Total Evacuation

Bulk Bag systems fully evacuate the surge hopper being discharged and the conveyor line. This limits cross contamination of multi-ingredient systems. Complete transfer of material also ensures accurate transfer of single or multiple ingredients, maximizing quality with minimal waste.

High Reliability and Ease of Maintenance

Bulk Bag systems allow for easy cleaning and maintenance through easy to maintain equipment and associated accessories.

Mobile and Custom Configuration

Self-contained Bulk Bag systems are available pre-engineered and configured on castor mounted frames for mobility within your plant or forklift moveable as a standard option. Packages include many options from the options list.

Designed, Constructed and Finished to Industrial and Sanitary Standards

Bulk Bag Filling systems are available in carbon steel with durable industrial finishes or stainless steel to standards required for food, dairy and pharmaceutical applications.

Bulk Bag filling systems successfully transfer an enormous range of products, both free-flowing, clumping, powdery or otherwise, across many industries. They are noted for their efficiency and ease of operation.

In the food, pharmaceutical and fine chemical industries, a virtually unlimited range of materials can be handled. Applications include salt, sugar, flour, starch, spices (food) or yeast granules, glucose, talc, paracetamol (pharmacy) etc. Other sectors using this system include the chemical, plastic, water and mineral industries, PVC resins, lime, silica sands, soda ash, iron oxides, calcium carbonates, quartz, fly ash, talcs, detergents etc.

All installations for conveying and feeding have the ability for single or multiple point feeding and discharge points allowing huge flexibility with minimal additional componentry. The units can be ordered as basic units and can have options added to the units at a later date when factory expansion requires. Discuss this with your local Bradwood Packaging Sales representative.

To protect your Workers from OH&S issues involved in placing and removing bulk bags, the Bulk Bag Filling system should be designed to keep them safe at all times.

Upper and lower bulk bag unloader frame combine to safely support and contain the bulk bag and its materials. The bulk bag is loaded into the bag frame by a dedicated hoist, forklift, crane or persons, depending on speeds required.

Forklift Loading

The Frame of Bulk Bag Filling System has been designed with a standard capacity of 2000 kg and is constructed of 100mm RHS. The upper frame section has 1000mm of height adjustability to accommodate the different size bags.

Hand Loading

Hand loading the empty bulk bags is the most common method of placing the bags. The bags placement has been designed, with a number of options to help the operators improve the speed of filling more bags.

Cranes

A complete lower frame is available for applications where customers have an existing Crane Hoist Monorail System.

The bulk bag is attached to a bag hanger for raising and positioning the bag into the Bulk Bag Filling support frame. All bag hangers allow easy attachment of the bag loops while securely holding the bag in place within the Bulk Bag Filling System.

Bag hangers can add options to retain bulk bag liners and prevent bag liners from extruding through the discharge spout into the downstream process equipment during bulk bag filling.

Bradwood Packaging systems go beyond simple bulk storage systems with further componentry for a complete materials handling solution from start to finish. Other products in our range include bulk bags fillers / emptiers, storage bins and hoppers, rotary valves, mixers, diverter valves, bin activation, augers, mechanical & pneumatic conveyors, bucket elevators, batch weighers, packaging machinery. Please see our videos of our bulk materials equipment as well as our turn key plant solutions.

The operator has various options to access the discharge spout of the Bulk Bag Filling system, depending on the bag style and dry material flow characteristics. The Bulk Bag Filling System has been designed to give user-friendly access to open and seal the bulk bag’s spout. It provides dust-free and complete material discharge from the bag as well.

A wide variety of options are available to integrate bulk bag unloaders with material conveying systems and downstream process equipment. The material flow characteristics and the specifics of the customer’s bulk bag filling application dictate the type of bulk bag discharger interface utilized.

Surge Hopper

Surge Hoppers with various capacity, can be utilised to provide continuous material supply while removing empty bags and loading full bags into the Bulk Bag Emptier. The inlet to the surge hoppers are typically connected to a bag spout interface option while the discharge is often connected to a conveying system.

Agitator Hopper

This U-shaped hopper has a mechanical agitator which eliminates the potential of material bridging or forming a rat hole above the inlet to material conveying equipment. The design of the agitator draws the material away from the sides, directing it through the centre discharge on a consistent and reliable basis.

Combination Hopper

The combination hopper allows filling of small bags, sacks, drums, and other containers in addition to bulk bags. Combination hoppers can be fitted integral dust collectors or tube stubs for connection to centralized dust collection systems.

Size Reduction Equipment

Rotating shaft(s) with staggered breaker bars deagglomerates materials as they pass through stators to reduce materials to a conveyable particle size.

Feeder Systems

Volumetric and loss-in-weight feeders are utilised to control the transfer of materials directly from the bulk bag discharger to conveying or downstream process equipment.

• Sack/Box tip and bulk bag combination stations
• Rigid bin and bulk bag combination stations
• Bulk bag and rigid IBC filling equipment

Bradwood Packaging offers more solutions in a wide range of Bulk Bag filling or filling, vacuum pressurised systems, to mechanical based feeding and conveying.

We take safety seriously, because we know accidents can have deadly and expensive consequences. Keeping your workers safe increases your productivity.

The safety of bulk bag filling operators during the entire sequence of handling, loading, untying, filling, retying, and removing bulk bags is paramount in bulk bag filling design. From safety interlocks to structurally sound discharger design and construction, process equipment operator safety is considered during every step of the bulk bag filling process.

All Bradwood Packaging machinery complies with the latest local and international standards. Dust-free operation is highest in mind when supplying any filling system, simplicity is still kept in mind for fast and safe operation but with the durability to last.

Safety Interlock Switches

Our machinery is fitted with safety interlock switches to prevent the operator from accessing moving mechanical equipment.

Bag Present Sensors

Bag present sensors disables moving mechanical equipment unless the bulk bag is in the proper location for discharging.

Exceeds Structural Standards

The Bradwood Packaging Bulk Bagging Filling System has been designed and built to exceed Australian Standards.

Frame-mounted Hoist Controls

The Hard-wired controls are mounted on the lower framework of the Buk Bag Filling System. The Hard-wired controls prevents the operator from standing under a bulk bag when it’s ready positioned for discharging.

Integrated Dust Collector

Protect surrounding facilities, equipment, and operators from escaped airborne material, reduce maintenance and ensure ongoing operation.
