Above 45-degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the KWS Engineering Guide for Vertical Screw Conveyors. As the degree of incline increases, conveying efficiency is reduced and horsepower requirements increase due to the effects of gravity and bulk material fall back.

Save time by utilizing our Horizontal Screw Conveyor Calculator to accurately determine screw conveyor size, horsepower, and RPM requirements in a few easy clicks. Send your calculations directly to KWS engineers for review and …

Horsepower Requirement for Inclined Screw Conveyor Calculator. Power Requirement in Horizontal Position (HPh): Inclination of the Screw (α): Horsepower Requirement for Inclined Screw Conveyor Formula. Horsepower (( HPi )): [ HPi = HPh cdot sin(alpha) ] Where:

This document provides guidance on calculating the horsepower required for screw conveyors. There are two main types of horsepower to calculate: friction horsepower (FHP), which is the power to drive the empty conveyor, and material horsepower (MHP), which is the power to move the material. Total shaft horsepower (TSHP) is calculated by adding FHP and MHP. FHP and …

The calculations recommend a 20 inch diameter screw conveyor running at 33.3 revolutions per minute with a total horsepower requirement to overcome friction and lift the material. 1. This document provides calculations for designing a 250 ton per hour screw conveyor to transport material horizontally from a chute to a bin that are 30 meters apart.
