When you’re dealing with mechanical conveyors, it’s crucial to minimize the effect of carryback. Not only can carryback ruin your belts, but it can cause product and food safety violations. Follow these tips for managing carryback in mechanical conveyors.
Switch from Chain to Belt Conveyors
While there are certain advantages to chain conveyors, many people prefer belt conveyors because they are much easier to clean. Chain conveyors have many cracks and crevices where dirt, grease, and other particles can stick, increasing the chances of carryback on your conveyor system.
Use Non-Stick Belts
Since material carryback is one of the top causes of conveyor belt failure, it makes sense to use a belt that prevents sticking. Grease, oil, and other sticky substances clinging to the belt can trap other particles, creating buildup. Non-stick belts like Teflon won’t allow anything to stick, preventing carryback.
Invest in a Belt Scraper
A belt scraper is a device that does what it sounds—it scrapes carryback material off your belts to ensure there is no buildup between production cycles. Many belt scrapers are specially designed to work with your conveyor system for an efficient cleaning process.
Using the Right Cleaners
When was the last time you or any of your staff inspected the cleaning fluids and dilution ratio used to clean your belts? If you can’t remember, then it’s time to take another look at things. Double-check with your belt provider to see what kind of cleaners you should be using, given the type of conveyor system you have. Make sure your staff know the updated cleaning procedure.
Protective Coatings
Another way to prevent carryback in mechanical conveyors is to use belts with protective coatings. Some coatings resist abrasion and heat, while others help prevent carryback altogether. Talk to a belting supplier to see what kinds of belts are right for your plant or warehouse.
Eliminating Carryback
In many types of production lines, carryback can cause serious problems. It can cause contamination, and buildups can cost you precious time and money with repairs. Follow the tips above to start eliminating carryback in your mechanical conveyors.
