Rotary screen is a kind of equipment commonly used in beneficiation. Through the continuous rotation of the screen body, large pieces of waste rock can be thrown out, greatly improving the next separation operation. When the roller screen works, the motor connects the reducer with the roller device through the coupling, and drives the roller device to rotate around its axis. The materials are turned over and rolled, and the materials are screened out one by one through different meshes. The materials stuck in the mesh can also be ejected to prevent blocking.
Operating principle of rotary screenThe drum device is installed on the rack obliquely, and is composed of motor, reducer, drum device, rack, screen and inlet and outlet. The motor is connected with the roller device through the coupling through the reducer, and the roller device is driven to rotate around its axis. When the material enters the drum device, due to the inclination and rotation of the drum device, the material on the screen surface will be turned over and rolled, so that the qualified material (products under screen) will be discharged through the discharge port at the bottom of the rear end of the drum, and the unqualified material (products on screen) will be discharged through the discharge port at the tail of the drum. Due to the overturning and rolling of the material in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from blocking. The principle and structure of the roller screen are almost the same as that of the roller screen, which is due to the difference in people’s understanding and nomenclature.
1.The mesh is not easy to block.
2.Stable operation and low noise.
3.Working principle and structure of roller screen: simple structure and convenient maintenance.
4.The screening cylinder can be closed, which is easy to close and collect dust.
5.The whole machine has high reliability and less one-time investment.
6.Special screen is adopted, with high screening efficiency and long service life.
