Conveyor belts for use in the underground coal mines of the U.S. must be flame resistant. The test for flame resistance is the SSFT as mentioned in preceding sections. Generally, conveyor belts are made from a rubber or plastic compound combined with one or more layers of fabric material or different diameters of steel cables. A conveyor belt may be made from polyvinyl chloride and fabric such

A conveyor belt at a coal mine became loose, ran askew and material was adhering to the corrective roller. This misalignment caused the belt edges to wear, reduced the life of the belt and increased spillage along the conveyor. These problems not only impacted the material handling efficiency but also increased the labor intensity, and created serious environmental pollution. Read Case Study

Belt conveyors consist of two powered pulleys with a continuous loop of belting material used to convey products. Belt conveyors are the most economical powered conveyor and are typically used for conveying products over long distances, at high speeds, or for incline/decline applications. This is done with endless procession of hooks, gears, buckets, and a wide rubber belt. The belt is then

Before starting conveyor belt system it is necessary to start first receiving conveyor and then start feeding conveyor i.e. operating logic is from down stream to upstream. For stopping of conveyor system the operation will be opposite i.e. from upstream to down stream. So it is necessary if any conveyor is stopped in the system all the upstream conveyor should stop automatically. The existing

29.05.2020· Conveyors consist of a set of pulleys that control a belt made from rubber, chain, and other materials. In a coal mine, workers can dump loads onto a conveyor for movement out of the facility and delivery to trucks or a processing area. The coal conveyor belt carries raw coal and other components continuously, and may be quicker and more efficient than trucking the coal out in carts.
