Open Mouth Bagging Machine
Use an open mouth bagging machine to weigh and fill open top style bags with granules, pellets, powders, flakes, and fibrous materials.
An open mouth bagging machine has a larger spout to fill open top style bags, sacks, 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). They are used in different types of industries including animal feed, seed, pet food, fertilizer, salt, landscaping products, chemicals, food ingredients, nuts, and more.
What is the difference between a gross weigh bagging machine and a net weigh bagging machine?
A gross weigh bagging machine weighs the material in the bag as it is being filled. A net weigh bagging machine pre-weighs the material in an internal weigh hopper and then dumps it into the bag. Filling bags using a net weigh bagging machine is about 2 times faster because the operator can position and fill a bag clamped to the spout as the internal weigh hopper is being filled above.

Model 350
DigitalPLUS Open Mouth Bagging Machine
This is a very popular digital bagging machine used to fill up to 10 bags per minute, or about 500 bags per hour. It includes a more advanced scale controller with foot pedal or wand switch activation.
The base Model 350 is designed for packaging granular and free-flowing products into open mouth bags (50 lb grain bags being the most popular). An empty bag is placed on the fill spout, and the operator depresses the foot pedal to clamp the bag to the spout. Product automatically starts flowing by gravity into the bagging scale and then into the bag. Once the bag has reached a set target weight, the internal flow control gate closes, and the bag clamp releases the bag from the fill spout automatically dropping it onto a bag closing conveyor below.
This type of open mouth bagging machine uses an automatic digital gross weigh scale to simultaneously fill and weigh the product directly in the bag. Add a belt feeder, twin auger feeder, or vibratory feeder for more difficult flowing / sticky products or powders.
Fill rate: 6-10 bags per minute
Accuracy: 0.1 lb (0.05 kg) weight accuracy
Bag weight range: 10-110 pound bags (5-50 kilograms)
Bag types: paper, plastic, and poly-woven open mouth bags

Models 600 - 1500
Digital High-Speed Net Weigh Bagging Machine
This type of open mouth bagging machine fills the fastest with speeds up to 24 bags per minute or more. It is considered the open mouth bagging machine of choice for high volume or industrial bagging operations that bag animal feed, minerals, salt, aggregate, corn, nuts, and more.
The base Model 600 is designed for packaging granular and free-flowing products into open mouth bags (50 lb grain bags being the most popular). An empty bag is placed on the fill spout, and the operator depresses the foot pedal to clamp the bag to the spout. The fill cycle starts, and the product is discharged from the internal weigh hopper, through a funnel spout, and into the bag. At the same time as material is discharged, the machine loads product into the internal weigh hopper for the next fill cycle. This type of machine is an automatic net weigh bagging machine that pre-weighs material before discharging into a bag or container. Add a belt feeder or a twin auger feeder for more difficult flowing products or powders. Add a vibrating pan feeder for more precise dosing.
Fill rates (accuracies of ± 2 ounces for most products):
- Model 600 (single scale / simplex) 14 bags per minute

Belt Fed
Open Mouth Bagging Machine
Add a belt feeder to any of the machines above for bagging non-free flowing products like sticky animal feeds, wood chips, screened soils, and some flours like cake mix.
Belt feeders are designed for semi-free flowing products over 1 inch in size, materials containing 7% molasses or more, oils, certain powders, or any product that is not dry, granular, and free flowing. Each unit includes an adjustable stream depth regulator and a belt scraper to ensure consistent, clean operation.
Product flows by gravity from a supply hopper into the inlet of the belt feeder. 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 machine. When the target weight has been reached, the belt feeder stops and the cutoff gate in the machine closes. Then, the bag is released 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

Materials of construction options: mild 10-gauge steel (standard), stainless steel product contact surfaces, all stainless steel, all stainless steel for food grade applications
Additional upgrades: Endless food grade belt, heavy duty aggregate belt, white oil resistant belt (for pet foods, animal feeds, and various products that contain oils)
Compressed air: 80 PSI required at 1 CFM per bag fill cycle
Electrical: 220 volt, 380 volt, 440 volt or 575 volt / 3 phase / 60 cycle

Auger Fed
Open Mouth Bagging Machine
Add an auger feeder to any of the machines above for bagging flour, fine powders, or other finely ground products that will flood past a gravity gate or belt feeder.
Product flows by gravity from a supply hopper into the inlet of the auger feeder. When a fill cycle starts, the product is conveyed through a specially designed auger feeder that conditions and delivers it in an even and consistent flow to the bagging machine. When the target weight has been reached, the auger feeder will stop and the cutoff gate in the machine closes. Then, the bag is released from the scale.
Fill rate: 1-5 bags per minute (at 50 lbs each)
- Note: Production speeds are decreased 25-35% with auger feeders to prevent further aeration of the product.
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
- Powders

Vibratory Fed
Open Mouth Bagging Machine
Add a vibratory pan feeder to any of the high-speed net weigh bagging machines above to fill bags with free-flowing granular products and pellets into bags with a high degree of accuracy. Vibratory feeders can also be heavy duty for products like aggregate.
Vibratory pan feeders are a must when target fill weight accuracy is critical.
During each filling cycle, product flows by gravity from the supply hopper into a pantleg diverter, which directs material to both a gravity gate and a vibratory pan feeder. The gravity gate delivers fast, bulk flow, while the vibratory feeder provides slower, dribble flow. As the target weight is approached, the gravity gate closes, and the vibratory feeder finishes the fill with precise dribble feeding until the exact weight is reached. Then, the bag is automatically released from the scale.
Fill rate: 1-10 bags per minute (at 50 lbs each)
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
- Grains
- Seeds
- Flour
- Rice
- Soybeans
- Animal Feed
- Bird Seed
- Wood Pellets
- Activated Carbon
- Pea Gravel
- Sugar
- Salt
- Cake Mixes
- Spices
- Milk Powder
- Fertilizer
- Ice Melting Salt
