Optimize conveyor belt cleaning systems

Controlling fugitive material in the form of dust and spillage has been recognized as a key factor in maximizing conveyor efficiency and safety. One way that operators minimize fugitive material is by using belt cleaners to remove carryback before it can escape from the system.

Most designs of conveyor belt cleaning technologies available today are blade-type units using a urethane or metal-tipped scraper mounted on the head pulley to remove material from the belt’s surface. These devices typically require a tensioner to hold the cleaning edge against the belt. Because the blade directly contacts the belt, it is subject to abrasive wear and must be regularly adjusted and periodically replaced to maintain effective cleaning performance.

Installing a blade that is wider than the material load can cause the center section of the blade to wear faster than the edges because there is more abrasive cargo in the middle. This results in an increase in carryback.
