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.

From this I calculate the torque to be 6.2 kN and using an efficiency factor of 0.85 the power needed would be 3.0 kW. The driving force is provided by forcing the smooth surface of a grooved transmission belt, driven by the motor, against the surface of the chain block over a distance of 1.2mtr.

To calculate the belt length, you would typically use the following formula: Belt Length = ( (Diameter of Drive Pulley x π) + (Diameter of Tail Pulley x π) / 2) + (2 x Center-to-Center distance between pulleys) + (Belt Sag x 2). This formula may vary slightly based on the conveyor design.

To calculate the speed of a conveyor belt in feet per minute, a specific formula is used: See also Stone Tonnage Calculator Online. Speed (ft/min) = (π/2) * Drive pulley diameter (ft) * RPM / 60. where: π (pi) is a mathematical constant approximately equal to 3.14159. Drive pulley diameter (ft) is the diameter of the drive pulley in feet.

The Formula. There is a reliable formula for working out the speed of your belt, and it looks like this: · Speed = roller circumference x motor RPM (revolutions per minute) However, if you have a gear reduction system in place, you'll need to factor this into the equation. For example, if your gear ratio is 20:1, you'll need to divide the ...
