The Model GWB-GV vibratory pan fed gross weigh bagger accurately fills open mouth bags with free flowing granules. Product flows using gravity, from the supply hopper bin into the product feed inlet at the top of the machine. The product is divided into two flows: one feeds to a gravity style swing gate (fast/bulk flow). The second feeds into a vibrating pan feeder (slow/dribble flow). The two feeders work together to deliver products to bags. When target weight is reached, the gravity gate closes and vibrating feeder stops. An air operated bag clam secures the bag to the spout, and automatically releases it once the target weight is reached.

Clean Operation:

The operator will place an empty bag into the spout and press a foot pedal to start the fill cycle. The foot pedal causes the air operated bag clamp jaws to close and hold the bag. The scale automatically sets itself to “auto-zero” and product is weighed, fed and loaded into bags. The combination gravity and vibration of pan feeders delivers product from the supply bin above into the empty bag below. When target weight is reached, feeders will stop, and air operated clamps will automatically release and discharge the bag from the filler.
