Big bag stations tailored to your process and needs
Tamtron designs and manufactures big bag scales and big bag filling and unloading stations for commercial or non-commercial use to meet the customer’s needs.
Our versatile big bag filling and unloading solutions are ideally suited to different needs. Tamtron has supplied hundreds of them to the food, chemical, construction, and metal industries. All dry, free-flowing materials are suitable for bagging. Examples include fertilisers, animal feed, flakes, cereals, other cereal products, sugar, metallurgical concentrates (copper, nickel, zinc, cobalt, etc.), wood pellets, floor screeds, cement, circular-economy products, mulch and peat.
We provide a complete service from design to manufacturing and maintenance. We always asses the customer’s needs and clarify the initial requirements. For example, the material to be bagged must be known to choose the most suitable bag and filling method.
Key benefits

- Improve ergonomics and reduce dust with enclosed and safe solutions
- Benefit from a complete service from design to modernisation and maintenance
Big bag filling stations
Big bag filling stations are used to fill bags with materials and products. The products can be intermediate products of the process that are transferred to a temporary storage area to await final processing, or final products delivered to the customer. A bag filling station does not necessarily need weighing sensors if the bag filling level can be determined by other means.
Big bag unloading stations
Tamtron designs and manufactures big bag unloading stations for various industries and materials. For more challenging materials, the unloading stations can be equipped with, for example, clod crushers and pneumatic bag buffers to ensure complete emptying of the bags. In addition, an intermediate tank can sometimes be added to ensure a steady flow.
The design and manufacturing process always takes ergonomics and safety into account, and enclosed solutions aim to minimise dust. Easily interchangeable “unloading heads” with similar sealing solutions are available for large bags of different sizes and dimensions.
If required, the unloading stations for big bags can be equipped with a weighing system, allowing the transfer of weighing data to higher-level system and factory automation.
Big bagging scales for commercial and non-commercial use
The scale is used in commercial applications where the weighing result determines the price of a product or service. The design and operation of the scales must meet specific criteria defined by laws, directives, and other standards. In addition, the design and implementation of the automation associated with the weighing instrument is not as straightforward as that of a non-commercial weighing instrument. Therefore, the design of a commercial scale requires a different level of expertise than that for a basic process scale to meet legal requirements.
Commercial weighing
- The weighing instrument produces a weighing receipt, according to which the customer is billed:
- By specific weight (e.g. 1000 kg ± 50 g)
- Non-volume (e.g. 997 kg ± 50 g, 1001.8 kg ± 50 g), i.e. large sacks of approximately 1000 kg
Non-commercial weighing
The scale produces a weighing record, but this is not acceptable as a basis for invoicing.
Modernisation of the big bag filling scale to comply with the certificates
Tamtron modernises old big bag filling scales into automatic filling stations. Modernisation ensures that the equipment meets EU type-examination certificate requirements and the sensors used in the equipment have test certificates. We also provide maintenance and repair services for big bag filling scales.

Frequently asked questions
What types of materials can be processed with the big bag station?
The system is suitable for dry, free-flowing materials such as fertilisers, feed, flakes, cereals, sugar, cement, wood pellets, and metallurgical concentrates
Can this big bag system support commercial (trade) weighing where the product price is based on weight?
Yes. The big bag scales can be configured and certified for commercial use or supplied for non-trade process weighing, depending on your application requirements.
How are bag-filling and bag-unloading stations adapted for different bag sizes or types?
Both the filling and unloading stations are tailored to your process. The unloading units can include interchangeable heads, while the filling units are equipped with suitable collars, valves, and feeding systems for each bag type.
How do you ensure accurate weighing seamless integration of digital data at the big bag station?
The system can be integrated with weighing sensors and digital solutions such as Tamtron’s mScales service to automate data capture, reporting, and inventory management.
What modernisation options are available for existing big bag stations?
Tamtron can upgrade older big bag stations to more automated systems, improving weighing accuracy, process safety, and digital connectivity while extending equipment lifespans.
