Buffer idler

lmpact rollers are used and positioned corresponding to the load points, where the lumps and the weight ofmaterial falling onto the belt could damage. To limit the impact effect of the material onto the rollers, the latter arecovered with a series of rubber rings of adequate thickness and resistance. lmpact rollers are under stress not onlyfrom the load of the material, but also from the dymamic forces as the load falls onto the belt. The impact onto thebelt, arising from the free fall of material wil be naturally greater than in the case where the material is deflected ontothe belt by an inclined plate For the correct dimensioning and the choice of impact rollers in relation to the load checkthe characteristics of the base roller.
