HOS Heavy-Duty Pipe Shredders from Herbold, Smithfield, R.I., reportedly smoothly and efficiently reduce large, thick-walled, plastic pipes to chips approximately 2.4 to 3.9 in.²  Available in five sizes, the shredders can process up to about 3,400 lb/hr and can handle pipes as large as 9.8 ft dia.

A high-torque hydraulic ram holds a horizontally oriented pipe against a moving cutting plate studded with blades.  As the vertical cutting plate travels back and forth across the end of the pipe, it slices off chips.  The chips fall onto a conveyor belt, which can transport them to a cutting mill for further size reduction.

The grater-like design means the blades of an HOS Shredder wear much more slowly than those of a typical heavy-duty pipe granulator, and the unit uses less energy and requires less maintenance.  HOS Shredders are even suitable for abrasive materials, such as fiberglass-reinforced piping.  They produce little noise, and each model is equipped with a covered feed trough.
