Sizing a conveyor drive motor and not sure if your belt can handle the load? Conveyor Belt Power Calc uses CEMA-standard formulas to calculate belt speed, capacity, effective tension, and required horsepower — so you spec the right motor the first time.
Select belt width, material type, conveyor length, lift height, and trough angle. Get instant results for belt capacity (tons/hr), effective tension (lbf), belt horsepower, and total power including drive losses.
CEMA-BASED CALCULATIONS:
- Effective tension: Te = L x f x (Wm + Wb) + H x Wm
- Belt power: HP = Te x V / 33000
- 10% drive loss factor included
- Capacity scaled by speed and trough angle
BELT WIDTHS:
- 18" through 96" standard widths
- CEMA capacity table at 100 ft/min baseline
- Belt weight per foot for each width
MATERIAL DATABASE:
- Dry sand and gravel, coal, crushed stone, iron ore
- Grain, wood chips, limestone, wet earth
- Friction factors per material type
TROUGH ANGLES:
- 20, 35, and 45 degree idler options
- Capacity multiplier per angle
QUICK CALC AND DETAILED MODES:
- Quick Calc for fast field estimates
- Detailed mode for full engineering inputs
