Conveyor belts are basically very wide belts attached in a loop to two or more turning rotors driven by motors. The loop is the actual conveyor belt, and is generally made of two or more layers of rubber, one layer to give shape and structure to the belt and one to allow it to transport its load safely.
The entire four-flight direct drive conveyor system spans 10,632 m in length with the largest flight being 3,942 m long. At the time, this was the largest gearless drive conveyor in the world. The 1,800 mm wide belt conveyors, travelling at 6.4 m/s, move copper ore at a rate of 12,550 t/h.
Your mining operation relies heavily on conveyor belts to transport the material taken out of the ground and get it into production, so the durability and efficiency of your equipment is critical.Unscheduled downtime is unacceptable, and fugitive material is not only a maintenance and cleanliness issue – it represents lost profit.
"These conveyor systems are an efficient alternative to costly truck fleets. Also with deeper mines, the use of diesel driven trucks becomes more difficult. Another trend is in underground mining, where conveyors are an efficient alternative to drift hoists or dedicated rail systems.
A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types of conveyor systems.A belt conveyor system consists of two or more pulleys (sometimes referred to as drums), with an endless loop of carrying medium—the conveyor belt—that rotates about them. One or both of the pulleys are powered, moving the belt ...
