MWIN Steel Cord Conveyor Belt is a heavy duty, high performance rubber conveyor belt engineered for long distance, high tonnage, high tension bulk material handling. Manufactured by Qingdao MWIN Industry And Trade Co., Ltd. (Shandong, China), it is built to meet international standards (GB/T 9770, DIN 22131, AS 1333, JIS K 6369) and deliver exceptional reliability in mining, cement, coal, ports, metallurgy, and power generation.

MWIN steel cord belts feature a multi-layer composite structure optimized for extreme tensile loads and harsh operating conditions:

• Material: High-tensile, galvanized/brass-coated steel cords (e.g., K6×7+1WS, K6×19+1WS) for superior corrosion resistance and rubber adhesion
• Arrangement: Longitudinally parallel, evenly spaced cords with tension uniformity controlled to ±1% (far exceeding the industry standard of ±3%)
• Strength Range: Tensile strength from ST630 up to ST5400 kN/m, supporting spans of several kilometers
• Key Benefit: Provides near-zero elongation under load and exceptional resistance to flex fatigue

• Core Rubber: High-adhesion rubber matrix that fully encapsulates and bonds to steel cords, preventing delamination and cord corrosion
• Top Cover Rubber: Wear-resistant, impact-absorbing compound (abrasion loss: 70-300 mm³) to withstand heavy, abrasive bulk materials
• Bottom Cover Rubber: Low-rolling-resistance rubber for efficient power transmission on pulleys and idlers
• Edge Rubber: Reinforced side rubber to protect against edge tearing and environmental ingress

MWIN offers specialized constructions for demanding applications:

• Standard Type: General-purpose for most heavy-duty conveying
• Rip-Resistant Type: Embedded transverse steel cords or anti-tear sensors to prevent catastrophic longitudinal tearing
• Impact-Resistant Type: Thickened top cover and shock-absorbing core for high-drop, coarse material handling
• Fire-Retardant Type: Complies with MT147/MT668 for underground mining and high-fire-risk zones

1. Extreme Tensile Strength: Handles the highest tension loads for long-distance, single-flight conveying without intermediate drives
2. Minimal Elongation: Requires very short take-up travel and maintains consistent tension, reducing downtime and maintenance
3. Superior Adhesion: Steel cords are fully bonded to rubber, eliminating cord pull-out and extending service life
4. Excellent Flex Fatigue Resistance: Performs reliably around small-diameter pulleys, enabling compact conveyor design
5. Outstanding Impact & Tear Resistance: Absorbs heavy impacts and resists cutting from sharp materials
6. Uniform Tension Distribution: Balanced cord layout prevents belt wandering, edge wear, and premature failure
7. Versatile Environmental Resistance: Available in fire-retardant, heat-resistant, cold-resistant, oil-resistant, and acid/alkali-resistant grades
8. Easy Splicing & Repair: Compatible with mechanical clamps and vulcanized splices for fast field maintenance

MWIN Steel Cord Conveyor Belts are the preferred choice for:

• Mining: Coal, iron ore, copper, bauxite, and aggregates
• Cement & Building Materials: Clinker, limestone, gypsum, and raw materials
• Ports & Terminals: Long-distance ship loading/unloading of bulk cargo
• Power Plants: Coal and ash handling
• Metallurgy: Sinter, ore, and slag conveyance
• Quarries & Aggregates: High-abrasion stone and gravel transport
