You desire your conveyor to operate at 90 Feet Per Minute. Calculate as follows: (1/2 X 90) / 65 = .69. You should select the next highest horsepower or 3/4 Hp. This formula should provide you with a good estimate, but it's always best to confirm it with conveyor experts. Ask us to do a complete horsepower calculation if this causes any concerns.

1 HP = 0.746 kilowatts = 0.746 kW. A previous Rulmeca video showed how a 150 foot long conveyor with a 30 inch wide belt and a 10 HP drive system, originally installed to carry 575 tons per hour (tph) at 300 fpm, could be upgraded to handle 800 tph. Option one recommended that the conveyor be fully skirted while maintaining a 300 fpm belt speed.

Equation 6 – Bucket Elevator Power Formula – Friction Factor Method. Another way to account for the system friction is to add a multiplication factor to the calculated HP in Equation 3. This multiplication factor typically ranges from 10% to 30%, depending on the application. Consult your Bucket Elevator Supplier for additional information.

The basics of the Calculations of Conveyor Belt Design Parameters. Belt tension: The belt of the conveyor always experience a tensile load due to the rotation of the electric drive, weight of the conveyed materials, and due to the idlers. The belt tension at steady state can be calculated as: Tb = 1.37*f*L*g*[2*mi+ (2* + mm)*cos (δ)] + (H*g ...

Assuming that the pulleys have diameters of 6 and 20 inches, you need a belt that's exactly 153.72 inches. To find that number on your own, you need to use the belt length formula: Belt length = π/2 × (DL + DS) + 2L + (DL - DS)2/ (4L), where: DL is the diameter of the larger pulley (here 20 inches); DS is the diameter of the smaller pulley ...

Horsepower is defined as the power required to safely and feasibly convey a bulk material a fixed distance in a screw conveyor. The horsepower required to drive a screw conveyor is called Total Shaft Horsepower, or TSHP. TSHP is a function of the characteristics of the bulk material being conveyed and the friction inherent in the screw conveyor ...

In order to calculate horsepower, it is necessary to determine the resultant force (R) due to the weight (W) acting at incline angle (a) Force (R) equals Weight (W) multiplied by sine (a). Sines of common incline angles are listed in weights and tables. The force (T) required to move the load is the sum of the resultant force (R), plus the ...

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.
