Dual-Shear®

M120 Two-Shaft Shredder

The Dual-Shear® M120 from SSI Shredding Systems is a low-speed, high-torque, two-shaft, rotary shear shredder engineered and built to efficiently process a wide variety of difficult to shred materials.

Dual-Shear® M120 industrial shredders are versatile machines commonly employed in bulky item reduction, product destruction or pre-conditioning (primary shredding) where particle size variation is acceptable. Output consists of “strips” the width of the cutters - usually 25 - 76 mm (1 - 3 in). Dual-Shear® M120 industrial shredders are engineered with drive and cutter configurations specific to your production requirements.
