Weigh belt feeder for low-density materials
Optimize high-volume feeding accuracy for light materials while reducing your production footprint and maintenance efforts with an innovative gravimetric dosing system designed for continuous operations.

Conveys and Doses Low-Density Materials
The MAMMUTHUS LIGHT from HASLER Group is a robust industrial extractor weigh feeder designed to transport and dose low-density materials like Solid Recovered Fuels with precision. This equipment uniquely combines a metal apron conveyor with an integrated weighing system, ensuring reliable operation in high-flow industrial settings. Suitable for applications across cement production, hydrometallurgy, water treatment, and more, it supports continuous processes by handling high volumes of materials with an impressive accuracy of ±1%. Equipped with an impulse sensor and double chain traction, it ensures consistent operational performance and reduced compaction. The system’s automation is enhanced through the SCMIII flow control system, allowing for seamless integration into existing production lines. Maintenance is simplified with built-in inspection doors, and its fully enclosed design protects both the material and the working environment. Customization options and engineering support are available to meet specific industrial requirements.
