Pellet mill for biomass and sunflower hulls
Achieve high-speed, continuous production of durable pellets from varied materials, ensuring flexibility and precision in demanding processing conditions.

Processes Biomass into Pellets and Briquettes
The Pellet Mill RWPR from Bühler Group is engineered for robust biomass and animal feed production. Designed to withstand demanding conditions, it efficiently transforms finely ground wood, sunflower hulls, and grains into high-quality pellets and briquettes. With its integrated machine control system, it optimally conditions materials using water and steam, maximizing throughput and activating natural binders. Capable of continuous, high-speed operation, the RWPR features automatic lubrication and an inlet bypass to prevent blockages, ensuring smooth production. Particularly suitable for biomass processing and agricultural producers, it handles diverse raw materials and end-products ranging from wood heating pellets to kibble for pets and whole wheat flour. With optional materials and engineering support, it offers customization to meet specific production needs.
