Trommel screen is a kind of machine which is widely used in separation technology. It can control the separation of garbage by controlling the particle size and has high separation accuracy. The cylinder body of the drum screen is generally divided into several sections, which can be determined according to the specific situation. The screen holes are arranged from small to large, and the aperture of each section is the same.LDHB is a professional mining machinery which supplies polyurethane trommel screens in South Africa.
The LDHB drum rotary screen is mainly composed of motor, reducer, drum device, frame, sealing cover and inlet and outlet.
Drum rotary screen is a kind of machine widely used in separation technology. It controls the separation of garbage by controlling the particle size and has high separation accuracy. The cylinder body of the drum screen is generally divided into several sections, which can be determined according to the specific situation. The screen holes are arranged from small to large, and the aperture of each section is the same. In order to improve the separation accuracy, in order to avoid the small particles being screened out in the large aperture screen, the garbage must be turned over fully in the roller screen, and the moving speed of the garbage should not be too fast. Generally, the inner wall of the drum is equipped with a deflector. Its function is to lift the garbage particles, so that the garbage particles of different sizes can contact the screen hole as much as possible. If the requirements of the pore size are met, the particles can pass through the screen to achieve the separation purpose of the drum screen.
In order to improve the screening efficiency, the speed of garbage moving in the roller screen should not be too fast, otherwise the screening will be incomplete and incomplete. Therefore, generally speaking, the installation angle of the roller screen is strictly regulated, which is 5 ° generally. Of course, in actual situation, it can be adjusted according to the needs.
