Roller Screen

Roller screen, also known as Wobble Feeder, Disc Screen, It is mainly composed of a box, a box liner, a gear motor, a roller assembly, a bearing, a bearing seat, and a cleaning device.

In roller screen, the separation surface is formed by a gear disc, which is mounted on a rotating drum in a staggered configuration and is used to transport, circulate and loosen the material. The separated fine material falls through the gap between the individual rollers, while the coarse material is transported through the roller screen with the help of the gear disc to the overflow port.

In addition, because the roller screen adopts step conveying material, the downstream crusher can feed smoothly; Reduce the working load of the crusher. This can obviously reduce wear and tear and reduce energy consumption, thereby reducing operating costs and improving operational safety.

The compact design derives from horizontal and stepped material flows, as well as a wide range of possible layout options, enabling it to be used in a variety of complex operating environments. roller screen is widely used in power, coal, chemical, mining, waste treatment and other industries.

working principle

The screen surface of the roller screen is composed of a number of parallel arranged screen shafts equipped with screen sheets, which are driven by a transmission device to rotate the screen shaft, and the rotation direction is the same as the material flow direction. The gap between the screen shaft and the screen sheets forms the screen hole, the material less than the screen hole is subject to the action of its own weight and the rotating force of the screen shaft, and becomes the material under the screen through the screen hole, and the material larger than the screen hole continues to move forward along the screen surface to become the material on the screen, and finally realizes the classification of the material. Electrical and mechanical overload protection is provided to prevent material from jamming the screen shaft. The screening particle size needs to be adjusted according to the user's requirements, the clearance of the screen shaft and the size of the screen sheet.

roller screen structure

FEATURES

►The coil is made of alloy wear-resistant material, durable, easy to replace and repair.

►Wide adaptability to minerals and working conditions, not easy to clog, especially for high moisture minerals.

►Because the single machine uses single axis rotation, the roller motor with large starting torque is used, the whole roller transmission is stable and reliable, low noise, energy saving and environmental protection.

►With high throughput, it can handle wet and cohesive materials, and can be operated by a single gear motor or a chain driven by a motor with multiple screen shafts.

► The screen shaft rotates at uniform speed, and the whole machine has no vibration and high reliability.

APPLICATION
Roller screen is widely used in the screening of solid materials in coal, electric power, metallurgy, cement, sand aggregate, solid waste and other industries.
