horsepower calculation for shaftless screw conveyor


Dragon-Flite Drag Conveyor Horsepower Calculation

The Live Horsepower is the power required to overcome the friction of the material sliding along the bottom of the housing over the length of the conveyor. Live HP can be calculated using the following formula. HPL = Live Horsepower Requirement Wm = Weight per foot of Material Being Conveyed Lb/ft

Finding the Best Screw Conveyor Horsepower - JMS

Once it has been determined that a Screw Conveyor will best fit your appli ion and the type of screw conveyor you will use shafted or shaftless a calculation will be completed to specify the horsepower that will be needed to meet the needs of the appli ion. Simply put horsepower is a measure of the rate at which work is done.


Screw Conveyor Engineering Guide Shaftless Screw Conveyors Bulk materials discharged from centrifuges filter presses or mixers can easily be conveyed using a KWS Shaftless Screw Conveyor. Our shaftless design provides a non-clogging conveying surface that allows difficult-to-convey materials to become easy-to-convey. The Screw Conveyor. KWS

Screw Conveyor Engineering Guide - Horsepower Calculation

Assuming a drive efficiency of 85% resulting in a total drive horsepower of 1.853 a standard 2 horsepower motor would be selected for the drive input. The horsepower required for the above conveyor may also be determined graphically by the use of the two horsepower nomographs. The first nomograph determines Friction Horsepower.

Screw Conveyor Horsepower Engineering Guide

TSHP is the sum of Friction Horsepower and Material Horsepower divided by the drive efficiency. Friction Horsepower is the horsepower required to turn a screw conveyor when empty. Friction from the bearings seals and other moving components create resistance. Sufficient horsepower is required to overcome the friction.
