Our invention makes it possible to produce the same quantity of wood chips as ordinary machines (all machines on the market) in half the time and with half the energy consumed, as well as the best quality and with a longer blade cutting time. (twice as long as the ordinary machine cutting time). The system of drum and reduction motor, and round and fixed platform with a bearing cylinder for blades, allows for a planing operation (scraping between wood and blades) in one direction only which allows to produce the same quantity of wood chip by consuming half of energy and also half of the time which constitutes our invention.
