Designed specifically for continuous high volume recovery of the toughest materials, Polymer Systems` heavy duty machines are precision machined with heavy steel plates and stress relieved weldments throughout. Massive construction of the cutting chamber, rotor and drive assembly provides maximum rigidity, allowing close knife settings without fear of misalignment or machine damage due to shock loads or continuous operation.
Only Polymer Systems` granulators have a clear, unobstructed feed opening equal to rotor diameter for maximum performance through every inch of the cutting circle. This unique design maximizes granulator capacity, eliminates bottlenecks at the entrance to the cutting chamber and dramatically increases effective screen area for fast throughput. A special sound-deadening composite material is used for hopper walls on all Press Side, Large Part, Shurfeed 2000 and Heavy Duty granulators.
If you work with electronics or are in an industry that requires you to remove insulation from wires frequently,
then you would do well to invest in a high quality automatic wire stripper.
Electrical contractors routinely create scrap metal products such as wire and cable,
aluminum conduit, cable tray, copper pipe, and even switchgear on the jobsite,
but they may not realize the value of these materials can significantly boost their bottom line.
The keys to getting the highest price for these items are knowing exactly how to collect and sort the material and bringing it to the proper scrap processing facility.
