Work out conveyor capacity instantly with clear inputs, formula shown and shareable results.
Conveyor capacity is the load cross-sectional area times belt speed times bulk density. Cross-section depends on belt width, idler trough angle and the material's surcharge angle, which governs how high it heaps. Free-flowing material with a low surcharge angle carries less on the same belt.
Conveyor capacity
Capacity (t/h) = cross-section (m2) x speed (m/s) x bulk density (kg/m3) x 3600 / 1000
Conveyors present entanglement and nip point hazards. Guarding, emergency stops and lock-out procedures must comply with the applicable machinery safety standard.
Material degradation, dust generation, belt wear and spillage at transfer points. Typical mining speeds are 2-5 m/s; fine dusty material and fragile products need lower speeds.
Substantially. Moving from a 20 degree to a 35 degree three-roll trough can increase capacity by 25-30% on the same belt width, at the cost of higher belt stress and idler complexity.
