1. Calculate the drive torque. T AN. ACCORDING TO TORQUE 2. Base the coupling rated torque T KN on the drive torque T AN multiplied by the application factor. (see page 17 for shock or load factors S A). T KN ≥ T AN · S A Example: Coupling between an electric motor (P=1000kW and n=980 rpm) and a gearbox driving a screw conveyor (S A = 1.6).

Screw Conveyor] refer below to Table No. 1, "Size of Lumps to Diameter". If the required diameter (as found above] is smaller than the recommended size given in the Lump Chart, use the conveyor diameter from the chart Table #1 and then determine the RPM from Table #7.

Note: High starting torque motors must not be used without design verification by Kase''s Engineering Department. Example: A 12-inch carbon steel conveyor has been selected with a required shaft horsepower of 8.9 and a speed of 64 RPM. The drive to be used has an efficiency of 85%, thus requiring a drive input of 10.46 horsepower. Therefore, a 15 horsepower motor must be used.

· Calculate Horsepower For Inclined Screw Conveyors Screw conveyors can be used to convey bulk materials at an inclined angle, but several areas of design should be examined first. Because of the incline of the screw, several conveying problems begin to occur. 1. The horsepower per unit of material increases

· Calculation For Motor Power Of Screw Conveyor. To insure adequate torque capacities without undue additional cost, means are provided in the industrial standard series of conveyor components for more than one maximum allowable horsepower value.This is accomplished by not only a choice of power-transmitting component sizes but also of the materials of construction.

· If I ever need to calculate approximate conveyor power, for example on simple in-plant inclined conveyors, I often do the following simple calculation. Power = t/h x lift x 2.72 x 1.3 kW From this you can easily calculate the torque, if you have the speed and pulley diameter from the following: Torque = 9.55 x power divided by pulley rpm kN-m
