Our screw technology is constructed and designed for the most difficult substrates. The type 350 has been specially developed for small biogas plants. With the 300 mm auger blades, feeding substrates such as solid manure and grass silage is no problem. Our screw technology type 500 is the ideal feeding screw technology for larger biogas plants that mainly process solid manure, maize straw, grass silage and organic waste.
