Untha America, Hampton, New Hampshire, has released a two-shaft shredder, the ZR, engineered for multishift, continuous preshredding – even when handling difficult materials some would consider economically unshreddable, the company says. Its debut follows 24 months of research and development, including prototype trials in Europe.

According to the company, the shredder promises the lowest life cycle costing (LCC) for waste, wood, electronics and metal shredding in its class.

Untha says the machine’s low-speed, high-torque drive can handle severe-duty applications with a high level of shredder and, ultimately, plant availability. Its modular, quick-change cutting table design also offers versatility.

The ZR2400H has been engineered for high throughput when rough shredding a variety of bulky material, commercial and industrial material, wood scrap, municipal solid waste, mattresses, carpets, railroad ties, bales and rolled goods. Available as a static or mobile machine with crawler tracks, the goal for this model is volume reduction, material breakdown for further treatment and alternative fuel production, Untha says. This cutting system is suitable for cement plants, the biomass and energy recovery industries, material recovery facilities (MRFs), sorting and waste disposal firms.

The ZR2400W is designed for metal scrap shredding and also processes e-scrap and large domestic appliances for downstream sorting. The company says it is ideal for metal processors, recyclers and aluminum and metal manufacturers.

The ZR preshredders feature independent, bidirectional shaft rotation to grab, shear and liberate material in forward and reverse.

The Untha Eco Power Drive is designed to reduce energy consumption. 

Both preshredders also are supplied with the Untha Eco Power Drive with water-cooled synchronous motors, which the company says can reduce energy consumption by up to 75 percent.

Sales Director Peter Streinik says, “With the ZR, we’re talking a reliable powerhouse that pays for itself. Like all our shredders, the innovation is engineered for long service intervals, easy maintenance, safe operations and high uptime. But what will really make it stand out in its class is the ability to tackle difficult materials, at low cost.

ZR shredders are supplied with Untha Genius, the company’s condition-monitoring system that provides operators with access to their shredder’s performance data, in real-time, from any device.

Hubert A. Schwarz, head of processing and process development at the Austrian tooling company Schaufler, which trialed the ZR prototype for 12 months during the machine’s R&D phase, says, “The most important advantages of the ZR are versatility—the unit can shred both large, coarse [nonferrous] metals and composites; fast, easy and efficient cleaning and maintenance; and low energy consumption—compared to other manufacturers, we’re saving $82,000 in energy costs a year as a result of using the ZR.”
