Heavy Duty Bucket Elevator Conveyor Belt for Cement Mining And Coal Conveyor System
Steel Cord Heavy Duty Bucket Elevator Conveyor Belt is a high-performance, heavy-density conveyor belt specifically engineered for vertical bucket elevators handling large volumes of bulk materials under severe working conditions. Featuring high-tensile steel cord as the load-bearing carcass combined with high-quality rubber covers, this belt is ideal for heavy-load, high-lift, and long-service-life conveying applications.
Product Structure
The belt consists of three main components:
- Steel cord tensile layer: High-strength, low-elongation steel cords arranged longitudinally to bear major tension
- Top and bottom rubber covers: Wear-resistant, impact-resistant rubber compound to protect the steel cord and resist abrasion
- Intermediate rubber: Ensures firm adhesion between steel cords and rubber layers, preventing delamination
Key Features
- High tensile strength for heavy-duty applications
- Excellent impact resistance and long service life
- Minimal elongation during operation
- Superior slotting properties and bending flexibility
- Ideal for long-distance, high-speed material transportation
This product is widely used in coal mining, ports, metallurgy, power generation, chemical processing, and various industrial fields for efficient material transport.
