Equipment for screening coal - Coal flag coal separation drum screen

The working principle of the shale drum: The drum device is tiled and installed on the rack The electric motor is connected to the drum device through a reducer and a coupling, driving the drum device to rotate around its axis after the material enters the drum device, due to the tile and rotation of the drum device, The material on the screen surface flips and rolls Qualified materials (products under the screen) are discharged through the discharge port at the bottom of the rear end of the drum, while unqualified materials (products on the screen) are discharged through the discharge port at the tail of the drum

The drum screen is widely used in fields such as mining [quartz stone, cobblestone, silica, scale, Limestone, diamond, garnet, crushed stone, crushed stone, metal stone, etc.], chemical industry, metalurgy, coal mine [coal, bump coal, crushed coal, coal slide, raw coal, wet coal, water washed coal, etc.], cement plants, non metallic ore Raw material purification, The products are best selling at home and abroad, and the benefit process design has won practice from many customers!

Due to the different screening methods of vibrating screens and drum screens, the materials they are good at screening are also different The following is an introduction to the selection of sever screening machines for different production capacities and applicable cases:

(1) The drum screen has a large output and long service life, making it suitable for use with high production requirements When there are many or large stones in the material, and the visibility of the material is high, it is better to choose to use a vibrating screen due to the strong vibration force

(2) The linear vibrating screen has a small output and is suitable for screening fine sized materials The screening of materials with small particles and cost is the weakness of vibrating screens, and the screening effect of using a drum screen will be better

(3) The circular vibrating screen has a large output and is suitable for large production lines with high production requirements When screening dry materials, the use of vibrating screens is not easy to block holes, and the screening effect is better
