how to calculate power requirement for screw conveyor

Shaftless screw conveyor capacity is calculated using the spiral diameter, spiral pitch, trough loading percentage, degree of incline (if any) and spiral rotational speed. The required speed is then calculated by dividing the required material flow rate by the capacity per revolution. "D" and "d" are the outer and inner diameters of the ...

SC = 3.75 * 1.50 * 323. SC = 1817cu.ft. This selection capacity value will be used in the capacity table, for calculating correct size and speed. In the appropriate column, under 30% A loading, we find that a 14″ conveyor, at the maximum recommended speed will convey 2194 cu. ft. per hr. or 21.1 cu. ft. per revolution.

89 Belt Tension Calculations W b =weight of belt in pounds per foot of belt length. When the exact weight of the belt is not known, use average estimated belt weight (see Table 6-1) W m =weight of material, lbs per foot of belt length: Three multiplying factors, K t, K x, and K y, are used in calculations of three of the components of the effective belt tension, T

Primary considerations for the selection of a screw conveyor are: Type and condition of the bulk material to be conveyed including maximum particle size and specific bulk density.

In order to find the maximum tension is necessary to calculate the effective tension, that is, the force required to move the conveyor and the load at a constant speed. The calculation of the total tension is based on a constant speed of the belt including the necessary basic conditions to overcome the frictional resistance and tension forces.

There are many variations of Horse Power (HP) calculations found in historical and individual manufacturer's literature. The formulas below are used to determine the power requirements of a Bucket Elevator throughout the industry. Equation 1 – Power Formula. A basic power calculation is the measure of force over a distance per time period.

Empty HP. The Empty Horsepower is the power required to overcome the friction in the power transmission system, chain/sprockets, and the flights dragging on the bottom of the trough. Empty HP can be calculated using the following formula. HPE = Empty Horsepower Requirement. Wc = Weight per foot of Chain and Flight (Lb/ft) L = Length of the ...
