Efficient substrate processing

Fermenter-friendly processing

• Enhanced uptake of nutrients for micro-organisms through intensive shredding, homogenization and defibration of the input material
• Particularly effective in the case of highly fibrous biomass
• Extraneous materials, such as soil clods and stones, are also crushed.

Greater variety of raw materials

• Raw materials that were previously difficult or impossible to decompose in the fermenter can now be processed with ease after processing in the Biogrinder.
• Wide range of applications: corn silage, grass clippings, green/organic/animal waste, sugar beet, corn straw

High energy efficiency

• Very short substrate retention times
• Nearly all the energy applied is converted into crushing capacity and not heat
• Further energy savings result from the reduced need for chopping during harvesting, reduced agitator use in the fermenter 

Stable fermentation process

• Homogenization facilitates transport of substrates
• No deposits build up in the fermenter

Continuous process

• Continuous operation simplifies technical integration of the machine into the overall plant 
• Different sized Biogrinders available to ensure optimum throughput rates for biogas plant

Feed opening

The Biogrinder has a large feed opening, which allows the machine to be easily fed with different materials.

Rotor

The rotor is mounted on a vertical shaft. The material stream first connects with a distribution cone. Below this, the rotor has two levels, each of which can be fitted with a maximum of two pivot-mounted hammers. Crushing is carried out primarily between the rotating hammers and the stator strips on the machine casing. The arrangement of the hammers is variable, so that the rotor can be optimally configured for the specific task.

Distribution cones

The distribution cone feeds the inserted material to the hammer levels. This prevents possible clogging of moist or light material in the feed area.

Hammers

 The carbide hammers welded onto the base are optimized to deliver a long service life. Due to the flexible bearing, even extraneous solid materials, such as stones and soil clods, can be crushed easily. Modification of the hammer configuration can be achieved in minutes.

Stator bars

The stator strips and wearing plates are fastened from the outside by means of bolts. The wearing parts can thus be easily exchanged and are optimized for long service life.
