Bulk bags, also known as FIBC bags, have widespread industrial use. From chemicals to food ingredients, they're a trusted solution for storing, transporting, and discharging materials. However, it's important to employ correct methods of filling and emptying bulk bags.

Negligence during the unloading of bulk bags may lead to spills, damage, and exposure to dust. Sometimes, workers also get injured due to improper handling. Using proper technique ensures the safety of both people and materials.

Many manufacturers want to know: How to unload bulk bags. So let's find out a few practical methods to discharge bulk bags safely.

Common Risks When Emptying Bulk Bags

Unloading a bulk bag without proper technique and care may invite several safety and operational risks. Take a look at common hazards you might experience:

• While discharging powders or fine granules, they spread in the air as dust. The dust and airborne particles settle on equipment, clog filters, and increase respiratory-related issues.
• The uneven filling or improper support during lifting bulk bags may cause large spills and even staff injuries.
• Not using a correct bulk bag discharging process accelerates wear, leads to unexpected blockages, and increases the maintenance costs.

Switch to quality FIBC bags, use proper setup for filling and unloading bulk bags, and learn the right method to discharge materials to minimize the common risks.

Read on to know 5 effective techniques for emptying bulk bags.

How to Empty Bulk Bags Safely?

Many industry people have a common question: How to empty a big bag. So, here is a list of 5 tried and tested methods you can use to discharge materials safely:

1. Use the Vibration Method

The vibration method is best for powder and dry materials. Avoid using it for greasy or moisture-rich materials. Sometimes, material stored in the bulk bag forms small lumps. To discharge these compacted powders or granules, you can tap or vibrate sacks. This will break the lumps and let the material flow smoothly.

If you deal in components that are prone to caking or bridging. Then, a vibrating depositing plate is ideal for emptying bulk bags. Consider using jumbo bags that are compatible with standard unloading equipment.

2. The Bag Massaging Technique

This technique is effective when your bulk bag contains massage cylinders. You can squeeze or press the bag walls towards the spout. The compacted material will break and flow out easily through the discharge spout.

Remember, safety should be a primary concern. Ask your staff to wear gloves to protect their hands. And work from the sides while handling the industrial bag.

3. Try Rotating or Shaking the Bag

You can try rotating or shaking the bag gently to unload the bulk bag. The remaining material will move towards the discharge spout. This method is effective for the components that settle unevenly in the bag.

Avoid stressing the lifting loops as they can tear. Before trying this technique, maintain a distance from your bag's bottom and ensure that the bag is fully supported.

4. Try Tensioning or Bag Stretching

Try tensioning if you're looking for a technique that empty bulk bags completely. Tensioning means pulling or stretching your bag to loosen the materials. It ensures components don't get stuck inside the bag and flow better.

Make sure the bag is supported in a frame before using this bulk bag discharging process. Avoid over-stretching; otherwise, it can damage your FIBC bag's loops or seams.

5. Try Spout Pinching

This method for emptying bulk bags is suitable for powder materials or high-volume flows. You can partially close the discharge spout or pinch it to control the flow rate. Gradually, open the spout to discharge material from the bag.

This process is effective in preventing spills, dust clouds, and overfilling the receiver hopper.

Therefore, you can try any of these processes to unload the bulk bag. Consider utilizing equipment that helps in emptying bulk bags. Such as bulk bag dischargers, liners, dust control hoods, flow control valves, and spout sealing devices. All these tools & advanced bags make discharge easier and safer.
