PPI Herringbone Wing Pulley - Aggregate
The PPI Herringbone Wing® was designed for those applications where conventional wings suffer from excessive material lodging and wing folding. The extreme wing angles of up to 45°, use the pulleys rotation to eject material out the sides of the pulley rather than recirculating it as a conventional wing often does. These extreme angles and optimized wing height, along with a center reinforcement disc, all combine to make an incredibly strong design that excels where others fail.
How it works:
• Herringbone wing pulley discharge material out the side of the pulley, in fewer rotations, rather than recycling material back onto the belt.
• Curved wings reduce the amount of air being moved and reduce the amount dust being stirred.
• The pulley is in constant contact with the belt; preventing belt slap, vibration, and wear. Additionally, herringbone pattern doubles the contact points in the center of the belt proving better support and further reducing vibration
• Flights angled at 45° throw material off the belt, doing a better job of cleaning and preventing material build up and plugs
