mm | 356 | 483 | Roller Screen Distributor The screen surface of a roller screen is composed of many parallel arranged rollers with staggered screen plates, and the gap between adjacent rollers and disks is the sieve hole of this type of screen. The roller rotates through sprocket or gear transmission, and its rotation direction is the same as the direction of material flow. Roller screen is often used for screening coarse materials and is suitable for screening soft and medium hard materials. Its advantage is that it does not block the screen.
