Consequently, stocking of coal has to be done consciously and by respecting basing rules. 2. Methods of Coal Stacking Produced coal is generally loaded in trucks or wagons by excavators and loaders to be transported then to the storage areas. Belt conveyor is another transportation alternative.

A typical conveyor belt scale or belt weigher system has a weigh bridge structure supported on load cells, an electronic integrator, and a belt speed sensor. The load cells measure the material weight on the belt, and send a signal to the integrator. The integrator also receives input in the form of electrical pulses from a belt speed sensor.

The speed of the coal sampler is crucial for the sampling procedure. According to some researches, the suggested sampler collector size is three times than the coal nominal top size, and the speed of the coal sampler should less than 1.5m/s. Central cross belt sampler is used to the coal moving stream which is installed on the coal conveyor ...

Operation of Conveyors • Various conveyors are provided for transporting the coal from Track hopper to Bunkers. • The following precautions are to be taken before taking any conveyor into service: • a) There is no oil leakage at gearboxes / fluid couplings and the oil levels are correct.

The movement of coal from face to gate usually includes a scraper chain loader with a fixed flexibility to the face and gate conveyors to ensure centralised transfer. Water, used to reduce dust to a minimum, tends to cause some of the coal fines to adhere to the return belt which can only be removed by the use of polyurethane, mild and hardened ...
