HOS shredders are available in five sizes.
HOS heavy-duty pipe shredders from Slatersville, R.I.-based Herbold Meckesheim USA
are designed to smoothly and efficiently reduce large, thick-walled plastic pipes to chips about 2.4 to 3.9 inches square.
Herbold Meckesheim USA, a subsidiary of Herbold Meckesheim Germany, designs, manufactures and installs size reduction equipment and wash-line systems for the plastics industry. The company specializes in the recycling of industrial and postconsumer plastics.
Available in five sizes, the shredders can process up to 3,400 pounds per hour and can handle pipes as large as 9.8 feet in diameter, according to the company.
A high-torque hydraulic ram holds a horizontally oriented pipe against a moving cutting plate that is 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 tha
n those of a typical heavy-duty pipe granulator and the unit uses less energy and requires less maintenance, according to the company. 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, the company adds.
