Double Shaft(Metso 4500/6500)

Metso FineShredder for High Efficiency System for high recycling rate

Patented Multi-edge rotor cutting technology and Hydraulic Power System

The Metso FineShred range consists of two-shaft shredders for continuous material input. The Metso FineShred units can be used in a wide range of different applications including difficult materials such as sticky bitumen, fabrics and foams. Particle sizes of 10-100 mm are obtainable depending on the screen size applied. Two counter rotating shafts fitted with knives specially selected for the individual applications ensure a high degree of flexibility of the units. The unique design of the cutting area ensures minimal friction on the shaft. In combination with the continuously adjustable rotor speed, the variable cutting frequency and the optimal selection of screen sizes a very homogeneous output with a minimum content of fine fractions can be achieved. The hydraulic drive of the shafts guarantees an impact resistant and resonance free power transmission. All together a minimum of wear and energy consumption is secured.
