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,
but also improve the operation efficiency and stability of the conveyor. At present, there are a wide range of sweepers. But the shortcomings of the existence is obvious: the cleaning of the
material accumulated in the cleaning plate and the elastic body, so that the cleaning block from the tape surface gap is too large, affecting the elastic body of the pressing force, resulting in cleaning effect is not ideal.
Use a little longer, the elastic properties of the decline, aging, open plastic, shedding and so on. In addition, with the use of the sweepers in the wear, the contact point with the conveyor will slowly move down to its limit position,
the cleaning block is easy to roll to the other side of the conveyor, loss of cleaning capacity, Will tear tape. And because the cleaner frequency is high, many times the downtime will reduce the efficiency of the conveyor.

(1)most of the sweepers are only installed in the conveyor head and tail two, and the actual production, the belt machine sometimes reached hundreds of meters or even a few hundred meters,
so the cleaning effect is not very good, according to the actual situation Appropriate in the key parts of the installation of cleaning device.
This intermittent cleaning has greatly improved the cleaning capacity of the sweepers.
(2)In order to facilitate the adjustment of the position of the cleaner installation, but also to ensure that the cleaning block in the wear to maintain a certain range of adjustment, the appropriate increase in the belt machine head
sweepers at both ends of the slide.
3) Increasing the number of cleaning rollers in the conveyor, such as the rubber disc return roller, it cleaning the belt well and reduce the damage to the belt. And with the cleaning return rollers will not effect the working of the conveyor.
