Different from other screening equipment, the Roller Screen relies on the synchronous rotation of multiple Screen shafts to drive the movement of materials and completes the classification of materials through the gaps between the screen plates. The rotational speed of the screen shafts is the core parameter that determines the screening efficiency, processing capacity and service life of the Roller Screen. Unreasonable setting of the rotational speed can easily lead to problems such as material accumulation, screen shaft jamming, incomplete screening, and excessive wear of the screen plates.

Roller screen is mainly applied in coal classification in industries such as coal mines and power plants. Compared with the traditional vibrating screen, the roller screen is less prone to clogging when grading wet and sticky coal, can ensure the processing capacity and screening effect, and has no vibration, low noise and good dust-proofing performance during operation. In recent years, it has been widely used in the raw coal preparation screening and fine-grained powder removal operation links of coal preparation plants, and has achieved remarkable results.

Roller screen is playing an essential role in bulk material handling , especially in coal preparation processes where abrasive or high-moisture material like lignite needs robust and reliable machinery. While utilizing a moving screen surface and self-cleaning design , roller screen performed well in handling sticky and wet materials , behind its customizable screen shaft and discs , driving system is the backbone of roller screen. Among various components, most important thing is the nylon flexible couplings , as a connection between the reducer to rotate screen shaft, to make sure the power transmitting is smooth and stable and stand with demanded operation environment.

A roller screen is a highly efficient screening device composed of main shaft assemblies formed by rotating drums that rotate in the same direction, enabling material separation and transportation. Also known as a swing feeder or disc screen, the roller screen is suitable for various materials, including wet and sticky ones.
