The straw mill SD is specially adapted to the grinding of straw due to its special geometry. The result is high throughput and low energy consumption. Low bulk densities and very large volumes of processed straw pose no problems for the Straw Mill SD. The straw can be easily broken down to the typical fineness of 10 mm or less (depending on the specifications of the fermenter manufacturer) and is thus optimally prepared for anaerobic digestion. The dry straw is transported pneumatically in an energy-efficient and low-wear manner.
Like all our mills, the straw mill SD meets the highest industry standards and is designed for continuous use over many years. The straw mill SD series consists of two housing sizes for motorization from 90 kW to 250 kW drive power.
Once the straw has been broken down, we can efficiently and reliably mix it with your fermentation substrate or slurry so that it can be fed directly into the biogas plant after processing.
In straw mono-digestion, the Impra system can additionally be used as a stock preparation system to further break down the fibres in the process.
