Motor Sizing Basics Part 1: How to Calculate Load Torque

To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm. Typically, a safety factor is used so that the ...

Prevent Conveyor Carryback With Belt Scrapers

A multiple-cleaner system has been proven one of the most effective ways to prevent carryback.

Conveyor Belt Support with Idlers

The basic means of support for a conveyor belt is idlers. An idler consists of one or more rollers – with each roller containing one or more bearings to ensure it is free rolling. The rollers are supported by, or suspended from, a framework installed across the conveyor stringers. Idlers are the most numerous of conveyor components, in terms ...

Why install a belt turnover system?

Mordstein belt turnovers are designed for wide steel cable belts (around 72" to 96" wide). The objective of this type of belt turnovers is to support the weight of belt during is twisting transition to minimize sagging and to avoid buckling. The major down sides to the Mordstein method are these systems are highly complicated, difficult ...
