All About Roller Conveyors - Types, Design, and Uses

The biggest innovation is the drive or live roller conveyor, where each roller is connected to a motor via a belt/chain/shaft to increase controllability. This equalizes the rate with which materials move down the pathway, and also allows these conveyors to have limited use in reverse, i.e. from low to high elevation.

A Simple Guide to Conveyor Drive Types | mk North America

In a direct drive configuration, the motor directly powers the drive roller of the conveyor. With an indirect drive, the motor is mounted remotely of the drive pulley (often below, but it can be above or to the side of the conveyor) and a series of gears or sprockets and chain or timing belts transmits the power form the motor to the drive roller.

How to Measure a Conveyor Belt: Center-to-Center Distance ...

The math is not as difficult as it appears. Here's the logic behind the center-to-center distance formula: 2C: Multiplying the center-to-center distance by 2 accounts for the belt length on the top and bottom of the pulleys Note: The pitch created by differing pulley diameters is addressed later in the equation. (D+d ÷ 2): This accounts for the belt length "wrapped around" the outer ...
