Conveyor Belt Power Calc

Professional field calculator for trades professionals.

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
