IDLER SPACING. The spacing or pitch of idlers has a direct impact on the sag of the belt between the idler sets. The idlers on the carrying side of a conveyor must support both, the belt and the load carried by the belt and on the return side, the idlers must support only the empty return belt. Fig.

1. The mining industry is already aware of the potential dangers arising from 'nip hazards' on belt conveyor systems and over the last twenty years a policy has evolved of nip point guarding the main system rollers on belt conveyors. These include the drive rollers, delivery rollers, return rollers, loop rollers, and deflection rollers.

The belt does not sag between the rollers due to the impact bar, so the load does not spill or generate dust; Easy installation and replacement; The rubber hardness of 40° provides high impact absorption and minimizes damage to the belt. M = to coefficient of friction with rubber minimizes belt running resistance and keeps friction low.
