Düsseldorf, Germany — Rapid Granulator AB is slowing down.
And that's the way the Bredaryd, Sweden-based recycling equipment maker likes it.
At least for its new Rapid OneCUT Pro granulater.
Rapid Granulator said slowing down the granulation speed from a standard 25 revolutions per minute to a range starting as low as 15 revolutions per minute provides advantages including creation of less dust.
The company's Rapid OneCUT PRO, which a "bandwidth" of 15 to 35 RPMs, also creates less noise and uses less energy.
"We had been working with slower speeds for many years. That has not been a priority for us," CEO Bengt Rimark said on the floor at K 2019 in Düsseldorf.
But that all changed about a year and a half ago when the company started to question the status quo when it came to the slower speed approach.
For a long time, slow-speed granulation meant processing material at 25 revolutions per minute, no questions asked. "That stock answer of we've always done it that way needed to be questioned," said Jim Hoffman, vice president of sales and marketing for Rapid Granulator Inc., the company's U.S. subsidiary located near Pittsburgh.
"The slow speed was great for certain materials. It's great to have in your portfolio," Rimark said. But the application was limited with only one speed.
