Chain conveyors

Chain conveyors can be used for handling a variety of free flowing material including sugar, grain, corn, coffee, beans, rice, flour, rape seed, soya, corn meal, garden seeds, peas, sunflower seeds, peanuts and even sawdust. It moves material quickly, efficiently and with minimum damage. Material is fed past the upper return chain. It then falls into the trough bottom, where the lower chain moves it and forwards to the discharge side. When the additional material is introduced, it lies on top of the moving material and is conveyed towards the discharge at the same rate as the chain. Drag chains carry the grains along entire depth of conveyor on special UHMWPE liners at an equal discharge rate and thus most of the material is gently carried on other layer of material. Plugging is eliminated as return chain limits the material to maximum level. In case, there is overflow of material at discharge end, built-in overflow device throws it out and if it is beyond acceptable limit, the limit switch stops the motor. Moreover, for any reason, if speed of the motor varies beyond tolerance limit, the sensor probe at tail end immediately gives signal to zero speed switch and the switch stops the motor, thus assuring complete safe operation.
