Double-stage rotary weigh feeder for precise powder dosing

Ensure consistent dosing and precise weighing of challenging fine-grained or powdered materials in continuous industrial processes, enhancing control and efficiency in variable conditions like humidity and material behavior changes.

Accurately Doses and Weighs Fine-Grained Materials

The TWIN ROTAWEIGH from HASLER Group is a double-stage rotary weigh feeder designed for precise dosing and weighing of fine-grained and powdered materials. It incorporates a dual-chamber horizontal cellular impeller system, allowing for continuous industrial weighing and dosing, even when material properties vary due to humidity, temperature, or composition changes. This feeder excels in a range of applications, from cement and chemical industries to food processing, enabling reliable delivery of products such as Portland cement, calcium ammonium nitrate, and powdered sugar. With flow rates from 2 to 800 m³/h, it offers high-precision measurement with a ±0.5% accuracy. The TWIN ROTAWEIGH can be seamlessly integrated into existing production lines, utilizing an SCM control module for streamlined operation. It boasts a compact footprint with its vertically aligned input and output, and it is available in multiple configurations to fit diverse operational needs. Additionally, this equipment features high-temperature resistance and full sealing to ensure durability and performance in demanding industrial environments. Maintenance is straightforward, allowing on-site servicing to minimize downtime.
