Valve Bag Fillers

Valve Bag Fillers

Valve bag fillers weigh, fill, and seal different types and sizes of bags and containers with flaked, powdery, and granular products using compressed air, impellers, augers, or gravity fed spouts. The filling spout is totally enclosed during the fill cycle which minimizes spill and dust emissions.

These types of machines fill valve bags weighing 20 to 110 lbs. at rates of up to 12 bags per minute. Fill rates can increase up to 24 bags per minute depending on the type of material and number of valve bag filling equipment and machines. There are many different types of valve bag fillers including manual, semi-automatic, and automatic versions. Once the bags have been filled and sealed, they are conveyed to a station where the bags are palletized, stacked, and wrapped for shipping, storage, and sale.

Valve Bag Filling Machine with Bag Densifier

First, an empty valve bag is placed on the valve bagging machine spout. During the fill cycle, the low frequency oscillating (or reciprocating) densifier is activated to settle and densify the material inside the valve bag. This allows for complete filling of the bag to reach a set point weight. Other types of densifiers are also available.
