11.2 Bulk Bag Filler Cases - Finak Thought
High efficiency is the biggest advantage of bulk bag loading systems over open-mouth bagging systems.
Many industrial solid granular materials must be processed several times to meet the final sales requirements. Therefore, these materials must be transported from one processing company to another. The need to package and transport large quantities of solid materials becomes particularly strong.
The volume of the common open-mouth bag is 25-50kg, and they need to be sealed, which is very inconvenient for both senders and pick-up materials. In contrast, the ton bag has many advantages in meeting the needs of bulk material transportation well, so the bulk bag is widely used, and at the same time, the sales of bulk bag filling equipment and ton bag unloaders are also growing.
Learning more about bulk bag fillers and choosing the right bulk bag conveyor. It will greatly improve your production efficiency. Then let’s start from here.
▎1. What is the Bulk Bag
The bulk bag is a flexible transport packaging container which belongs to the medium-sized bulk material packaging container. Also known as the big bag, jumbo bag, FIBC. We often use the bulk bag to load bulk materials.
The common ton bag loading capacity between 0.5T-2T, and volume between 500-2300L, can greatly improve the loading efficiency. They are mostly made of polypropylene, polyethene and other polyester fibres, so it has a strong load-bearing capacity and can be used repeatedly.
1.1 Types of Bulk Bags
There are rich bulk bag designs to meet different loading requirements, and customers can choose different types of bulk bags. Different bulk bags have different inlets, discharge ports and lifting straps.
1.2 Advantages of Bulk Bags
- Flexibility
The bulk bag is made of flexible material, making it possible to fill large amounts of free-flowing material and easily carry high-strength loads while keeping its structure intact.
- Lightweight
Using lightweight textiles to make the bulk bag can significantly reduce transportation costs.
- Space saving
Empty bulk bags can be folded into smaller sizes for easy storage without taking up space.
- Recyclable
When ton bags are damaged, they can also be recycled and used to produce new ton bags.
- Efficient loading and transportation
Working with the automatic bulk bag filling machine can greatly improve the efficiency of filling and transporting bulk materials. Fill more material per unit time and stack more material during a single transport.
▎2. What is the Bulk Bag Filler
The bulk bag filler can efficiently and safely fill bulk materials into bulk bags. It is also known as FIBC filler, big bag filler, jumbo bag filler, or tonne bag filler.
It is large automatic packaging equipment integrated with electronic weighing, automatic bag removal, and dust removal, with a high degree of automation.
It is suitable for mineral, chemical, building materials, grain, fertilizer, and feed industries for bulk loading applications. It can pack solid granular or powder materials, such as feed, grain, seeds, flour, salt blocks, minerals and chemical materials.
Wxtytech’s bulk bag filling machine can weigh 500-2000 kg. The filling speed range is 1-60 tons/hour, and the weighing accuracy is ≤ ±0.2%. No matter the scope of your bulk material packaging project, we can customize the right bulk bag loading solution for you.

▎5. Integration of Bulk Bag Fillers
As large automatic packaging machinery, it is composed of complex mechanical and electrical structures, including metal frame, bag hanging and clamping system, inflation and exhaust system, feeding and weighing system, hydraulic lifting system, conveying system, electrical control system, etc.
Bulk Bag Filler Frame
The bulk bag filler frame provides a stable mechanical structure, ensuring the machine’s reliability and productivity. If you choose top weighing bulk bag filler, all frames have 4 metal pillars to provide absolute stable support for bulk bags.
If you choose the bottom weighing bulk bag filler, when you use the forklift, we can provide you with a cantilevered support frame consisting of 2 metal pillars that will not affect the forklift in any way.
Bulk Bag Hanging and Clamping System
It has a safe, reliable and convenient bag hanging and clamping system for bulk bags. It is suitable for all sizes of bulk bags and can help operators to hang bags quickly. Moreover, the bag clamping system can tightly connect the bags to the discharge to avoid material leakage.
In the top weighing tonnage bag scale, the bag hanging system is controlled by the cylinder with weighing function. The hooks are also controlled by cylinders that can prevent the bags from slipping and ensure safety. After filling, the bag is released automatically, which is convenient and fast.
In addition, it also has the vibrating function. The movement of the cylinder drives the ton bag up and down in the vertical direction, which makes the material distribution more even and ensures the accuracy of weighing.
The bottom weighing bulk bag filler uses the manual bag hanging system, which finds a balance between practicality and cost. It also can meet the needs of customers well.
