Bulk bag unloading equipment is a core component of an efficient supply chain. By automating the process of removing goods from bulk bags, these machines increase productivity and safety. Bulk bag unloaders might, however, encounter problems that could cause disruptions to operations and inefficiency, just like any other mechanical equipment.
Custom Bulk Bags is a leading manufacturer and supplier of flexible intermediate bulk containers (FIBCs) in South Africa. We produce up to 3.5 million bulk bags per year and our products can safely hold between 500kg and two tonnes of material per bag. Our products can be tailored to fit your unloading equipment, making the entire process seamless.
How to use bulk bag unloaders
This equipment has one simple task; to discharge material from bulk bags into storage bins, hoppers, or conveyors. They are used in many different industries, including construction, chemical manufacturing, agriculture, and food processing.
Bulk bag unloaders usually lift, move, and pierce the FIBCs so that the contents can flow out using a combination of pneumatic and mechanical methods. While these machines make the supply chain faster and more efficient, they can encounter some issues. There are three common problems that businesses may have when using bulk bag unloaders.
Typical problems with unloading equipment
- Bulk bag leaking – While this is not necessarily a problem with the machine itself, leaking from bulk bags can occur when using unloaders. Damaged bulk bags, misaligned unloaders, or too much weight on the bag are some of the possible causes of this. Workers need to ensure that bulk bags are in good condition before placing them on unloaders and starting the discharge process.
- Inaccurate bulk bag placement – For the unloader to operate properly, bulk bags must be placed precisely and consistently. Incomplete emptying, spillage, or damage to the bulk bag can result from misalignment. Workers must take extra care when attaching bulk bags to unloading equipment to prevent damage or safety hazards.
- Inaccurate weighing techniques – To keep track of the quantity of material discharged, some unloaders are fitted with scales. Overfilling or underfilling storage bins due to inaccurate weighing can cause inefficiencies and possibly quality problems.
Taking care of these problems
Before bulk bags are filled, they need to be closely examined. Look for any signs of damage or wear and tear, such as rips or punctures, before putting them on an unloader. Replace any damaged bags since they may have leaks and compromised stitching. Always make sure the bulk bag is firmly and centrally located on the unloader’s platform. To ensure uniform placement, use alignment methods or guidelines.
In addition, routine maintenance on bulk bag unloaders will ensure that they work properly. Check for signs of strain, lubricate moving parts, and replace any broken components on these devices as soon as issues are found. If your bulk bag unloader has a weighing system, make sure it is calibrated on a regular basis to maintain its accuracy.
Consider making changes to bulk bags when ordering new ones. Depending on the situation, changing the bulk bag design itself may help you solve various problems. For instance, using a strengthened base or including a discharge spout can enhance handling and minimise the chance of leaks.
Optional extras for bulk bags
When ordering your bulk bags, you may want to consider the following optional upgrades to improve the fit between bulk bags and unloading equipment:
- Bottom closures – Certain bottom closures can reduce spillage and provide regulated discharge, such as iris valves or slide gate spouts. Full-bottom discharge bags are fast but they may not be the best solution when paired with unloading equipment.
- Lifting loops – Spec your bulk bags with the right lifting loops that will fit your unloader. This will not only make the task easier and faster, but it will also improve safety.
Choosing the right bulk bag manufacturer is an important step too. This will guarantee that your bulk bags work well with your unloading machines. Custom Bulk Bags provides a large selection of tailored FIBCs that will meet your unique requirements. With your overall operational goals, the kind of materials you handle, and the particular needs of your unloading equipment in mind, our experts can help you choose the best bulk bags.
