Benchmark for single-stage shredding

"With the XR series, UNTHA is synonymous with single-stage shredding – because we have made it a reality. And in pre-shredding and secondary shredding, our machines prove every day that true innovation begins with UNTHA. This includes the continuous development of our shredders based on comprehensive material testing and, above all, customer feedback. This enables us to adapt our shredders to the recycling of ever-changing material streams and thus respond to developments in the industry and on the market," says Stefan Scheiflinger-Ehrenwerth, CIO of UNTHA shredding technology GmbH.

The XR class – the original

The XR class shredders are powerful single-shaft shredders specifically developed for the recycling of challenging materials. They are characterized by the economical processing of different types of waste and recyclable materials, as well as high throughput and reliability. The shredders are individually adapted to customer requirements or configured accordingly, depending on the material (composition), input and output size, and the desired throughput.

"XR customers particularly appreciate the flexibility and adaptability of the machine. They can purchase a single-stage setup and adapt it later if necessary. This means that an original pre-shredder can later be used as a medium or post-shredder, or vice versa. The shredders can also be individually integrated into a wide variety of systems," explains Stefan Scheiflinger-Ehrenwerth.

• Cutting units: Depending on the input material and the desired fraction size, different cutting units can be used in the shredder. The RC cutting system was specifically developed for pre-shredding various material streams and achieving throughput rates of up to 70 t/h. The unique tooth shape tears and cuts simultaneously, ensuring optimal material feed without the need for a second press. The C cutting system achieves very precise cuts and thus a remarkably homogeneous and fine output material, even in a single stage. UNTHA's XC cutting system was developed for granulating or re-shredding pre-treated materials.
• Direct drive: The UNTHA Eco Power Drive is a wear-free direct drive that does not require any parts such as belts or shaft stubs. This means that the full power of the synchronous motors is transmitted directly to the shredding shaft via the gearbox and protective coupling. At 5–35 rpm, it is particularly slow-running, keeping dust, noise, and vibrations very low. The direct drive stands for maximum efficiency and low maintenance costs. The load-dependent speed control ensures high throughput rates and an optimal shredding process, adaptable to the respective material.
• Stationary / mobile-e: The XR class is available in 2000 mm or 3000 mm sizes and as a stationary or semi-mobile version (mobile-e), i.e., equipped with a crawler track. Both versions are identical in design and functionality, so customers do not have to compromise on shredding performance.
• Perforated screens/screen bars: The shredders can be equipped with different perforated screens or screen bars at various intervals. In conjunction with the cutting unit, they deliver grain sizes from 10 to 300 mm.
• GENIUS: With the GENIUS digital assistance system, the shredder's operation can be monitored and optimized in real time. Sophisticated sensor technology collects process data, and GENIUS calculates corresponding optimization suggestions. In addition, predictive maintenance ensures that service and maintenance work are scheduled in advance. This reduces downtime and ensures smooth operations.

The optimal interaction of all these features and the robust, low-maintenance design of the XR class achieve maximum performance, making these shredders an excellent investment with an unbeatable ROI.

Live demonstrations with the XR class

Interested parties can test the UNTHA XR intensively in their own operations—with their own material and under real conditions—before making a purchase decision. During this trial run, UNTHA experts are on hand to provide support and help achieve the best possible results.

The test runs are carried out with semi-mobile machines, which can be quickly and easily transported to interested parties and flexibly positioned on site. The technology inside the shredders is the same, regardless of whether they are stationary or mobile. This means that customers always get exactly what they have tested.

Materials: Industrial and commercial waste, waste wood and railway sleepers, metal, pulper ropes, mattresses, carpets, mixed construction waste, tires/rubber, and much more.

"We conducted a test run lasting several weeks with the UNTHA XR3000RC mobil-e at our facility. During this time, various materials, including hard plastics, foils, bulky waste, and waste wood, were shredded. Various perforated screens and machine settings were also used. The shredder itself and the support provided by UNTHA have absolutely convinced us," says Thomas Schenker, Managing Director of Schenker Industrie- und Städtereinigungs GmbH.
