Engineered for high-temperature, heavy-load, continuous operation in cement plants, QBF rubber bucket elevator conveyor belts solve persistent field issues including belt tearing, heat degradation, and unstable installation. Through innovative rubber compounding and structural design, our belts deliver reliable vertical lifting for cement clinker, raw meal, and other hot bulk materials.

Precision Compounding & Curing for Consistent Quality
      Our fully automated internal mixing center ensures batch-to-batch consistency in heat-resistant rubber formulation. The intelligent curing line enables one-stage vulcanization under controlled temperature and pressure, producing strong interlayer adhesion and stable dimensions critical for long-term reliability.

Rope-Free Steel Cord Zone Eliminates Joint Stress

Conventional joint drilling often damages steel cords and creates stress points that accelerate belt failure. Our rope-free zone design retains high-toughness rubber at the joint, eliminating wire breakage risk while maintaining full tensile strength in load-bearing areas. This design improves installation flexibility and extends service life.

Precision Punching & Dedicated Clamp Kits

Automated high-precision punching ensures accurate hole spacing and alignment, preventing bolt loosening, bucket deviation, and uneven wear—essential for 24/7 cement plant schedules. Complementing this, our custom-engineered clamp kits provide uniform clamping pressure, effectively dispersing impact loads and tension to prevent hole-edge tearing and bucket detachment, while simplifying installation and maintenance.

Full Product Range & Customization

Available in fabric-core and steel-cord constructions, with heat resistance from 100°C to180°C, plus oil-resistant and flame-retardant options. Our team offers application-specific selection and design support to match your exact operating conditions.
