Disc Return Roller
▪ High corrosion- and abrasion- resistance
▪ Reduction of clean-up cost
▪ Reduction of extra maintenance
▪ 3x steel roller lifetime
THE IDLER ENVIRONMENT FOR JIMWAY'S DISC RETURN ROLLERS IS WET STICKY, ABRASIVE OR CORROSIVE APPLICATIONS WHERE THE MATERIAL CONVEYED STICKS TO THE BELT SURFACE.
Used where sticky materials adhere to the belt and a corrosive environment, Jimway's disc return roller has utilising durable rubber discs. In addition, materials build-up on the rollers, which causing the belt to mistrack/flap and material spillage that the rollers fails prematurely. Depending on application, three materials of support discs are available, rubber, PU and ceramic, which prevent carryback and extend the roller service life.––––––––––––––––––––––––––––––––––––––

▪ Wet/sticky material shedding
▪ Limited belt wandering
▪ 3X steel roller lifetime
▪ High corrosion-resistance
▪ High abrasion-resistance
▪ Stable in wide temperature range
▪ Eliminating any build-up on rollers
▪ Reduction of clean-up
▪ Reduction of extra maintenance
With Jimway's belt cleaners, disc return rollers can prevent material build-up and decrease the material accumulation more efficiently, especially on wet/sticky material application.
