Technical equipment
The working group has a well-equipped technical centre for the practical development of topics. The equipment for pre-treatment processes includes, for example, various drying techniques and milling systems such as hammer mills and cutter mills on a laboratory and pilot plant scale. Various mixing technologies in different sizes are available for homogenisation and additive treatment. Pellet and briquette presses as well as granulation technology are used for agglomeration and compaction. Various analytical instruments are available for evaluating mixing quality, particle sizes or compaction success. In this context, the working group also works very closely with the well-equipped analytical laboratory of the DBFZ.
With this technical equipment and more than 15 years of experience in mechanical biomass processing, the working group is an excellent partner in the field of production, development, characterisation, pre-treatment and additivation of solid biofuels or precursors for various applications.
