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.

To give you a good idea about the types of valve bag filling equipment available, we have included different examples with descriptions, images, and videos. Learn more about filling plastic and paper bags with food products such as seed, grain, salt, flour, sugar, cocoa, cake mixes, and more. You can also fill valve bags with chemical and industrial products like carbon black, TIO2, Iron Oxide, Zinc Oxide, Hydrated Lime, plastic pellets, fertilizer, plaster, sand, grout, stucco, concrete, cement, gypsum, bentonite, barite, garnet, and graphite.
These valve bag filling machines are used to fill 50 Lb. paper valve bags with different types of high-quality silica sand. After filling, bags are conveyed to an automatic palletizer that stacks the bags on a pallet.
This type of silica sand is a high-quality round and sub-round silica sand with mesh sizes ranging between 8×16 and 100. It has many uses including:
turf sand used for infill to protect artificial turf and increase its life expectancy
roofing sand for specialty roofing tiles, flooring titles, and colored grout
building and industrial sands as an ideal base for construction, concrete, bricks, foundry, and flooring
water filtration sand used in wells, filters, and other water fixtures
The bagging system shown in the video below allows one operator to use 3 valve bag filling machines, or air pressure packers, to fill 50 lb. bags of fertilizer at a rate of 15-18 bags per minute.

This semi-automatic system fills batch inclusion bags with blended pigment powders used for road markings. After filling, the bags are conveyed to a palletizing station.
Process Description
Blended pigment powder used for road marking is conveyed to a bucket elevator that discharges it into a 25 cubic foot hopper. Then, the powder flows by gravity into the air chamber of the valve bag air packer.
End-of-line robot picking up 100 lb. bag of minerals using a bag gripper tool
A contract packaging company recently added an end-of-line robot to their existing valve bag filling system. The new robotic palletizing system includes bag handling and robotic pick conveyors, a used Fanuc robotic arm that has been reconditioned with a bag gripper tool, and an automated pallet and slip sheet dispenser.
With the added palletizing automation, the entire system is now able to fill and stack 100 lb. paper valve bags at a rate of 10-12 bags/minute. The company can also quickly swap out settings to fill and stack 50 lb. valve bags at a rate of 15-16 bags/minute.
This grain bagging system uses a type of bagger called an air packer to fill 50 pound bags with shelled corn, also known as shell corn, kernel corn, feed corn, or deer corn.

This is a 3 spout, side-by-side system for filling hydrated lime powder into 50 pound paper valve bags. The valve bag fillers are all impeller packers.
Filling Hydrated Lime Powder into 50 pound Paper Valve Bags
There are many different types of bagging machines using custom configurations to package many types of products. These products can range from agricultural products like corn, feed, and seed to chemical and industrial powders like graphite, gypsum, and barite.
Automatically place, fill, and seal bags of flour products or baking mixes in a sanitary filling operation.

Using an automated bagging system is a great way to reduce the operational costs of your bagging operation. Not only does it allow operators to accomplish other tasks, it also reduces the chance of repetitive motion injuries.
Gravity Flow Open Mouth Bagger used to fill fertilizer bags
A fertilizer bagging machine, such as the Gravity Flow Open Mouth Bagger, fills open mouth bags with dry, free-flowing and minimally dusty fertilizer granules at a rate up to 5-8 bags per minute (300-480 bags per hour). The bags most commonly used with this machine are an open top poly bag or a poly-lined paper bags. The bags are filled to a 50-pound target weight.
This valve bagging machine (CBE Model 250 Re-Bagger) allows for recycling and repackaging of rejected material from existing open mouth and valve bags into valve bags. It is capable of filling up to 5 bags per minute.
The volumetric auger bag filler with a high intensity densifier is used for filling bags with light weight fibrous materials such as linted cottonseed hulls, cedar fiber and synthetic fibers.
This flour bagging machine fills and seals valve bags at a rate of 3-4 bags per minute with good weight fill accuracy. Filling can be mostly dust free with this type of flour, but dust collection is still recommended. This is a proven design refined over many years to give users an accurate fill weight. It is ergonomically designed to reduce repetitive motions and have a quick fill time with convenient access for maintenance.
The CBE Model 730 Pressure Flow Air Valve Bagging Machine is used for bagging mineral powders, mortar mixes, or food products into valve bags with internal spouts. Types of powders can include cement powder, specialty chemical powders, bentonite, barite, sodium bicarbonate, limestone powder, and mortar mixes. This bagging machine can also be used for food products like flour and cake mixes.

The operator, or automated bag placer, spouts the valve bag onto the machine. Then, compressed air forces the powder material from a hopper above the bagging machine into the bag. When the valve bag is filled to a set weight, it drops away onto a take away conveyor.
