Get PriceSnub Pulleys in Belt Conveyors. Nov 10, 2007· Snub pulleys are mostly installed in belt conveyors in order to achieve a higher angle of wrap on the drive pulley; in this cases the wrap angle on the snub pulley is in the area of 15° to 30° At other locations in the belt conveyor pulleys with smaller diameters (similar to the diameter of snub pulleys) are installed to lead the belt into ...
Get PriceSnub pulleys are used to increase the wrap angle of the conveyor belt to reduce the pulling force of the belt. Snub pulleys can therefore optimise the cost of your conveying system, since they reduce the belt tension which means that a conveyor belt with a lower belt strength can be used for the same purpose.
