'''Belt Scrapers''' are exceptionally simple in design, its operations can certainly save thousands of man-hours, reduce injury hazard and prevent downtime from damaged components. These are used in bulk material handling belt conveyors to avoid material carry back and reduce spillage. Clean belts help prevent material build-up on snub pulley & return idlers, thereby reducing maintenance and downtime. The function of an efficient belt cleaning system is to remove the fugitive material which remains on the return strand of the belt and to assist in spillage control by returning that material to the main material flow within the confines of the discharge chute. | |||
==Types of Belt Scrapers== | |||
*Primary belt cleaners or Precleaners | |||
Primary belt cleaners or Pre-Cleaners are an essential part of any conveyor system. Belt cleaners help remove bulk material product carry back and prevent it from falling off at various points of the conveyor along the return side of the belt causing various housekeeping and conveyor belt maintenance problems. These are installed at a positive angle, these primary belt cleaners would be mounted directly against the head pulley below the normal trajectory path of the material. | |||
*Secondary Belt Cleaners | |||
Secondary Belt Cleaners remove bulk material product build-up and prevent it from falling off at different points of the conveyor. Points along the return side of the belt can cause various conveyor belt maintenance problems due to carry-back. | |||
Installed after the point where the belt leaves the head (discharge) pulley and or anywhere on the return side of the belt where it can be cleaned and maintained effectively. | |||
