HOW IT WORKS & BENEFITS
Our Base Model Simple Frame Bulk Bag Fillers are of particular interest to companies using bulk bags to store and/or transfer raw materials, semi-processed or finished products. This economical bulk bag filling choice should be considered when:
- Flow control is handled by a feeder, conveyor or other means of delivery.
- An operator continuously monitors the fill progress or material delivery operates on a timer or is transferring pre-weighed batches.
- No weights and measures guarantees are required.
- Only a few bulk bags are to be filled per day.
- The product deaerates well and therefore doesn’t require compaction. Alternatively, filling needs are so low that the bags can be left to hang until stable. Unstable bags containing aerated material are a safety hazard as they can fall over.
- Our Spirofil Base Model Simple Frame Bulk Bag Fillers are robust and are constructed from Steel-It polyurethane coated carbon/mild steel or stainless steel as the environment dictates. Filled bulk bags can be removed by forklift or pallet truck.
The inflatable neck seal ensures that dust doesn’t escape into the atmosphere. The filling head contains a dust filter to remove material carried away in the stream of displaced air. Filtration is unnecessary for dust-free granular materials such as certain plastics.
Spiroflow only offers their Spirofil Simple Frame Bulk Bag Fillers for applications where we are confident of their suitability.
YOUR REQUIREMENTS
Before selecting a particular bulk bag filler, some key factors need to be considered. This not only helps to assess a customer’s own particular needs but also assists our design engineers in determining the optimum system for those needs.
A. By pallet or by the bag loops.
A. At this stage, you should consult both the bag manufacturer and Spiroflow to determine the proper bag style and size. The bag needs to optimize its volume for safe storage and transport. Spiroflow has seen outstanding results with Ameriglobe’s Fusion Baffle Bag, which is manufactured without sewing and, in most cases, does not require a liner.
A. An inflatable neck seal effectively contains the dust during filling. All our filling heads have an inner product flow and an outer annulus for dust evacuation. A dust extraction port is also included.
A. If filling by volume, options such as pallet dispensers, automatic bag loop release, bag take-off and accumulation conveyors should be considered. These can be added at a future date to standard Spiroflow bulk bag filling equipment.
A. If the area poses an explosion risk, static dissipative or groundable bags may be recommended together with a suitable static monitoring device.
A: Nitrogen purging is an option. Traditionally when bag filling, the bag would be inflated with air before filling commences, but nitrogen can be used instead to increase product shelf life.
A. If the product is very fine, you probably will, to prevent leakage or moisture ingress. However, various alternatives can be used such as coated bags or special bag seams. The liner must be inflated correctly to avoid creasing and subsequent discharge problems.
A. Usually, yes. Vibration at the base of the unit deaerates and compacts the product to optimize the bag volume and form a safe and stable load. The CTE bulk bag filler uses our patented Cone Table densification for highly aerated powders.
A. Automatic loop release is available but height adjustment is not offered on the CS Base Filler the C-Series & CTE bulk bag fillers offer height adjustment. Yes, automatic loop release of filled bags is a useful labor-saving option for pallet loaded bags. Powered height adjustment is also recommended if different sized bulk bags are being filled in order to speed up the filling process.
A. Yes. Spiroflow supplies a range of options for filling rigid bins, drums, and boxes/octabins.

Dust Control/ Air Displacement
Fill nozzle with dust extraction vent
The filling nozzle design includes an inner open-ended cylinder, with a second concentric cylinder (one end closed by an annulus) attached to it.
The product passes through the center cylinder into the bulk bag while displaced air & dust is routed through the outer chamber & through a dust sock to a dust collection (by customer) connection.
Bags are secured to the nozzle with an outer spring clamp.
Product Contact Surfaces: Stainless Steel Only
COMPONENTS & OPTIONS
CONTROLS
Our Base Model Simple Frame Bulk Bag Fillers are not offered with controls. There are switches to control simple operations during the filling process.
