The bio-shredder and chipper Bio 400 combines both a hammer mill and 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 intruduced directly through the mill, to be introduced throgh the chipper. The long branches and the leaves can be put directly into the mill. The machine is capable of shredding different organic materials, including wood bark, greenery, flowers manure, etc. The machine is of simple, sturdy construction, requiring easy care and maintenance. The machine can be fitted with several options, required for contractors' or public entities' use (ie axle for road transport, towing hitch, and sound insulation). A rubber belt conveyor can be fitted as an option to discharge the material even with a high moisture content.
