Damp, sticky materials or humid conditions can cause conveyor issues thanks to a build of material on the belt or the rollers. Steel rollers are prone to material build up and corrosion caused by moisture in the environment. Corroded rollers seize and stop turning causing the belt to wear into the roller face resulting in sharp edges and can cause damage to the belt and downtime of a machine. King Roller, is a polymer alternative to steel which is up to 14% more power efficient, the triple labyrinth seal prevents moisture and materials getting into the bearings to prevent bearings seizing. The Polymer material used in King Roller will not corrode. We also recommend installing a Cover Clean belt cleaner to your conveyor – this does as it says on the tin – removes material from your conveyor to protect the rollers.
