Untha, Kuchl, Austria, has launched its third series XR waste shredder. The Untha XR was first brought to market as a robust preshredder that was designed to process a myriad of municipal, commercial and industrial wastes in readiness for the alternative fuel production market. 

Whilst aesthetically the machine has the same construction as its predecessors, it is the internal workings of the technology that have been refined to enable the XR to handle a wider range of input materials.

Different cutter configurations, torque settings and motor modifications mean that one day the shredder can be producing a 2-inch-minus specification biomass fuel with low fines output from waste wood, for example. The next it could be manufacturing a high quality SRF with homogenous 1-inch-minus particle sizing, before going on to achieve a 3-inch gasifier material.

“We have always known the capabilities of the XR are virtually limitless,” says Peter Streinik, Untha’s head of the waste shredding division. “We are a problem-solving team hungry to engineer ever-smarter solutions for the global waste market as it continues to push new boundaries. But, as with many technological industries, the process takes time.

“The evolution of the XR has therefore been an iterative process,” he continues. “This third series machine has been 3 years in the making and has taken months of trials and $1,200,000 to perfect. But now we have a truly remarkable shredder with flexibility like no other equipment in the marketplace. It can tackle everything from ordinary commercial waste through to incredibly complex applications like pulper ropes. And we’ve designed the machine so that it achieves the throughputs achieved by a higher speed shredder, with far lower wear rates, operating costs and energy consumption.

“Whether clients opt for a static or mobile machine, the beauty of the new XR is the breadth of its capabilities,” continues Strenik. “The build and rigidity of the kit, along with its in-built protection from unshreddables, has opened up a whole new world of opportunity. We’re even configuring one machine that gives excellent recovery rates when using optical sorting equipment within a MRF (material recovery facility) or fuel preparation line—this would have previously only been possible using two shaft technology. 

“The waste industry is, quite rightly, continually demanding more, and this shredder addresses that yearn for more flexibility, more uptime and more profits.”

More than 40 XRs are now in operation in alternative fuel production plants worldwide.
