Tree chipper (wood chipper, chipper, cutting machine), Lviv region.

Disk wood chipper is a two- or three-knife chopping machine for grinding wood waste from sawmills, branches and tops of trees, stumps, waste from woodworking industries. Such a technique is indispensable for the utilization of wood waste, processing wood residues into chips of a certain size, for further use as raw material, or for obtaining thermal energy in gas generators and boiler plants. allowing to obtain a really high efficiency by the pyrolysis method
The optimal diameter of the material for felling is up to 160 mm. The output size of the chip is from 13 to 40 mm (possible independent adjustment to a larger or smaller side). Depending on the operating conditions, the cutting machine can be equipped with replaceable output pipes of different lengths - from 1.5 to 2.5 meters, rotating 360 degrees.(//tractor-service.com)
The drive of the felling machine can be implemented in two versions - either electric with a stationary installation, or through the power take-off shafttractor (necessary equipment with a power of at least 40 hp).
The supply of material to the cutting knives of the disc can be carried out by self-adjustment due to the angular arrangement of the receiving hopper or with the help of a hydraulic feeding system, which makes it possible to make the design simpler and more reliable, to increase the safety of working with the equipment and its efficiency.
