Carryback on the conveyor belt - in the form of very fine particles, it can be wet, sticky and sometime in the form of slime, that adheres to carryside of belt and they fall off along the return side of conveyor.
It can be easily seen as pile of material build-up around snub pulley, under bend pulleys and along return idlers.
Carryback builds-Up on Components, burying idlers, seizing bearings, and causing belt wander.
Measuring carryback is important as part of belt cleaning maintenance. By measuring carryback one can improve the maintenance program and selecting the right belt cleaner or to add more belt cleaners.
Supra offer carryback measure using the concept of Stahura Carryback Gauge. Stahura carryback Gauge is first introduce by Mr. Dick Stahura of Martin Engineering, who has spent over 50 years working to improve bulk material handling. He pioneered the engineered approach to solving the problems of dust and spillage around conveyors.
Dick has carried his message around the world, to mines, power plants, and anywhere “DURT"--his unique term for the fugitive material released from belt conveyors--presented the opportunity to improve efficiency and productivity. Dick became so well identified with these concepts that for a number of years Martin Engineering has used his caricature as a trademark for its conveyor products. This character’s name - “TC” - is short for the catchphrase Dick has long advocated as the first step in improving conveyor performance: “THINK CLEAN®!”
