Bag weighing machines: which weighing technique suits powders, granulates and pellets?

You know the feeling: a production line that falters due to inaccurate weighings. Too much product in a bag unnecessarily costs you a lot of money. Too little product immediately leads to complaints from your customers. Choosing the right weighing technique is therefore crucial for your profitability.

Why the type of product determines your weighing technique

Not every material flows in the same way through your machine. Powders behave completely differently from coarse pellets. That is why a standard solution is rarely the best choice for your facility. You need a bag weighing machine that suits your specific bulk material.

The best approach for fine powders

Fine powders such as flour dust up extremely quickly. This causes product loss and a contaminated working environment. A screw dosing system is often the most efficient solution here.

• The system doses the powder with extreme control.
• This prevents unnecessary and dangerous dust development.
• The weighing is always accurate to the gram.

Smart weighing of granulates and pellets

Granulates and pellets generally flow much more easily. Think of plastic pellets or animal feed. For these products, we often work with a flap dosing system or a vibrating trough. This guarantees high speed without sacrificing precision.

Gross weighing or net weighing?

When filling, you face an important technical choice. Do you choose a gross or net weighing system?

• With gross weighing, you weigh the product directly in the bag.
• This is ideal for products that quickly stick or get stuck.
• With net weighing, the machine weighs the product in a weighing container.
• This provides much higher speed in your packaging line.

Frequently asked questions about bag weighing machines: which weighing technique suits powders, granulates and pellets?

Which weighing technique is most accurate?

This depends entirely on your specific product properties. For free-flowing pellets, a net weigher with flap dosing system is very precise. For powders, screw dosing offers the very highest accuracy.

How do I prevent dust formation when weighing powders?

Always choose a closed dosing system with a dust-tight filling spout. Good extraction around the bag weighing machine is also absolutely essential. We are happy to advise you on the right setup for your facility.

Can I weigh different products on one machine?

Yes, that is certainly possible with the right settings. Modern machines easily store different product recipes in the software. However, make sure you clean the machine thoroughly when switching products.
