Bulk Bag Filling: Integrated Conveying Solutions

January 5, 2022

Many companies are shipping their product to customers in bulk bags (also known as Flexible Intermediate Bulk Containers, or FIBC’s). Depending on the process, a facility may fill its bulk bags directly off the production line or, alternatively, from finished goods inventories. In either case, a conveyor often needs to be integrated with the bulk bag filler to transfer material for filling the bags. In this blog we look at the integrated conveying solutions for bulk bag filling available from UniTrak.


Most bulk bag fillers available in the marketplace today are designed to receive product directly from a production process. Since many facilities are using bulk bags of various sizes, most bulk bag fillers available today have an adjustable frame that easily adapts to a variety of bag sizes.

Many bulk bag fillers work by allowing the empty bag to be mounted onto the frame of the filler and secured by a ventilated collar. Once the bag is in position, an operator can release material into the bag. As the released material fills the bag, displaced air is vented through the ventilated collar. Many manufacturers have designs that permit direct connection a facility’s dust collection system to trap any dust generated during the filling operation.


These mini cases are examples of how various conveyor types can be successfully married to a bulk bag filler.

#1: Aeromechanical conveyor integrated with a bulk bag filler. Aeromechanical conveyors, such as the Powderflight line from UniTrak, are a great equipment choice for moving fine powders to a bulk bag filler, especially those types of powders that are difficult to handle. These conveyors can move significant amounts of powders quickly and easily, either from the production line or finished goods stores.

#2: Continuous bucket elevator integrated with a bulk bag filler. Continuous bucket elevators, such as the TipTrak™ line from UniTrak, can move a wide range of bulk solids at rates up to 2552 cu. ft. per hour. These conveyors are a proven way to transport pellets, granules, flakes, and solid shapes on to a bulk bag filler.

#3: Flexible screw conveyor integrated with a bulk bag filler. Great for batching operations, flexible screw conveyors like the UniFlex line from UniTrak offer a cost-effective way to move batches of product on to a bulk bag filler. These easy-to-use conveyors can move a wide range of free and non-free-flowing bulk materials, from coarse to fine powders, with no separation of blended products.


Bagstander bulk bag fillers are designed with an adjustable framework that will straddle a pallet or optional platform scale with controller-enabled bulk bag weight control. Bagstander fillers are constructed with a fully welded frame made from carbon steel, with stainless steel construction available as an option. The ventilated collar is manufactured from stainless steel and fitted with removable dust sock which allows for direct connection to a dust control system. A fork-lift (FLT) option is also available which enables the filler to be easily moved to different locations. This option adds integrated fork-lift pockets, together with a solid bottom plate and cross braces for additional strength.

Bagstander bulk bag fillers are designed to fill bulk bags with accuracy and safety.  Utilizing a low-maintenance design, Bagstander bulk bag fillers offer years of trouble-free operation.
