Belt Cleaners & Accessories
About belt cleaners
Belt cleaners are an integral part of your belt conveyor system because of their ability to remove carryback from your belt. Carryback is a leading issue on many conveyors, requiring frequent clean-up while wearing our conveyor components prematurely and causing other conveying problems like belt mistracking. Reducing carryback can improve worker safety, increase operating efficiency, and enhance productivity.
Basic information
Belt cleaners are primarily divided into two parts precleaner or primary belt cleaner and secondary belt cleaner.
- 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.
- They are ideal for removing large pieces of material – typically about 60-70 percent of initial carryback.
- 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 leave the head pulley, and anywhere else down the beltline.
- It increases cleaning efficiency to more than 90 percent.
Design attributes and advantages
Flexco has a unique, patented, faceted blade profile. These blades continually renew their edges creating more efficient cleaning. Heavy-duty spring tensioning systems is an important part of the cleaning system. These tensioners enable easy visual inspection and maintain proper tension. Larger diameter poles are designed to resist powerful twisting forces caused by continuous belt motion.
