Weighing And Dosing Systems

Some conveying tasks bring up the question: How much material did the system convey and feed? The answer is CONWEIGH.

Our CONWEIGH Vacuum Conveying and Weighing/Dosing systems measure both the incoming and outgoing material flow. You can set systems to convey a certain amount or just control the feed rate over time. CONWEIGH does the rest, gives you a vacuum conveyor with booster and fine dosing function (up to 99.7% / 99.9% precision, depending on material condition).

Volkmann CONWEIGH Vacuum Conveying systems with weighing and dosing function are built on the basis of VS and PPC conveyors, thereby providing a wide range possible applications. They work gravimetrically with the vacuum conveyor mounted on a special frame completely isolated from external forces and loads. The filling weight is constantly measured throughout the suction cycle.

The amount of material to be conveyed is specified (touch screen input).  If different materials have to be picked up from a number of sending stations, the control switches the valves to activate the proper transportation line automatically. Conweigh systems are able to set up recipes.

The combined transfer/weighing Conweigh system is used for dosing weights of 2 kg and above.  Typical for vacuum conveying, the transported material is released discontinuously in cycles. The maximum dosing capacity is defined by the transportation capacity of the vacuum conveyor, for Conweigh this is up to 4 t/h. The accuracy of the system is 99-99.7% of the indicated value (configured to customer demands).

The special design and assembly provides the well known advantages of all VS and PPC Conveyors (easy accessibility and cleaning). Inquire about special systems, e.g. combinations with loss-in-weight feeders, prepared conveyors in weighing frames for on-site dosing controllers etc.
