Net Weighing Systems

Bulk Bag Fillers with Net Weighing System

Concetti's net weight bulk bag weighing and filling systems are designed for high and medium speed applications and can reach a speed of 180 big bags per hour, depending on the level of automation. The products that allow the highest outputs are those that are stable, granular and free-flowing.

Tailor made weighing and filling systems for bulk bags / FIBCs

Concetti manufactures tailor made weighing and filling systems for bulk bags / FIBCs, with different levels of automation, depending on the needs of customers. The filling station integrates certified scales that weigh the product precisely and accurately. The bulk material, once weighed in the weighing hopper, is discharged directly into the bag.

The filled bulk bag is conveyed by belt/roller, with/without pallets. If the use of the pallet is required, the plant can be equipped with an automatic empty pallet dispenser.

With Concetti plants it is possible to process big bags with different loading options, including:

  • Infeed spout
  • Total bottom opening
  • Filling valve

and with different types of lifting loops (single loop or multi loop types). These systems are suitable not only for filling big bags, but also octabins (agri-bins or bulk boxes), proving to be flexible and adaptable to different needs.

Easy to clean and accessible bulk bag weighing and filling system

To facilitate cleaning operations, the bulk bag net weighers are equipped with an elevated platform from which the operator can reach the scale easily and safely.

In the case of aggressive and corrosive products, Concetti provides 100% stainless steel solutions with a very long life and highly customized solutions, thanks to precise design that takes into account all customer needs, without compromise. The aim is to guarantee the best performance with the lowest costs.

The big bag fillers of the Concetti range have various options that can be added on customer request for a tailor-made product totally suited to their needs.

Specifically, the bulk bag fillers can be equipped with:
