The bio-shredder Bio 200 combines both a hammer mill and a disc blade chipper in one. The fineness of the finished product can be adjusted by way of different sized screens. The lateral chipper is placed in a separate chamber from the hammer mill. This allows large logs, that cannot be introduced directly through the mill, to be introduced through the chipper. The long branches and the leaves can be introduced directly into the mill. The machine is capable of shredding many organic materials, including wood bark, greenery, etc. The machine can be customised with several options, required for contractors' or public entities' use (ie road axle, towing hitch, and sound insulation). The machine is of simple, sturdy construction, requiring easy care and maintenance.
