HOW IT WORKS & BENEFITS
How It Works
Our patented coned densification table provides tamping & densification to ensure proper ingredient fill. The table assembly consists of a truncated pyramid welded on a frame with two integral electro-mechanical vibrators.
The CTE moveable carriage assembly raises & lowers placing the bottom of the bag into contact with the cone table. This forces ingredient into the bottom corners of the bulk bag during filling, providing maximum densification & a flat-topped, stable package.
Cone Table Densification Explained
Geometry creates stable base
1. Build a stable base
The cone table’s shape directs product to the bottom corners of the bag to create a stable foundation.
Efficient energy transfer
2. Transfer maximum energy
The cone table makes direct contact with the bag resulting in maximum vibration energy transfer.
Bag stretches up to 5%
3. Stretch the bulk bag
A bulk bag typically spends 50% of the filling cycle hanging from its loops and not in contact with the cone table. During this time the bulk bag stretches, increasing volumetric efficiency and assisting with bag stabilization. A stretched and densified bulk bag will not slump and will hold more product.
Flat top removes angle of repose
4. Removes the angle of repose
Almost any dry bulk solid has an angle of repose which is the angle formed by the peak of material produced when pouring a dry bulk solid. To produce a flat-topped bag, the horizontal top of the cone table pushes up a column of product every time it comes in contact with the bag. When the cone table is removed from contact with the bag, the angle of repose is flattened.
Best Densification and Bag Stability
The CTE Bulk Bag Filler features patented cone table densification ideal for powders, granules or pellets that are easily aerated and/or difficult to compact. When the bulk bag is properly stretched and the material is deaerated with a flattened angle of repose, the result is a very safe and stable bag.
Unmatched Bulk Bag Stacking
The CTE is the only bulk bag filler available that produces filled bulk bags that are so stable they can safely be double stacked within the filler itself as well as in storage areas. This allows end users to maximize operator productivity and minimize storage and warehousing costs.
The CTE Bulk Bag Filler utilizes hang weighing and delivers repeatable best-in-class weighing accuracy of +/- 1-2 lb.
Industry Benchmark High-Speed Bagging
The CTE Bulk Bag Filler delivers unmatched bulk bagging rates of 30-35 bags/hr. with weighing and more than 40 bags/hr. with pre-weighing! These bag fillers are often configured with automated filled bag removal to maximize bagging rates and operator productivity.
Multiple Bulk Bag Types
The CTE Bulk Bag Filler can fill lined or unlined bags, with or without an outlet spout. Bulk bags can also be filled with or without pallets.
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. Can the filling system be automated?
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.
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.
Our CTE bulk bag fillers can operate as stand-alone units or part of a semi-automated filling system.

Complete Bulk Bag Filling Systems & Semi-automated Filling Systems
This is where we truly excel. We take care of everything from concept to commissioning.
A semi-automated bag filling system gives large volume users the benefit of continuous operation without having to stop and unload each bag or gaylord/box. Pallets are automatically fed to the filling rig and the bags are looped onto pneumatically operated hooks. Once filling is completed, the loops are automatically released and the bag is then moved along the line by a powered take-off conveyor.
The drawing above illustrates a dual semi-automated CTE bulk bag filling system. It includes 2 CTE bulk bag fillers, slip sheet dispenser, operator access platform, automatic bag removal conveyors and gravity roller conveyors.
