Spiral Drum & Wing

Spiral Drum Pulley

The Spiral Drum Pulley is formed by a pair of steel bars helically wound around the drum pulley. These bars converge at the center of the pulley and spiral out towards both ends at a 3-inch pitch. This design ensures constant contact with the belt, reducing the possibility of material build-up between the belt and pulley face.

The cleaning action of the Spiral Drum Pulley is extremely effective in high tension or high speed applica-tions, where a wing pulley cannot be used.

Spiral Drums can be made with XT®, QD®, Taper Lock®, or Keyless Locking Assemblies (KLA), available in Crown or Flat Face. Standard sizes range from 12" – 36" in diameter and 12" – 75" wide face.

Spiral Wing Pulley

The Spiral Wing Pulley is formed by a pair of flat steel bars helically wound around a wing pulley. The bars converge at the center of the pulley, spiraling out towards both ends at a 3-inch pitch, ensuring constant contact with the belt. This contact eliminates excessive noise and vibration sometimes found in standard wing pulley designs.

Rotation of the pulley automatically starts the self-cleaning action, discharging foreign material to the sides of the conveyor.

Spiral Wings can be made with XT®, QD®, Taper Lock®, or Keyless Locking Assemblies (KLA). Available in Crown or Flat Face, standard sizes range from 12" – 36" in diameter and 12" – 75" wide face.
