Roller screen is a kind of screening equipment which carries out different treatments according to the particle size of materials. The roller device is obliquely installed on the frame. The motor is connected with the drum device through a reducer and a coupling to drive the drum device 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 turns and rolls, so that the qualified material is discharged through the screen of the outer circle of the drum, and the unqualified material is discharged through the end of the drum. Dust in mixed materials can be screened out, and materials of different sizes enter different funnels respectively.

Scope of application of roller screen:

1. Quarry is used to separate large and small stones, soil and stone powder.

2. The gravel yard is used for sand-gravel separation.

3. The coal industry is used to separate lump coal and coal washing (part of coal washing machinery) from pulverized coal.

4. Chemical industry and mineral processing industry are used to separate large and small blocks and powder materials.

5. Solid waste classification is used to screen out materials with dust and particle size.
