As the cylindrical drum of the rotary trommel screen rotates, the raw material is lifted on the rack until it is close to the top of the drum. Then， the material falls onto other materials at the bottom of the drum. Furthermore， the small particles are filtered through the screen in the continuous rolling process when the larger particles are discharged along the length of the cylinder.
The Wide-Use Of The Rotary Trommel Screen
The rotary trommel screen can be used for accurate particle size sorting of materials that are difficult to be screened in municipal solid waste and resource recovery, and for sorting and washing of ores, rocks, and fine-grained materials.
The Advantages Of The Rotary Trommel Screen
1 The cylinder is composed of concentric steel ends and sieve sections. According to service requirements, the screen segments are spiral design、connecting beam type.
2 Cylinder rotary suspension system supported by three or four points featuring Full concentric drum, without vibration or sway.
3 The drum is driven by chains, sprockets, gears and gears, hydraulic or friction drives.
4 The Rotary Trommel Screen is Available in a variety of diameters and lengths.
