Feeders for powders/packaging materials
Precision and control for the most complex powders
The dosing of powdery materials is one of the most delicate challenges in industrial processes: powders tend to compact, form bridges and cavities and often exhibit irregular flow behaviors. For this reason, choosing the right dosing technology is essential to ensure continuity, accuracy and reliability in the long term.
Key benefits
Our depositors for powdery materials are designed to ensure a homogeneous flow, avoiding clogging phenomena and ensuring high process repeatability even in the presence of light, abrasive or cohesive dust.
Thanks to their modular and compact design, these feeders can be easily integrated into new or existing systems, adapting to different production layouts with the possibility of being configured for gravimetric or volumetric dosing, depending on specific needs.
Why choose our powder feeders?
- Controlled, consistent flow even with difficult materials
- High dosing accuracy
- Easy cleaning and material change
- Compatibility with various interfaces and automation systems
- Easy integration into new or existing production lines
In particular, we prefer to use co-rotating twin-screw feeders, which offer maximum reliability in powder handling thanks to their ability to break bridges and keep the material in constant motion. This system ensures maximum smoothness and accuracy of feeding, minimizing the risk of downtime and improving the overall efficiency of the process.

Characteristics
AT16 is our dosing machine for maximum dosing precision, for difficult materials.
Unit designed and built for frequent production changeovers and fast cleaning times. The station
dosing system can be used as a single station or as part of a dosing line
dosage.
- The modular design of the AT16 provides high flexibility to meet the needs of the
the different and changing process requirements. - All parts in contact with process materials are made of stainless steel
corrosion-resistant. - Possibility to replace the complete dosing station without the use of tools
in seconds. - The AT16’s vibration damping system eliminates disturbances such as
vibrations, typical of process areas. - Compact design allows up to 8 assembled dosing stations to be used
from a radius of only 0.5 meters.

Characteristics
Compactness and precision for dosing powders at different flow rates
The AT20 and AT35 feeders are designed to offer reliability, versatility and continuity of flow in the dosing of powdery materials, with the utmost attention to the prevention of bridges and interruptions.
Both models are equipped with a multi-wing agitator that keeps the material in constant movement inside the hopper, ensuring perfect fluidity and optimal filling of the dosing screw. This ensures a stable and linear flow, even with materials that are difficult to handle.
The mechanical inlet and outlet connections are designed for the installation of different accessories, so as to easily adapt the dispenser to specific application needs and achieve the highest levels of precision and performance.
AT20
- Ideal for modest flow rates and applications where extreme precision is required with dusty materials.
- Perfect for processes where fine dosing control makes all the difference.
AT35
- Designed to handle higher flow rates, while maintaining the same compactness and reliability.
- Suitable for industrial processes with medium to high production requirements.
Common features:
- Multi-wing agitator: eliminates the risk of bridging and ensures continuity of flow.
- Modular and compact design: easy integration into existing plants or multi-dosing systems.
- High application flexibility: possibility of customization with dedicated accessories.
- Compatible with volumetric and gravimetric dosages.
Both models can be used as stand-alone units or integrated into multiple dosing systems, easily adapting to dynamic and changing production environments.

Characteristics
Large capacity, compactness and durability for the most demanding applications
The AT70 doser is the ideal solution for those looking for high dosing rates without sacrificing compactness and construction solidity. With a capacity ranging from 80 to 8,244 l/h, this model is designed to handle large volumes of material while maintaining precise flow control.
Thanks to the integrated horizontal agitator, the material is kept constantly moving inside the dosing chamber, eliminating the risk of bridging and ensuring uniform filling of the feed screw. This ensures stable and continuous dosing, even with complex or slightly cohesive powders.
Constructed from corrosion-resistant materials, all surfaces in contact with the product are made of stainless steel, offering reliability and durability even in the harshest industrial environments.
Strengths of the AT70 feeder:
- Large dosing capacity: from 80 to over 8,000 l/h
- Compact and powerful: maximum efficiency in a small space
- Integrated horizontal agitator: avoids the formation of bridges and ensures continuity of flow
- Resistant and durable: made of stainless steel for maximum reliability over time
- Easy to integrate: ideal for both stand-alone applications and complex multi-metering systems
The AT70 feeder is the perfect choice if you need to combine power, precision and robustness in a single machine.
