Granulator more powerful, has larger chamber

Issue: April 2018

Rotoplex granulators Ranging in power consumption from 15 kilowatts (kW) to 500 kW, granulators in this Hosokawa Polymer Systems (HPS) series use a patented cross-scissor cut to quickly chop up all kinds and shapes of plastic waste, including film, lumps, scrap and flakes. It is built from solid spheroidal graphite cast iron; special designs are available.

What’s new? The addition of a larger model, the Rotoplex 125/125, that sports a larger-diameter rotor chamber for higher cutting efficiency. The machine, also known as the 125/125 RO, has a 49-inch-diameter chamber, allowing room for 12 rotor-knife rows and nine bed-knife rows. Compared with a traditional granulator configuration, which employs three rotor-knife rows and two bed-knife rows, the 125/125 RO boasts an 18-fold increase in cutting efficiency.

Benefits More cuts per rotor revolution, high throughputs, low wear and little heat generation. It also offers lower power consumption per pound of ground material.
