Open Mouth Baggers

Open Mouth Baggers
Filling and sealing open mouth bags with Ice Melt

Fill, weigh, and seal open mouth bags with powders, pellets, flakes, granules, and fibrous materials with manual to fully-automated bagging machines.

Open mouth bagger machines have a larger spout to fill open mouth style bags, burlap sacks, pails, boxes, totes and more. These machines typically fill bags to weights of 20-110 pounds (9-50 kilograms) using mechanical or digital scales at rates up to 24 bags per minute (1,440 bags per hour).  They are used in many different types of industries including aggregate, stone, minerals, agriculture, animal feed, seed, cement, concrete, chemical, food, ingredients, landscaping products, and more.

Gross weigh bag filling machines weigh the material in the bag as it is being filled.  Net weigh filling machines pre-weigh the material in a hopper and then dump it into a bag.  Filling bags using a net weigher is about 2 times faster because the operator can easily position a bag on the spout as the hopper is being filled.

Available Models

Model GB - Mechanical Gravity

Model GB - Mechanical Gravity

This machine packages granular, free-flowing, and non-dusty products into open mouth bags. Product flows by gravity from a supply hopper into the machine. When a fill cycle is initiated, product flows through the gravity gate into a funnel spout and into the bag. This type machine is an automatic mechanical scale gross weighing filler that simultaneously fills and weighs product directly into the bag. No air or electricity is required for basic operation.

Model NWB - Net Weigh Filler Open Mouth Bagger

Model NWB - Net Weigh Filler

This machine packages granular (80 mesh or coarser), free-flowing, and non-dusty products into open mouth bags, boxes, pails, and drums. Product flows by gravity from a supply hopper into the machine. The machine automatically loads product into an internal weigh hopper without operator assistance. When a fill cycle starts, the product is discharged from the weigh hopper through a funnel spout and into the bag. At the same time as filling, the machine loads product into the internal weigh hopper for the next fill cycle. This type of machine is an automatic net weigh filler that pre-weighs material before discharging into a bag or container.

  • Fill rate: Up to 24 bags per minute

  • Accuracy: +/- 0.5-1% of target weight

900 Series - Horizontal Impeller Filler

Model GWB-GV Gravity Vibrator

This machine packages free-flowing granular and pelleted products into bags. Product flows by gravity from a supply hopper into the machine. When a fill cycle starts, the product flow is divided into two flows. One feeds to a gravity style swing gate for a faster bulk flow. The other flow goes to a vibratory pan feeder for a slower dribble type flow. As the bag approaches the target weight, the gravity gate closes, and the vibratory feeder will continue until the target weight is reached. An air-operated bag clamp secures the bag to the machine during filling and automatically releases once the target weight is reached. This type of machine is an automatic gross weigh filler that simultaneously fills and weighs product directly into the bag.

  • Fill rate: 1-10 bags per minute

  • Accuracy: +/- 0.5-1% of target weight

  • Bag weight range: 20-110 pound bags (9-50 kilograms)

Model GWB-BF - Belt Fed Gross Weigher

Model GWB-BF - Belt Fed Gross Weigher

This machine packages non-free flowing powders, granules, and flaky materials into bags. Product flows by gravity from a supply hopper into the machine. When a fill cycle starts, the product is conveyed through a specially designed belt feeder that conditions and delivers it in an even and consistent flow to the weighing scale. The product is simultaneously filled and weighed into the bag. When the target weight has been reached, the belt feeder will stop and the cutoff gate in the machine closes. The air operated bag clamps automatically release the bag from the scale. For difficult to handle materials, the gravity gate is removed completely.

  • Fill rate: 1-8 bags per minute

  • Accuracy: +/- 0.5-1% of target weight

  • Bag weight range: 20-110 pound bags (9-50 kilograms)

  • Bag types: paper, plastic, and poly-woven open mouth bags
