Tongxiang are professional conveyor equipment manufacturers in China.Coal belt conveyor is suitable for conveying all kinds of bulk materials such as granular, powder and so on. Most materials contain moisture, especially in humid environment.
If the material is attached to the surface of conveyor belt, When less than the timely clean-up, it will enter into the drive pulleys and rollers, which increase the friction and cause huge damage.

When the belt attached with material is running to the return idlers, part of the continuous contact will stick to the rollers. when the material accumulated to a certain extent, it will increase the bearing loaded both in radial and Axial, thus accelerating the roller damage and sometimes also lead to idling roller. If the attachment enters the reoriented drum, 
which may cause deviation of the conveyor. In addition, because of the cleaning is not complete with the operation of the belt machine, material attached on belt sprinkled around the conveyor, it causes some pollution to the environment. 
Well, with the artificial cleaning, it not only increase the labor intensity of workers, also reduce the efficiency of the conveyor,and prone to accidents. Therefore, equipped with a good performance 
of the cleaning device for the use of the conveyor is very necessary, not only can extend the service life of the belt machine.
