Quad®

Q70 Four-Shaft Shredder

SSI’s Quad® Q70 is a low-speed, high-torque, four-shaft, rotary shear industrial shredder designed to process a variety of materials and produce a small, consistent particle size.

Quad® Q70 shredders are known as multi-purpose shredders because they are designed to work like a two shaft shredder when the internal screen is removed, or as a sizing shredder that's able to shred, liberate and reduce a wide range of commingled materials without overly thick metals, in one pass. Four shafts in the Quad® Q70 shred and recirculate material within the machine until it is sized small enough to pass through a removable screen set immediately below the cutters.
