and OEM Engineering

We engineer feeding and conveying systems according to site elevation drawings, material characteristics, and existing plant footprint retrofits:

Impact Deck Protection: Heavy-duty impact rails placed directly below flight pans beneath truck dump zones to prevent permanent pan deflection.

Wear Liner Upgrades: Replaceable liner plates in NM400, NM500, or 13% Mn steel bolted to pans and hopper skirt walls.

Drive Configurations: Electromechanical planetary gear reducers, variable frequency drives (VFD), or direct-drive hydraulic motor assemblies for soft-start under full load.

Environmental Sealing: Dust containment covers, skirtboard sealing systems with dual-lip rubber skirts, and integrated spray bar mountings.

Manufacturing and Quality Control

Structural frames and mechanical components are fabricated in-house under monitored manufacturing protocols:
Steel Plate Profiling -> CNC Machining of Frame Centers -> Submerged Arc Welding (SAW) -> Structural Stress Relief -> Chain Sprocket and Roller Hardening -> Trial Assembly and Dry Run

Weld Integrity: 100% Ultrasonic Testing (UT) on primary structural load-bearing welds and drive-stand supports per AWS D1.1 standards.

Sprocket and Roller Metallurgy: Drive sprockets forged from 40Cr steel, precision machined, and induction hardened to HRC 52-58 on tooth profiles to prevent wear.

Structural Steel Treatment: Shot-blasting to Sa 2.5 standard followed by epoxy zinc-rich primer and polyurethane topcoats (total dry film thickness >= 160 microns) for outdoor mine site corrosion resistance.

Factory Acceptance Testing (FAT): Continuous 4-hour dry run testing on the shop floor to verify chain tracking, drive torque draw, noise level (< 80 dBA), bearing operating temperatures, and seal tightness before dispatch.

Spare Parts and After-Sales Support

Our Factory

Q: How do you determine whether an apron feeder or a vibrating feeder is needed under a hopper?

A: Apron feeders are selected when material contains large, unbroken ore lumps (over 500 mm), when dump trucks discharge directly into the hopper, or when positive volumetric dosing is needed under high head loads. Vibrating feeders are suited for smaller feed sizes (under 500 mm) where fines removal via grizzly bars before crushing is required.

Q: What design measures prevent apron feeder pans from bending under heavy ore impact?

A: We place continuous longitudinal impact rails fitted with heavy rubber damping strips directly underneath the feeder flights in the dumping zone. This transfers impact loads away from the chain links and into the main structural frame. Pans are also forged with thick center ribs for structural stiffness.

Q: Can your factory manufacture replacement chain assemblies or pans for existing third-party feeders?

A: Yes. We manufacture drop-in replacement chains, sprockets, rollers, and pans based on customer drawings or field-measured pitch and mounting dimensions. We verify chain pitch, bolt hole spacing, and sprocket tooth profiles to match your existing equipment footprint.

Q: How do you handle belt tracking issues on long-distance overland conveyors?

A: Our conveyor structures incorporate self-aligning training idlers at designated intervals along both the carrying and return strands. Head and tail pulleys feature CNC-machined crown profiles, and drive stands include screw or gravity take-up units to maintain consistent belt tension under variable load conditions.

Q: What anti-corrosion treatments are applied for equipment installed in humid or coastal mining environments?

A: Structural steel members undergo shot blasting to Sa 2.5 cleanliness followed by a three-coat paint system: zinc-rich epoxy primer, epoxy intermediate coat, and aliphatic polyurethane finish. Fasteners are hot-dip galvanized or zinc-nickel plated to resist rust.

Q: What quality documentation is provided with the equipment package?

A: Every shipment includes a comprehensive Quality Dossier containing Raw Material Test Certificates (MTC), Non-Destructive Testing (NDT/UT) Reports for frame welds, Bearing and Gearbox Test Certificates, Shaft Alignment Records, Paint Thickness Logs, and the Factory Acceptance Test (FAT) sign-off sheet.
