Product introduction

Roller screen is widely used in coal handling system of power plant. It is used in front of coal crusher to screen out the screen material larger than the screen hole in the coal into the coal crusher for crushing, and the material smaller than the screen hole directly falls into the system by its own gravity. At present, there are many problems in the use of traditional roller screen in the market, such as blocking, winding, poor sealing, powder leakage and so on. In view of the problems existing in the traditional roller screen, members of the R & D Department of our company developed new roller screen products, which fundamentally solved the problems of blocking, winding and powder leakage.

Product advantages

1. It is easy to replace wearing parts such as screen shaft and screen plate;
2. The screen shaft is driven by single shaft of roller table motor, which does not affect the normal operation of screen machine at the same time of maintenance;
3. The screen shaft is arranged reasonably from multiple angles to effectively improve the screening efficiency and prevent coal blockage;
The wear-resistant lining plates on both sides of the box are installed, which greatly improves the service life of the equipment;
5. Coal blocking alarm and electrical control safety protection are set to avoid equipment damage caused by abnormal operation.

 Working principle of 12 axis roller screen

working principle

The screen shaft of roller screen is arranged according to different working angles, so when the material is running at a higher working angle, the speed is faster; when the material is running at a lower working angle, the speed is slower. The materials running at two different speeds start to move axially when they meet at a certain position on the screen surface, so that the materials are evenly distributed on the screen surface, so as to improve the screening efficiency and screening accuracy

Product maintenance

1. In the process of using the machine, it is necessary to check whether there are materials in the machine before starting each time.
2. Start the machine first and then feed. In case of shutdown, the material should be stopped first and then shut down. Make sure there is no material in the machine before stopping.
3. Fill the bearing with lubricating oil every three months.
4. After the machine is put into use, it shall be overhauled once every three months to check whether the chain, screen plate, bolts of the whole machine, hydraulic push rod and other parts are loose.
5. When the screen plate is seriously damaged and cannot reach the screening purpose, it should be replaced with a new one in time.
6. Maintain the hydraulic push rod device regularly. If there is a lack of hydraulic oil, it should be added in time.
