Open Mouth Baggers and Bagging Scales

Open Mouth Baggers
Filling open mouth bags with crushed aggregate

Fill, weigh, and seal open mouth bags with powders, pellets, flakes, granules, and fibrous materials with manual to automatic baggers and bagging scales.

grain feed and seed bagger - 50 lb bagging machine

Open mouth baggers 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 bagging scales at rates up to 24 bags per minute (1,440 bags per hour). Smaller baggers typically fill bags and pouches to weights of 1-25 pounds using digital net weigh scales at rates up to 30+ bags per minute or (1,800 bags per hour). They are used in many different types of industries including aggregate, stone, minerals, agriculture, animal feed, pet food, seed, cement, concrete, chemical, fertilizer, food, ingredients, nuts, landscaping products, and more.

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

High-Speed Net Weigh Bagging Machines

These types of open mouth baggers package 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 bagging 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 internal weigh hopper, through a funnel spout, and into the bag. At the same time as material discharge, 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. It is considered the open mouth bagger of choice for high volume or industrial bagging operations that bag animal feed, aggregate, corn, nuts, and more.

  • Fill rate: Up to 24 bags per minute

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

Belt Fed Bagging Machines

This type of open mouth bagger packages non-free flowing powders, granules, and flaky materials into open mouth bags (eg. sticky animal feeds with molasses). 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 bagging 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 clamp automatically releases 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)

Vibratory Fed Bag Filling Machine

This type of bag filling machine packages free-flowing granular products and pellets 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 feeding material 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

Auger Fed Bag Filling Machines

This type of bag filling machine packages free-flowing, non-free flowing and floodable powders into open mouth bags. Product flows by gravity from a supply hopper into the machine.

This type of machine is an automatic digital scale gross weighing filler that simultaneously fills and weighs product directly into the bag.

  • Fill rate: 1-5 bags per minute
