How do you calculate belt force? Belt force, or tension, can be calculated using the following formula: T = (μ × Fg) + (m × a) T is the tension or force in the belt (N), μ is the coefficient of friction between the belt and the material or rollers, Fg is the gravitational force of the load and belt, which is the mass (m) times the acceleration due …

Belt Pull = Total Weight x frictional coefficient. Belt Pull = 280 lbs x 0.5. Belt Pull = 140 lbs. Then, convert this to required power. Required Power = Belt Pull x Belt Speed. Required Power = 140 lbs x 50 fpm = 7,000 ft-lbs/min. Convert that to a useful unit of measure. One horsepower (HP) equals 33,000 ft-lbs/min.

To calculate the speed of a conveyor belt in feet per minute, a specific formula is used: See also Stone Tonnage Calculator Online.
