The new generation Bio 90 bio-shredder is the ideal synthesis of various organic and vegetable waste shredding system solutions. It implements a single feeder chute for feed-in operations plus a double chipping and shredding system providing for screen-adjusted chipping size. The Bio 90 bio-shredder features either a petrol engine or an electric, three-phase engine. The shedding system consists of two parts: the first, formed by two chipping blades, allows cutting wooden and fibreous materials such as linden, and willow; the second, featuring 6 reversible mobile hammers, shreds products such as leaves, hedges, soil, and kitchen waste. The finess of the output is adjusted by way of a auto-cleaning sieve. The chip discharge position is ensured by means of an adjustable casing.
