Weigh-Veyors

Whirl-Air Weigh-Veyors are designed to provide dust-free automatic weighing and conveying of free-flowing bulk materials from storage to end use points, all in a single, compact unit. The system accurately weighs single or multiple free-flowing ingredients into a combination scale mounted transporter. The transporter then pneumatically conveys the weighed product(s) to one or more destinations.

The Weigh-Veyor design allows direct connection to the silo or hopper. The illustration above demonstrates the use of the Weigh-Veyor in a multi-ingredient application, where two ingredients are precisely metered from two sources and pneumatically conveyed to use points.

How The Weigh-Veyor System Works
Stage One Operation
Ready to begin cycle. Weigh scale is at zero. Inlet pinch valve (A) & vent valve (B) are closed. Internal space is atmospheric pressure.
Stage Two Operation
Inlet pinch valve (A) & vent valve (B) are open and outlet pinch valve is closed on signal. Air #1 is on. Material is admitted until target weight is achieved. Valves A & B close.
Stage Three Operation
Outlet pinch valve is opened, Air #2 is on and material is conveyed to receiving point until zero weight is achieved, assuring complete transfer.