Bulk Bag Conveying System
After filling, you need to move them and complete the next step. There are several options for bulk bag transport systems.
You can choose to use the pallet and forklift to transport bags. If you use the top weighing filler, there is no need to add anything to the bottom. If you use the bottom weighing filler, then a concave platform is required at the bottom.
We also offer a powered roller conveyor system. After filling, the tonnage bags will fall on the roller conveyor and keep moving forward.
You can also choose the belt conveyor to provide forward power for the bulk bags. Besides, we can also integrate the load cell at the bottom of the belt conveyor.
Bulk Bag Weighing System
We have different weighing systems depending on the type of bulk bag fillers.
The top weighing bulk bag filling machine is weighed by the cylinders. Four cylinders are connected to the hooks, which lift the ton bags and make them suspended, and the data of the change of the cylinders is used to calculate the exact weight by computer.
The load cell of the lower weighing tonnage bag scale is at the bottom of the platform. When the material is continuously filled into the tonnage bag, the huge weight squeezes the bottom platform, thus causing the load cell at the bottom to deform and release an electrical signal, which is used by the computer to derive the exact weight.
To meet the high-speed packaging requirements (60t/h), wxtytech proposes the solution of a weighing hopper.
A weighing hopper is added to the top of the bulk bag filler. When the material reaches the preset weight value, the machine automatically opens the hopper gate, and the material flows into the bulk bag. After filling, the hopper gate is closed.
Filling, weighing, and loading bags can be done simultaneously, which greatly saves time.
Bulk Bag Filling System
To complete the process of filling jumbo bags successfully, you should have a complete solution to solve various difficulties.
First is the feeding system. Load the bulk bag open-mouth over the outlet, then activate the switch. The entrapment mechanism will firmly connect the two to form a sealed space.
Then turn on the rising system starts. The blower instantly blows a large amount of wind into the bulk bag, which makes bags expand and open, so that the material can fall into the bag evenly.
In addition to this, there is a dust removal system. Excess material will be sucked by the dust removal tube, filtered by the dust removal system and returned to the feed inlet. It avoids the waste of material and ensures a clean environment.
Electrical Control System
The automated bulk bag filling equipment has high automation and user-friendly operation. They can operate automatically after the completion of setting and calibration. All the control and display functions are integrated into the electric control cabinet.
The start switch is located on the side of the discharge so that employees can easily start the machine after hanging the bags.
▎6. Types of the Bulk Bag Filler
To meet rich bulk material packaging needs, we are also constantly optimizing our technology and designing different types of bulk bag scales to cover all customer needs fully.
6.1 Filling Method
Different solid materials have different characteristics and need to do some individual design. Currently, there are three feeding methods, screw feeding, gravity feeding, belt feeding and vacuum feeding.
- Screw Feeding Bulk Bag Filling Machine
If you need to pack solid powder materials or materials with small particle diameters, we recommend using the screw feeding way.
The screw blade rotates to push the material forward. It can effectively avoid the blockage of powder materials and ensure smooth operation.
- Gravity Feeding Bulk Bag Filling Machine
If you need to pack large particles of solid materials, we recommend using the gravity feeding way. The structure is simple and stable, relying on the gravity of the material to fill the material.
- Belt Feeding Bulk Bag Filling Machine
If your material is sticky, such as fertilizers. We recommend using the belt feeding way. Using a moving belt to feed material into the weighing hopper. All the material falls on the belt and will not stick to the inside of the machine.
- Vacuum Feeding Bulk Bag Filling Machine
When you pack fragile and lighter materials, you can use the vacuum feeding way. Using air pressure to feed the material into the bulk bag without damaging the material.
6.2 Weighing Method
Due to the large size of the bulk bag filler, it is often limited by the dimensions of the production site. Two different weighing methods can effectively reduce the height of the machine.
- Top Weighing Bulk Bag Filler
Most bulk bag filling machines use the top weighing method, where four vertical cylinders are connected to hooks that grab the four carrying handles of bulk bags. It uses the change of cylinders to calculate the weight, but then the height of the whole equipment will be higher.
At the same time, the vertical cylinders can also vibrate bags. It moves the bulk bag up and down in a vertical direction so that the material can fall more evenly in the bag.
- Bottom Weighing Bulk Bag Filler
Many customers’ production sites have low heights and can’t use the top weighing machine. Therefore, we installed the weighing system on the bottom of the platform where the bulk bag is placed. The filled bags squeeze the load cell to get the accurate weight.
