Efficient substrate processing TRANSFORMING MATERIALS INTO VALUE

TRANSFORMING MATERIALS INTO VALUE The Company BHS-Sonthofen is an owner-operated group of companies specialized in machinery and plant engineering. The group is headquartered in Sonthofen, Germany. BHS provides technical solutions for mechanical process engineering with a focus on mixing, crushing, recycling and filtration technologies. With more than 300 employees and several subsidiaries, BHS-Sonthofen maintains a global presence. More than 100 Years of Experience in Crushing Technology We built our first crushers over a hundred years ago for the aggregates industry. In addition to...

BHS Biogrinder The 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 mashed by means of impact and shear forces. Use of the Biogrinder accelerates the gas yield and stabilizes the overall process. It also greatly expands the selection of raw materials and significantly increases the overall cost-effectiveness of the biogas plant.

Fermenter-Friendly Processing High Energy Efficiency The Biogrinder intensely crushes the fed material and homogenizes and defibers it 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 great 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 that virtually all the energy applied is...

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 Cone ^ The...

Biogrinder in Germany The operator of a German biogas facility implemented the Biogrinder RBG 08 (55 kW) as the core component of the plant. The facility processes surplus field crops, green rye, corn and rape straw, GPS as well as horse manure containing straw. Biogrinder in a mobile processing facility The mobile processing facility delivers a cost-efficient alternative for applications with changing locations. The Biogrinder RBG 08 (75 kW) is the centerpiece of the installation. Further plant components, such as a feed hopper, control system as well as feed and discharge technology, are...
