Trommel screens provide a simple, efficient and economical solution to upgrade a wide rang of material and optimize the subsequent process steps of recovery. This method of screening helps to reduce operating and investment cost and to increase product quality, while allowing rapid and large volume processing. Descriptions Material feeds into the drum, is lifted up by the rotation as it falls back down. This action is repeated with each revolution along the length of the drum. The finer material passes through the screen openings while the larger material tumbles towards its eventual exit at the rear of the drum. The trommel screens provide a simple, efficient and economical solution to upgrade a wide rang of material and optimize the subsequent process steps of recovery. This method of screening helps to reduce operating and investment cost and to increase product quality, while allowing rapid and large volume processing. This material is then passed on to the downstream process equipment which can be in various forms such as centrifugal concentrator, spirals, jigs etc. Advantages and characteristics 1 economical and efficient solution for screening; 2 heavy duty trommel drum with lifters at the front to facilitate material break up; 3 screen replaceable for different mesh sizes; 4 multilayer screens; 5 easily change screen plates; 6 high efficiency and big capacity; 7 unique screen design, result in higher capacities, longer screen life and no material clogging; 8 heavy duty feed hopper; 9 discharge chute; 10 gear drive mechanism.
