Power calculation of the screw conveyor. Now we need to calculate the drive power of the screw conveyor. This is important to select the motor, shaft, and bearings. The drive power of the loaded screw conveyor is given by the formula: P H = Power required for the material's progression.
Screw conveyors, like any other mechanical equipment, are driven by an electric motor.The motor provides a lot of power (HP) but very little torque (In-lbs). The power is effective at conveying the bulk material in the screw conveyor but can do little to start the screw or rotate it.
Step 1 : define the requirement. Define the capacity required for the screw conveyor. The design of the screw must reach a capacity equal or greater than this value. Example : …
Calculation of Conveyor Speed. Conveyor Speed can be most conveniently calculated, by use of the nomographs supplied on pages. To use this nomograph – first locate the two known values (screw diameter, and required capacity, in cu. ft. per hour), then with a straight edge connect these two points.
Ƞ2 ) PROBLEMS ASSOCIATED WITH INCLINED SCREW CONVEYOR Several things can be done to overcome many of the problems associated with inclined screw conveyor : 1 Limit the use of standard screw components to inclines of less than 25⁰, preferably not over 15⁰. 2 Use close clearance between trough and screw 3 Increase the speed over that ...
