The Task at Hand

Processing of forest residues
Forest residue is the collective name for treetops and branches that accumulate when harvesting timber and for rootstocks that accumulate during clearing. Depending on the material, the logistics and the customer requirements, forest residue can be processed by low or high-speed shredders, often in combination with screening machines.

Production of wood chippings
Wood trunks not suitable for material recycling can be processed into high-quality wood chippings by a Chippo chipper. The high-speed Axtor shredder can also act as a high-performance chipper when used with fixed tools.

  • Process Steps

    Shredding with low-speed

    The low-speed Crambo shredder is used if the quantity of contraries increases, such as stones in forest residue and rootstocks. Direct fuel production or pre-shredding for further treatment - the output quality is depending on the selected screen basket.

  • Process Steps

    High-speed shredding

    A fuel with a more coarse structure can be generated from forest wood residue by shredding with the general-purpose Axtor wood shredder. Simply exchanging the hammer tool for a static chipping cutter with reversing blade converts the Axtor into a powerful chipping machine for logs.

  • Process Steps

    Drum chipper for logs

    Logs not used for material recovery are processed into high-quality wood chippings by the Chippo. The mobility of the machines allows processing near to the source. The family starts with a tractor-operated drum chipper, includes in the mid  performance range variants with lorry drive and ends with a large-scale chipper rated at more than 700 HP.

  • Process Steps

    Quality increase with screening

    Subsequent separation by Komptech star screens, drum screens or wind sifters brings a marked increase in quality – fine fractions are passed to the composting process and contraries are separated off using Fe separation or wind sifting.

  • Process Steps

    Fuel without stones

    The Stonefex improves fuel quality by removing up to 90 percent of stones and insert materials. Biomass processors profit from better customer acceptance of their fuels, higher sale prices, and the ability to make a saleable product from material contaminated with stones.
