Black Heavy Duty Industrial Rubber Conveyor Belt For Bucket Elevator Conveyor System
The steel cord rubber conveyor belt is a high-performance, heavy-duty conveyor belt designed for long-distance, high-tension, and large-capacity material handling applications. Its core distinguishing feature is the use of steel cables as the primary tensile member, unlike traditional belts that use fabric plies (like polyester or nylon).
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

FAQ
Q1: How soon can we get a reply after we send you an inquiry?
A: The reply will be made within 2 hours after receiving the inquiry.
Q2: Are you a direct manufacturer or a trading company?
A: We have our own factory and international trade department, handling both production and sales directly.
Q3: What products can you provide?
A: We produce ST cord conveyor belts, sensor conveyor belts, pip conveyor belts, anti-tear conveyor belts, EPDM conveyor belts, high temperature resistant conveyor belts, heat resistant conveyor belts, fire resistant conveyor belts, EP conveyor belts, NN conveyor belts, SW fabric conveyor belts, cotton conveyor belts, chevron conveyor belts, rough top conveyor belts, oil resistant conveyor belts, chemical resistant conveyor belts, flat transmission belts, and rubber V belts.
Q4: What application fields are your products mainly involved in?
A: Primarily used for transportation tasks in metallurgy, chemical, cement, coking, steel and other industrial sectors.
Q5:What is the best way to store conveyor belts?
A: Conveyor belts should be stored in a cool, dry, and dark place, away from direct sunlight, rain, and chemicals. They should be kept in a rolled position (not folded) to prevent cracking or damage to the core. Avoid placing heavy objects on top of the rolls.
Q6:How does your company guarantee product quality?
A: We maintain complete physical and chemical testing equipment with a dedicated quality management team. All properties are controlled from raw material analysis through semi-finished products to finished product testing.
Q7:Can you customize the size and specifications of the belts?
A:Yes. We offer customized solutions based on your requirements. You can specify thewidth, length, cover thickness, color, and rubber properties(such as heat-resistant, oil-resistant, or flame-retardant) to match your specific conveyor system.
Q8: How to deliver goods to customers?
A: We primarily ship by sea from Qingdao port for convenience. For urgent shipments, air transport is available through the nearby international airport.
