GZM is a single-mouth or double-mouth spiral valve bag feeding and weighing machine with a built-in material feeder, dedicated to filling dry powder or small particles into the valve bag, such as cement, Binder powder, lime powder, fine sand, PVC particles, polypropylene particles, etc. The machine has two variable speed drives for fast and slow filling on the main screw feeder, and a third slow feeder connected with the vibrating feeder pipeline to ensure the accuracy of the bag weighing.

The GZM packaging machine weighs the packaging bags and materials when filling materials. The double-station spiral filling system can package material fastly (3-4 bags per minute, generally 20kg per bag), while ensuring high measurement accuracy!
