A Guide to Choosing a Bulk Bag Filler
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.
Q. How do we handle the bulk bag?
A. By pallet or by the bag loops.
Q. What bag style and size do we use?
A. At this stage, you should consult both the bag manufacturer and Spiroflow. The bag needs to optimize all its volume for safe storage and transport
Q. How do we contain dust?
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.
Q. Will the equipment need to be grounded?
A. If the area poses an explosion risk, static dissipative or groundable bags may be recommended together with a suitable static monitoring device.
Q. Do we need a bag liner?
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.
Q. Is your product highly aerated? Do you have problems producing upright, stable bags?
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.
Q. Is automatic loop release and height adjustment available?
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.
Q. Can the equipment be adapted to fill other containers?
A. Yes. Spiroflow supplies a range of options for filling rigid bins, drums, and boxes/octabins.
With an almost unlimited combination of filler designs, features and upstream equipment from which to choose, specifiers have the ability to tailor bulk bag filling systems according to capacity requirements, expandability, safety concerns, plant hygiene considerations, ancillary filling needs, upstream equipment and sanitary standards. While numerous available options can complicate the selection process, they can also yield a highly efficient and cost effective solution to any given filling problem, providing that fundamental steps are taken to evaluate equipment against precise requirements.
