Characteristics:

The spiral drum pulley is formed by a pair of vertical steel bars wound helically around a heavy duty drum pulley "HDD". This unique design reduces the accumulation between the belt and the pulley while providing continuous belt contact for applications where wing pulleys can not be used. The rotation of the pulley automatically starts the cleaning action, discharging foreign material to the side of the conveyor. Available in crown or straight face and also with several hub and hub systems.
