Belt feeder for alternative fuels
Maximize fuel efficiency with this belt feeder designed for seamless dosing of alternative materials, ensuring precise, consistent flow and optimal integration into continuous high-energy combustion processes.

Feeds and Weighs Lightweight Alternative Fuels
The GRAVIT LIGHT from HASLER Group is a robust industrial belt feeder engineered for precise dosing of lightweight alternative fuels, such as fibers, plastics, and shredded tires, in continuous operations. It incorporates a dual weighing system to ensure stable inflow and consistent flow rate, achieving accuracy within ± 0.5%. Designed for integration into production lines across various industries like cement, fertilizers, and metals recycling, it supports high throughput up to 150 m³/h. The fully enclosed unit minimizes dust emission and enhances operator safety, with sophisticated belt cleaning systems to maintain efficiency. An optional ATEX version is available for environments prone to explosive dust. With minimal maintenance needs, the GRAVIT LIGHT ensures autonomous operation 24/7, optimizing energy use with features like adjustable tension systems and self-centering belts. Customization options include spillage conveyors and feed screws, and it can interface with HASLER’s SCMIII controller for seamless operational control.
