HOW IT WORKS & BENEFITS

Processors around the world use bulk bags to pack, store, and transport materials. Our range of Spirofil bulk bag filling equipment makes filling bulk bags safer, easier, controllable, contained, and cost effective.

Continuous development of our weighing and filling stations gives processors the choice of standard equipment or customized to suit access, height or hazardous considerations. Our bulk bag filling stations are also more versatile than many on the market – they can be adapted for use with rigid IBCs, drums, or octabins.

How it Works

Our C Series bulk bag fillers are simple and easy to operate.  The basic sequence of operation is as follows:

  1. Place the bag loops of empty bulk bag over the support arms or bag support hooks.
  2. Attach the bag spout or liner over the inflatable neck seal.
  3. Adjust the height of the bag support arms (if selected).
  4. Inflate the neck seal to secure the bag spout or liner.
  5. Inflate the bag or liner.
  6. Commence filling by weight or volume.
  7. Apply vibration (if required).
  8. When the bag is filled to its target weight or volume, deflate the neck seal and tie the bag spout or liner closed.
  9. Engage the automatic loop release (if selected).
  10. Remove the filled bulk bag by forklift, pallet jack or roller conveyor (depending on your application).

Benefits

Wide Range of Applications

Spirofil bulk bag fillers offer the widest range of applications and are used extensively across an equally wide range of industries including food, pharmaceuticals, chemicals, plastics, building, and construction.

Versatility

Many standard operating features are included in our bulk bag weigh fillers, enabling the processor to begin immediate production without the need for extra equipment. In addition to the many built-in features, a full range of options is provided, allowing many other operations to be performed from the same machine.

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.

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.

Optional Components
Vibratory Compaction/De-Aeration SystemELECTRIC: For use in applications where vibration is required & no roller bed is used.
Twin electro-mechanical vibrators are mounted below the platform & provide vibration in an up & down direction for compaction & de-aeration of the product as the bag is filled. The two vibrators are mounted side by side, effectively canceling lateral vibration.

PNEUMATIC: For use in XP applications where vibration is required & no roller bed is used.
A single linear piston type pneumatic vibrator is mounted below the platform & provides vibration in an up & down direction for compaction & deaeration of product as the bag is filled.

FINGER-STYLE: For use in applications where vibration is required & a roller conveyor base is present.
A floor mounted unit comprised of a steel frame with 'fingers' is mounted on pneumatically operated bellows. Fitted to the 'finger' assembly are two (2) electro-mechanical vibrators to provide vibration in a vertical plane direction to compact & de-aerate the product during the filling cycle.

When vibration is required during the filling cycle the pneumatic bellows raise the 'finger' assembly through the powered roller conveyor & lift the pallet from the conveyor to ensure that the necessary vibration is applied to the filling bag & none is lost in the support structure of the machine.
Access PlatformThe access platform, with left or right-side access, is fabricated from heavy angle & bar material with tubular handrails & checker or grid footplate.

It can be constructed from carbon/mild steel with Steel-It paint or 304 stainless steel and includes a back plate for mounting a control panel.
Automatic Height AdjustmentAutomatic Height Adjustment of the fill head & support frame is available via an electric screw jack.
Fill Nozzle with Dust Extraction PortThe 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.

An optional inflatable neck seal is also available (see Item H).

Product Contact Surfaces: Stainless Steel Only
3-Position Slide Gate Fill Control ValveA stainless steel slide & aluminum frame complete with a pneumatic actuator set up for three-position bulk/dribble/closed feed operation.

The valve is attached to the customer's upstream equipment & is connected to the bulk bag filler via a flexible isolation boot.
Knife Gate ValveThe 2-position knife gate valve is pneumatically operated with stainless steel contact metal construction.

The two positions allow for closing off the fill head, eliminating any dribble from the flex during carriage travel while there is no bag in place.
Pneumatic Bag Neck SealUsed in conjunction with the standard filling nozzle, the Pneumatic Bag Neck Sealing Assembly provides a positive & reliable method of sealing the bag spout to the filling nozzle.

The neck seal system also works with lined bags.

The inflation assembly consists of a stainless steel filling nozzle, food grade rubber sleeve, a pneumatic valve, a regulator, a filter, a gauge & a pneumatic hand operated switch mounted on the bulk bag filler frame for inflating & deflating the neck seal.
Bag Spout Retaining RingUsed to provide a positive seal with loose liners, over sized inlet spouts or duffle top bulk bags.
Sampling PortProvides a means for pulling a small sample of material as the bulk bag is being loaded.
Filling Head Product SpinnerDesigned to ‘throw’ product to the extremities of the bulk bag during the filling cycle.

This action negates the product’s angle of repose in the center of the bag ensuring complete filling of the bulk bag.

The unit is fitted to the inside of the filling nozzle by a three-arm spider.

The motor rotates the stainless steel spider fitted with throwing plates which radiates the product to the outside of the bulk bag when it hits the rotating disc.
Retracting Bag Support HooksThe remote pair of bag loop support hooks pneumatically retracts to facilitate the hanging of the empty bag from the operator’s location.
Automatic Bag Loop ReleaseFour small pneumatic pistons retract the lever on the bag loop securing latches by depressing a lever activated switch mounted on the bulk bag filler frame.

Eliminates the need for the operator to manually release the four loop latches.
Bag/Liner Venturi Air InflatorThe inflator is attached to the vent spigot of the filling nozzle & does not interfere with standard venting or extraction methods.

It includes a pneumatic hand operated switch mounted on the bulk bag filler frame for inflating the bulk bag.
Bag/Liner Fan Air InflatorThe inflator is attached to a two-way valve that interfaces with the vent spigot of the filling nozzle & does not interfere with standard venting or extraction methods.
Inflation is facilitated by means of an electric fan to inflate the bag.
Motorized Roller Conveyor
(On Filler Base)
The roller conveyor section is mounted on the filling platform & is used to remove filled bags on pallets.

The conveyor is motorized with rollers to move loaded bag/pallets onto the takeaway conveyor.

Use of the Automatic Loop Release is required to ensure proper operation of the system.
Gravity Take Away Roller Conveyor
(Beside Filler)
For accumulating bulk bags on pallets.
A section of roller is mounted next to the filler.
Powered Roller Conveyor

Filling Bulk Bags, Boxes or Drums

Processors need to respond quickly to customer demand and be able to supply product in other kinds of containers such as rigid IBCs, drums, octabins and other IBCs. With the addition of special adaptors, this can be achieved using the same filling platform, providing a versatile, multi-purpose machine.

Really Big Jobs

36,000 tons in 27,000 bulk bags in Alaska, all in only 14 weeks!  Two Spirofil bulk bag fillers were delivered and operational in 6 weeks.

 

Complete Systems & Semi-automated Filling Systems

This is where we truly excel.  We take care of everything from concept to commissioning.

 

A semi-automated filling system gives large volume users the benefit of continuous operation without having to stop and unload each bag or gaylord.  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.
