Spiral Drum Pulley
Formed by a pair of vertical steel bars around a Heavy Duty Drum.
The PPI Spiral Drum pulley is formed by a pair of vertical steel bars helically wound around a Heavy Duty Drum (HDD) pulley. This unique design is frequently used when additional cleaning action is desired without introducing additional belt vibration. Rotation of the pulley automatically starts the cleaning action by discharging foreign material to the side of the conveyor.
