Conveyor belt can cost-effectively transport all kinds of materials, conveyor belt in the environment temperature -20 ℃ to +40 ℃ range, the temperature of the material transported below 50 ℃. In industrial production, the belt conveyor can be used as production machinery and equipment constitute a continuous production of a link between, in order to achieve continuity of production processes and automation to improve productivity and reduce labor intensity. Friction drive belt according to the principle of their movement, with a transmission capacity, transmission distance is long, smooth transportation, materials and there is no relative motion conveyor, less noise, simple structure, easy maintenance, energy consumption, standard parts, etc.which are widely used in mining, metallurgy, chemical, foundry, building materials industry, transport and production lines, and hydropower construction sites and ports and other production sectors, used to transport loose materials or items.
