Precleaners are belt cleaners that are designed to scrape material off the conveyor belt. Precleaners are mounted to the head pulley, below the material flow. The are ideal for removing large pieces of material – typically about 60-70 percent of initial carryback. Flexco® precleaners are available in a varity of widths and blade types that can tackle even the toughest materials.
Secondary cleaners are belt cleaners that are built to scrape materials left on the belt beyond the head pulley. Secondary cleaners are located just past where the belt leaves the head pulley, and anywhere else down the beltline. Secondary cleaners are especially good at removing fines and can increase cleaning efficiency to more than 90 percent. Flexco® secondary cleaners handle a variety of applications, with polyurethane, carbide, and brush options available.
Some operators want their belts as clean as possible; others are comfortable with a certain amount of renegade material. Flexco® recommends a precleaner and one or more secondary cleaners to achieve maximum cleaning efficiency and form a comprehensive cleaning system. In some cases, a single cleaner can be mounted to target a specific area like the head pulley, for the greatest effect.
