Heavy duty rock trommel screen working principle
July.15,2025
The ore drum screen is generally composed of a drum, a frame, a funnel, a reducer and an electric motor. In addition, different placement schemes can be designed for the equipment based on the production needs of the customer. When the mining drum screen is working, the crushed ore enters the drum from the feeding end. On the one hand, it will be affected by the centrifugal force generated by the rotation of the drum, and on the other hand, it will be affected by the jigging effect. The ore with a relatively large particle size will flow forward along the inclination of the drum. The ore with a suitable particle size will be screened out in turn according to the specifications when passing through the screen and fall into their respective funnels, and finally sent to the finished product pile by the belt conveyor.
