Working Principle
How Roller Screen Work
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.
The Screen surface of Roller Screen is composed of several parallel arranged screen shafts equipped with shaped screen discs, and the screen shafts are driven by the Driving device to rotate in the same direction at the same speed, forming a rolling screen surface.
When the material flows on the screen surface, it can form a material flow of equal thickness and with a certain acceleration.
The gap between the screen shaft and the screen disc forms the screen hole, the material less than the screen hole is subjected to its own gravity and the rotating force of the screen shaft, and becomes the material under the screen through the screen holes. Material larger than the screen holes continues to enter along the screen surface under the action of the rotating screen disc, becoming the material on the screen, and finally achieving the classification of the material.

Core Components
Roller Screen Core Components
Our company has skilled technical workers and perfect quality management system, to ensure the high quality of the core components of the roller screen, to provide a guarantee for the high-performance operation of the product.
Screen Shaft Assembly
The screen shaft assembly is composed of motor + reducer, screen shaft, screen disc, flat key, locking nut, coupling, bearing seat and bearing seat accessories. The drive motor is connected with the reducer and screen shaft through the coupling.
The design of the screen shaft is reasonable and safe, which can effectively avoid the phenomenon of bending and breaking of the roller shaft.
When any group of screen shafts fails, the material can continue to move forward under the push of previous screen shaft, and the screening can operate as usual. The screen shaft bearing seat is installed on the outside of the screen box side plate for easy disassembly.

Screen Disc
Roller screen is cast with wear-resistant manganese chromium alloy steel, which has good wear resistance and can cope with the impact and wear of large materials without any deformation or fracture.
Roller screen is designed as a parabolic screen disc, and is rounded to eliminate sharp corners, so that the rotating resistance of the screen is minimized.
The Parabolic shape of the screen disc can maximize the disturbance ability of the roller screen to the material flow and improve the screening rate.

Roller screen is mainly composed of screen box, driving device, screen shaft assembly, cleaning device, etc.
Screen Box
Screen Box
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 box are connected by bolts, which is easy to replace.
Driving Device
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.

Self-cleaning Device
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.
Wear-Resistant Lining Plate
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.

Protective Housing
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.

Features and Benefits
Roller Screen Features
Our roller screens are primarily for pre-screening and crusher discharge, as well as for screen or control screening after crushing.
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.
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.
Compared with traditional vibrating screens, roller screens are not prone to clogging and have higher screening accuracy and efficiency.
Easy maintenance
Roller screens are designed with modular components to facilitate quick and timely replacement of parts, reducing downtime and maintenance costs.
Environmental protection
The roller screen adopts a fully enclosed structure with no vibration, effectively avoid dust spillover, low noise, energy saving and environmental protection.
Manual/Automatic Control
The whole machine adopts electrical and mechanical dual protection,with interlock protection function,can achieve manual control and automatic control.
Self-cleaning
All the screens disc of each screen shaft are equipped with a cleaning device to prevent screen blocking, and the three sides of the screen are cast with cutting edges, so that the cleaning is more efficient and the effect is better.

Why Chooese us
Why Chooese Roller Screen
Roller screen VS conventional screens, Have the following advantages.
Roller screens distinctly outclass conventional screens, especially in the case of difficult to screen, wet, sticky bulk materials, feeding and screening is distinctly outclass to conventional screens, which often exhibit baking and sticking with these materials.
Roller Screen operate with low energy consumption and low profile requirements, and without vibration, noise or transmitted stresses, making them ideal for both stationary and portable applications.
Compared with the traditional screen that uses vibration to separate materials, the roller screen does not vibrate, the equipment is relatively strong, does not require frequent maintenance and overhaul, and the overall life of the equipment is longer.
Roller Screen are self-cleaning and designed to resist clogging and reduce blinding. They also feature an automatic lubrication system and a jog reverse function to quickly and easily solve any jamming situation.
Roller Screen can be fed by an apron feeder or directly via trucks or loaders. No other equipment is required to assist the feeding, reducing the cost of civil construction and equipment.
