No other bulk bag filler uses our patented high-vibration cone densification table. The Spiroflow CTE bulk bag filler offers industry-leading weighing accuracy (+/- 1-2 lbs.), densification, bagging rates, and bag stability.
Our Cone Table Elite (CTE) Bulk Bag Filler is one of the most versatile and capable bulk bag fillers in the industry. Unlike other fillers, the CTE bulk bag filler features the company’s patented cone table densification system which densifies material in the bag, increases bag stability, and bulk bag filling throughput.
Consider the CTE Bulk Bag Filler when you require maximum bulk bag densification, bag stability, bag stacking capabilities, weighing accuracy and the highest bagging rates.
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.
The cone table’s shape directs product to the bottom corners of the bag to create a stable foundation.
The cone table makes direct contact with the bag resulting in maximum vibration energy transfer.
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.
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.
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.
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.
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.
The CTE Bulk Bag Filler can fill lined or unlined bags, with or without an outlet spout. Air or nitrogen can be used in the filling process. 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.
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.
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.
Our CTE bulk bag fillers can operate as stand-alone units or part of a semi-automated filling system.
The CTE Bulk Bag Filler can be configured with a variety of components. Based on your application a Spiroflow engineer will recommend one of three CTE designs.
