Belt conveyors are used for carrying coal ores and minerals .

Belt conveyors are used for carrying coal, ores and minerals in power plants, mining industries, and metallurgical process plants. Capacity of a belt conveyor system may range from 500 to 5000 m 3 /hr and more. The distance covered for a belt conveyor system may be as small as 50 m to 5km for supplying material from mine area.

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 technical look at conveyors - Canadian Mining .

In 1892, Thomas Robins began a series of inventions which led to the development of a conveyor belt used for carrying coal, ores and other products. In 1901, Sandvik invented and started the production of steel conveyor belts, and in 1905, Richard Sutcliffe invented the first conveyor belts for use in coal mines which revolutionized the mining .

How To Choose A Mining Conveyor Belt - Mining Technology .

Conveyors running underground or transporting material from mines and quarries are posing greater demands on the conveyor belt than a line in a factory transporting empty boxes. Understand your needs when it comes to durability and ruggedness. Failure to consider this could result in productivity loss and increased downtime. Corrosion-resistance
