eng.conveyor-belt-power Calculator
Calculates belt conveyor power demand from capacity, conveyor length, lift, speed, and idler friction. Conveyor power has three components: belt drive friction, material lift power, and material acceleration power — idler friction dominates for long, flat conveyors.
Inputs
Q T Hr
Reference formula or conversion factor shown for context.
L M
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
H M
Vertical measurement. For health calculators, typically standing height without shoes.
V M S
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
Results
lifting power P_lift (kW)
Aerodynamic force perpendicular to the direction of motion. Lift = 0.5 × rho × v^2 × Cl × A. Enables flight when it exceeds weight.
friction power P_friction (kW)
Sample size or count used in the calculation.
total power P (kW)
The combined total across all inputs and components.
belt tension at drive (N)
The tensile force or stress — the pulling force that stretches the material. Must stay below the material's tensile strength.
P = Q·g·H + Q·g·L·f
Reference formula or conversion factor shown for context.
motor size recommendation (kW)
Suggested action or value based on the computed results and applicable best-practice guidelines.
