Conveyor belts resemble a band or loop of rollers connected to rotors powered by a motor. The belts can be as narrow as one inch (25 mm) or as wide as five feet (1.5 m), with plastic modular belts as wide as ten feet (3 m). Conveyor belts are made of highly durable and sturdy materials, much like heavy-duty machinery.

Key Function. Before we look directly at the workings of a conveyor belt, we need to understand what they've been designed to do. A conveyor belt is an automation process: it enables a machine to perform the role of multiple human laborers in delivering materials or goods from one location to another. As such, this is the major, basic ...

Coal flow in belt conveyors is often mixed with foreign objects, such as anchor rods, angle irons, wooden bars, gangue, and large coal chunks, leading to belt tearing, blockages at transfer points, or even belt breakage. Fast and effective detection of these foreign objects is vital to ensure belt conveyors' safe and smooth operation. This …
