Screw conveyor design calculation - an Engineering Guide

Warning : It must be noted that those formula aim at giving an idea of the size of the screw conveyor (which means its diameter) and the speed at which it will operate, based on some assumptions and some design decisions (choice of screw pitch, inclination). The formula can also be used to roughly check the capacity of an existing screw feeder. They are not meant for a detail design and for ...

How to calculate motor drive torque for ball screws

18/05/2016  (In ball screw terminology, we commonly refer to lead, which is the linear distance the screw moves for every complete rotation, rather than pitch, which is the linear distance between screw threads.) The equation for drive torque: Td = (Fa * P)/(2000 * π * η) demonstrates that torque, T, is directly proportional to the lead of the screw, P. Danielle Collins says. September 28, 2018 at 12:33 ...
