Twin Auger Open Mouth Bag Filler

Model NWB-AF

Our Auger Fed Net Weigh Open Mouth Bagging Machine is built for applications requiring high production rates in conjunction with precise weighing.  It can also bag a broad range of finely ground industrial grade powders.  This machine was engineered to manage dosing and filling simultaneously.  Using a specially designed high-flow, twin screw auger feeder, it first doses a metered amount of material into the pre-weigh hopper.  Once there, the substrate is held until a signal releases it filling the bag instantaneously.  In addition, Model NWB-AF prevents material loss by way of a dust tight clamp that securely grip bags at the spout.  Moreover, weights are kept accurate and within tolerances by the scale’s digital display.  Lastly, a hinged drop bottom door under the auger and weigh hopper enclosure makes cleaning and maintenance fast and easy.
