M55 Two-Shaft Shredder

SSI’s Dual-Shear® M55 is a low-speed, high-torque, two-shaft, rotary shear industrial shredder designed to efficiently process a variety of difficult materials.

Dual-Shear® M55 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® M55 industrial shredders are engineered with drive and cutter configurations specific to your production requirements.
