What is the bend pulley and snub pulley? - SKE

2021-5-14  The bend pulley and snub pulley are the same. We classify it according to its function in conveyor belt. When we use it to change the direction of the belt, we can call it bend pulley. When we use it to increase the wrap angle, we can call it snub pulley. On the drawing above, we can even see a group of drums whose goal is to tension the belt.

Snub Pulleys in Belt Conveyors - bulk-online

2007-11-10  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 another angle; sometimes these pulleys are called ...
