Trommel screen gold washing plant

Description Representing a new generation of sieving equipment, the trommel screen has effectively overcome the blocking problems of the circular and linear vibrating screen when screening the wet materials, which has improved the productivity and reliability of the whole screening process. There are various kinds of trommel screen available: >> Stationary type, mobile type >> Small scale type, large scale type >> Motor engine type, diesel engine type >> Single layer type, double layer type Structure The trommel screen is consist of mainly 6 parts which are cylinder, main frame, discharging devices, reducer, electric motor / diesel engine, and flushing water device. Working Principle By using the mechanical design, GT trommel screen provides the efficient screening area by placing a number of grating bars side by side in which way the screening holes are formed. The screening is completed using the materials' self-weight while rotating. The three coupling shafts are designed higher than the screening surface, which enables the larger particles being stirred up and thus increases the screening efficiency. The particles larger than screen mesh size are discharged as the uppersize materials which could be delivered away by belt conveyor, while the particles smaller than screen mesh are discharged as undersize materials which could be fed into the following equipment.
