Impact rollers Impact rollers are normally required In areas around transfer points where shock loads need to be absorbed, and to give the belt and the material carried, added protection from damage or degradation. Rulmeca Impact rollers consist of a base steel roller on which are fitted our own design of shock absorbing rubber Impact discs In various sizes held In place by welded retaining rings.

PSV rollers Return rollers The straight tracking of the belt may be compromised by the type of conveyed material, specially when this material is sticky and thereby adheres easily to the belt surface. In this case, material is also deposited on the return rollers that support the belt, adding an irregular addition of scale to the roller itself.As a consequence, not only wear and tear of the belt occurs, but forces are brought into play to move the belt away from its correct track. Return rollers with spaced rubber rings contribute largely to eliminating the build up of scale that forms in...