Without the vertical cylinder, the height of the complete machine is greatly reduced and can meet most factories’ site needs.
6.3 Bulk Bag Filler Hopper
In order to improve the packing speed, you can use the weighing hoppers.
- Net Weight Bulk Bag Filling Machine
It is equipped with the weighing hopper on the conventional bulk bag filling machine instead of using the cylinder to weigh.
The material is continuously filled into the hopper, and when the weight reaches the preset value, the hopper gate opens, and the material flows into the ton bag. Loading bags and feeding can be done simultaneously, so the packing speed is very fast, up to 60 bags/hour.
However, we should note that the height of the net weight bulk bag scale becomes higher due to the addition of the weighing hopper.
- Gross Weight Bulk Bag Filling Machine
We named the usual bulk bag filling machine a gross weight bulk bag filling machine. They are not equipped with the weighing hopper and weighing by the cylinder.
Because feeding and loading bags cannot be done simultaneously, the packing speed is not very fast and can reach 30 bags/hour.
▎7. Features of the Bulk Bag Filler
- Stable steel structure with four pillars, able to withstand the large weight.
- The overall height can be adjusted to accommodate various sizes of bulk bags.
- Equipped with the dust removal system to prevent materials from polluting the environment and save materials to improve production efficiency.
- Equipped with the bag-raising system, the computer-controlled blower blows up the bulk bag, allowing the material to be filled into the bulk bag.
- Equipped with a vibrating bag system, the material distribution is more even by making the bulk bag move in the vertical direction.
- With a stable mechanical and electrical structure, it can run stably for a long time, is easy to operate and has a low maintenance cost.
▎8. Accessories for the Bulk Bag Filler
To improve the convenience of the bulk packaging process, customers can also choose from some optional equipment to improve production efficiency.
8.1 Bulk Bag Conveying System
After filling, we need to move the filled bulk bag away. There are many options for this.
You can choose to use a pallet and then remove it with a forklift. You can also use a tonnage bag conveyor system, including a belt or a round roller conveyor.
After filling materials, the bulk bag falls on the conveyor and is sent to the next packing part by the conveyor, which is very convenient and fast.
8.2 Bulk Bag Sealing Machine
If you need to close the bulk bag, you can choose the optional heat sealing machine. When the filling is finished, the conveyor will send bags to the closing, and the operator will heat seal the bulk bag.
8.3 Automatic Pallet Dispenser
We used forklifts to place and deliver pallets in the past, but this was less efficient. Therefore, we can use automatic pallet distribution systems and round roller conveyors, and the process of distributing and transporting pallets is all computer-controlled and fully automated, greatly improving productivity.
▎9. Applications of Bulk Bag Fillers
You can use the bulk bag filling equipment when you need to fill and weigh bulk solid materials. It is suitable for different industries, including chemical, grain, cement, construction, coal, fertilizer, feed, ore, rubber, rubber and plastic, and metallurgy.
Chemical Industry：Pigments, Plastic Pellets, Carbon Black, Polymers & Resins, Extra Fine Chemicals, Chemical Fertilizers, Other Chemicals
Mineral Industry：Gravel, Coal, Litter, Clay, Aggregate, Sand, Cement, Fly Ash, Talc, Limestone, Concrete Mixes, Crushed Stones
Feed Industry：Manure, Mulch, Peat Moss, Soil, Bark, Compost
Agricultural Industry：Malt, Seed, Corn, Bean, Fertilizer.
Food Industry：Salt, Rice, Sugar, Spices, Flour, Grain, Milk Powder, Barley, Wheat
▎10. Workflow of Bulk Bag Fillers
This is the complete workflow of the bulk bag filler.
Solenoid valves control the bag clamping and hooking structure. First, hang the bag on four hooks, load the inlet of the ton bag on the outlet of the machine, activate the bag clamping device, the bag is clamped, and the four hooks are closed.
Then contracts the cylinder and lifts the bag, and the bulk bag scale automatically clears the bag’s self-weight and completes the weight correction process.
At the same time, the bag rising system starts, and the fan blows the ton bag completely open. Then the feeding starts, and the material flows into the bulk bag.
The air cylinder keeps descending and weighing at the same time. When the weight reaches the preset value, the hook is automatically released, and the clamping mechanism is automatically released to complete the packing process.
Finally, use the automatic conveyor or forklift to remove the bulk bag.
