Description:
Roller screen is an efficient screening equipment, the screening area consists of many parallel arranged roller shafts, the screen shaft is equipped with a number of staggered screen discs, the roller shafts rotate in the same direction, to realize the feeding and screen of materials.
Roller screens, also known as wobble feeders and disc screens, are very suitable for bulk materials that are difficult to screen, including wet and sticky materials.
Compared to traditional vibrating screens, roller screens are less prone to clogging and can guarantee both throughput and screening results. With its outstanding advantages, our roller screen is widely used in coal, mining, metallurgy, chemical industry, sand aggregate and other industries.

Product Details:
Screen Disc
Roller screen disc with staggered layout, more reasonable design. Roller screen disc has good impact resistance and will not appear any deformation and fracture phenomenon.
Roller screen disc has good wear resistance and long service life. The parabolic shape screen disc has reasonable design and high assembly accuracy, which can improve the screening accuracy.
Driving Device
It adopts single-axis single-motor drive or multi-axis chain combination transmission mode, reasonable power configuration and screen surface structure to evenly distribute the material load in the screen and ensure smooth operation.
The design structure of the driving device is simple, easy to install and disassemble, and the connected screen shaft is not moved when disassembling.
The driving device is compact in size, light in weight, long in life and low in maintenance cost.
Screen Body
The main body of the roller screen is welded with low-alloy high-strength structural steel. All screen shaft assemblies are fixed to the machine body through connecting bolts. Wear-resistant lining plates are installed on the side of the machine body to avoid direct contact between materials and the box, greatly extending the service life of the equipment. And the wear-resistant lining plate and the Screen Body are connected by bolts, which is easy to replace.
Protective Housing
The protective housing of the roller screen is welded with NM500 wear-resistant alloy steel plate, sprayed with anti-rust and anti-corrosion paint, and connected with the hopper and the outlet housing at the front and back.
The protective housing plays a sealing role, and the closed screen box can prevent materials from falling, prevent rain and snow weather from affecting the operation of the equipment, and protect the safety of personnel.
The overall sealing of the screen box can effectively prevent dust pollution, reduce the impact on the environment, and meet the requirements of green construction.
The protective housing is provided with an observation window to facilitate the observation of the operation of the machine.
The protective housing is detachable, which is very easy to repair and disassemble.
Wear-Resistant Lining Plate
The wear-resistant lining plate is made of alloy material, and the whole production process adopts welding, heat treatment, machining and other assembly line production, which has a long service life and strong wear resistance, toughness and impact resistance.
The inside of the screen box and the contact surface between the guide groove and the material are provided with wear-resistant lining plates, which can protect the screen box and increase the life of the guide groove. The lining plate is fixed together with the mother plate by bolts, and the replacement is convenient.
Self-cleaning Device
The self-cleaning device of the screen shaft is made of wear-resistant steel and is equipped with a cutting edge, which is inclined to the lower part of the screen shaft. Some fibrous debris and sticky materials attached to the screen will be automatically cleaned off by the cleaning device to solve the blockage of the screen surface.

Feature:
• Pre-Screening
The roller screen is used to pre-screen the material before the primary crusher,reducing the amount of material entering the primary crusher. This not only reduces unnecessary wear on the primary crusher,but also reduces the required size and capacity of the crusher needed.
• High Screening Accuracy
The roller screen is very suitable for bulk materials that are difficult to screen,especially for wet,coarse,sticky and other materials with good screening effects. Compared with traditional vibrating screens,roller screens are not prone to clogging and have higher screening accuracy and efficiency.
