Steep angle belt conveyor

The steep angle belt conveyor is specifically designed for bulk material transportation in complex terrains. Utilizing a deep-trough structure combined with high-friction retention technology, it achieves stable transportation within an inclination range of 0° to +30°. Certified by ISO 9001/CE and compliant with DTIIA/TD75/CEMA international standards, this equipment seamlessly integrates with industrial machinery such as crushers, screening machines, and stacker-reclaimers. It is widely applied in mining, ports, metallurgy, and other industries for bulk material handling, with a maximum capacity of 15,000 m³/h and the ability to transport lump materials up to 300mm in size.

Technical Specifications

Typical Application Scenarios

Mining Ore Transportation

Designed for long-distance transportation from open-pit mines to processing plants and stockyards, the steep angle belt conveyor navigates 28° slopes and canyon terrains. Configured with deep-trough buffer roller sets, it carries lump ores ≤350mm and withstands 2.5× rated impact loads. Flywheel energy storage units integrated in high-drop zones recover 18-25% braking energy. Combined with permanent magnet synchronous motors, overall energy consumption is reduced by 30% compared to traditional systems. Steel trusses use Q355B weather-resistant steel and hot-dip galvanizing for a 20-year lifespan.

Port Bulk Cargo Handling

In 10,000-ton bulk terminals, the system achieves integrated ship-to-shore and yard operations. Fully enclosed chutes with negative-pressure dust control maintain PM10 levels ≤5mg/m³, complying with GB16297 standards. Vector frequency control adapts to tidal load fluctuations, achieving 6,000t/h handling efficiency. Critical components use 316L stainless steel, validated for >15-year corrosion resistance in coastal environments.

Aggregate Material Conveying

For graded material transport from quarries to mixing plants, anti-segregation feeders and ceramic-coated rollers reduce fine particle (<5mm) residue to <0.3kg/100m. Acoustic cleaning devices in sealed sections and double-layer noise enclosures limit operational noise to 75dB(A), meeting urban construction requirements. Low-temperature models operate stably at -30°C with electric heating to prevent belt icing.

Power Plant Fuel Transportation

In coal-fired plants, the conveyor enables fully enclosed transport from unloading pits to bunkers. Integrated metal detectors, magnetic separators, and flame-retardant belts (oxygen index ≥32%) enable millisecond-level fire suppression via spark monitoring. Cold-region models feature drum heaters and insulated galleries to prevent frozen coal blockages, with real-time calorific value tracking through fuel management platforms.

Cement Raw Material Transport

In limestone mining-to-plant systems, a single 12km conveyor replaces multiple transfer points, reducing material loss by 40%. Multi-stage buffer airlocks and ceramic-lined chutes eliminate dust at elevation drops. Al₂O₃ ceramic-embedded pulleys achieve 50,000-hour service life, tripling standard rubber-lagged models. DCS integration enables ±2% production fluctuation compensation through raw mill coordination.
