Scraper conveyors usually carry sticky materials such as coal dust, mud, and powdery materials, some of which will stick to the working surface of the conveyor belt and cannot be removed when unloading. At this point, the adhesive material will enter the lower idler pulley of the empty section, soil the rollers and stick to these accessories. The material enters the roller housing, thereby increasing the radial load and axial load on the bearing seat of the scraper conveyor, causing the bearings to wear quickly. The roller housing material tears and pulls the surface of the conveyor belt, accelerating the wear of the conveyor belt.
If the adhesive enters the tail of the scraper conveyor and turns to the drum, it will stick to the surface of the drum. The greater the viscosity, the stronger the adhesion. The result is a loss of conveyor belts and increased belt wear, with serious consequences. The material remaining on the conveyor belt also increases the friction on the rollers, which sometimes causes the surface rubber of the belt and the roller cover to tear. If the cleaning device is good, the service life of rollers, conveyors, etc. can be extended. It can be seen that the cleaner has a non-negligible effect on the scraper conveyor. In operation, if you want to manually remove the attachment of the tail roller, it is often easy to cause serious personal injury or death.
Therefore, in order to ensure the normal operation of the scraper conveyor, the accessories on the conveyor belt must be cleaned between entering the face lifting wheels.
