What Maintenance Problems Can Occur With Big Bag Filling Systems?


Why A Big Bag Filling System?

A Bulk Bag or FIBC (Flexible Intermediate Bulk Container) filling system will save you time and increase your throughput dramatically. However, even the most well made machine needs maintenance.

If executed correctly and timeously, it’s a small price to pay for enjoying a well-functioning system. Let's discuss what you should focus on to keep your system in tip-top shape.


Preventing Avoidable Problems

You can prevent many problems by following the manufacturer’s recommendations and system’s manual. It will tell you how it should and shouldn’t be used and what it can and can’t fill. Make sure that only trained workers clean, operate and maintain it to prevent further issues from occurring.

Inspecting & Troubleshooting Your Filling System

Before seeking help from your system’s manufacturer, remember that the system’s manual can troubleshoot common issues. Making sure the system is powered off before you begin, you can try turning certain components on and off (or disconnecting and reconnecting them) to see if any connections need adjusting.

If certain system parts will require frequent replacement, keep spares in stock and ensure a staff member is trained to make the switch. This will prevent delays from having to shut down your machine and seek out external assistance. If you suspect a complex or electrical component has a problem, seek our professional advice instead of trying to resolve it yourself. Failure to do so could lead to damage and even serious injury.


Properly Maintaining Your Bulk Bag Filling System 

Regular maintenance will keep your Big Bag filling system operating properly 24/7. Remember that maintenance isn’t always to prevent or fix malfunctioning components. Here’s how you can maintain some of its key components.

  • Ideally a trained operator would complete a weekly visual inspection of the system’s fasteners, linkages and pneumatic housing. Listen to the air connections to make sure that there are no leaks. Use the operator’s manual to cross reference and confirm there is the correct psi and required air volume. This will keep the slide gate, settlers and lift platforms moving consistently. 
  • You can maintain your bagging accuracy by monitoring the product’s condition. For example your particle size could change during production due to atmospheric conditions, affecting its flow characteristics. Be aware of the product density and adjust your scale settings accordingly.
  • If you’re using vibration during the filling process, inspect the vibrator’s rubber isolator mounting pads for deterioration and check that its bolts stay in place.
  • Make sure you engage the system’s lockout valve to isolate it during maintenance and prevent an accident then
  • Drain your water separator to ensure your solenoids and actuators only get dry air. Moisture in the air supply can cause premature aging and swelling, which can impact their movement and slow it down.
  • Look for blockages or obstructions in or around the weighing platform that keep it from being level. 
  • As the electronic load cells become stretched over time, you may notice your readings becoming less accurate. It’s a good idea to recalibrate it using a known weight and instructions from your system’s manual.

Why Is Regular Maintenance Important?

Regular maintenance will protect your system from unexpected failures. However, partnering with the right supplier will ensure your system requires minimal maintenance in the first place. Contact Webster Griffin for all your Big Bag filling system supply, maintenance and servicing needs.
