BHS Biogrinder The patent-protected Biogrinder is used for intensive mechanical processing of biomass before it is fed into the fermenter for the generation of biogas. The input material is crushed and defibred by means of impact and shear forces. Use of the Biogrinder accelerates the gas yield, stabilizes the overall process and allows the selection of a wider range of raw materials. The overall cost-effectiveness of the biogas plant is significantly increased.

Fermenter-friendly processing High energy efficiency In the Biogrinder, the input material is intensively crushed, homogenized and defibered to a flocculent mass, in some instances right down to the level of the cell structures. This pretreatment facilitates the uptake of nutrients by the microorganisms. The effect is particularly attractive in the case of highly fibrous biomass. Furthermore, extraneous materials, such as soil clods and stones, are also crushed without danger to the machine. The substrates remain in the Biogrinder for a very short time, so the energy applied is converted...

Feed opening  Vibration dampers  Materials are fed into the Biogrinder via a large central feed opening with a diameter of 500 mm. The machine has a relatively low height, allowing cost-effective connection to your plant technology. The machine is installed on vibration dampers to prevent the transmission of vibrations into the surrounding steel or concrete construction. Key transfer system The rotor is mounted on a vertical shaft. First of all, the material stream hits the guide blades. Beneath these, the rotor has two star-shaped levels, each of which can be fitted with a maximum of six...

A customer in Southern Germany uses a BHS Biogrinder (75 kW) installed on a biogas plant (capacity 900 kWel) for processing corn silage, grass silage, green rye and WCS. The biogas plant (capacity 1,200 kWel) of a customer in Northern Germany is equipped with a BHS Biogrinder (75 kW). It is used for processing grass silage, shredded corn cobs, cattle and horse dung, green rye and WCS. In Saxony, a BHS Biogrinder (55 kW) on a biogas plant (capacity 300 kWel) processes grass silage, cattle and horse dung, and WCS.
