A roller screen is also called trommel screen and drum screen.The roller screen with shaft is a special screening equipment developed for power plant, coking plant, building materials, metallurgy, chemical industry, mining and other industries. It overcomes the screen sticking and blocking problems of various vibrating screens when screening wet materials, and improves the output and reliability of the screening system. It is suitable for screening materials of various properties, as well as damp and easily blocked materials such as coal, coal gangue, coke, quicklime, etc.
The drum screen is equipped with broken bag props inside, which is reliable without winding. Shaftless drum screening machine is an important screening equipment in waste treatment line.
The drum unit is tilted to the frame. The motor is connected with the drum device through coupling through the reducer, and the driving roller device rotates around its axis. When the material enters the drum body, the material on the screen surface is turned over and rolled due to the tilt and rotation of the drum device. So that the qualified materials- material size is smaller than the screen size (products under screen) are discharged through the discharge port at the bottom of the back end of the drum. And the unqualified materials – material size is larger than the screen size(products on screen) are discharged through the discharge port at the end of the drum. Due to the material turning and rolling in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from blocking. The principle structure of roller sand screen, drum screen separator and roller screen is almost the same, which is the difference of people’s understanding and calling.
