STEP 2 : calculate the air conveyor blower power. Outlet pressure = 0.35 bar g = 136325 Pa abs. Inlet pressure = 0 bar g = 101325 Pa abs. Power = 165 * 0.1338 * ln 136325/101325 = 6.55 kW. The pneumatic conveying blower needs to deliver 6.55 kW. Warning : this is not including efficiencies that need to considered on top of that.

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 ...

May 05, 2021· Calculation of Torque of Screw Conveyors. Full Motor Torque is the maximum torque exerted by the drive unit. The equation for full Motor Torque is shown below: Nomenclature: HP = Nameplate Horsepower of the motor on the screw conveyor. S = Conveyor Speed. Torque is measured in inch-lbs. for screw conveyor components.

an efficient means of transmitting power since it was invented by Hans Renold in 1880. Later the principle was applied to conveyor chain giving the same advantages of precision, heat-treated components to resist wear, high strength to weight ratio and high mechanical efficiency. Renold conveyor chain is made up of a series of inner and outer links.
