SHREDDING | TECHNOLOGY
raises power transmission by up to 20%, according to the company.
Customers can choose from several drive concepts to adapt the machine to their own process- es. A hydraulic drive is particularly suited to applica- tions with frequently changing loads. The robust drive ensures high torques with a low kW output. The classic electromechanical direct drive ensures high energy efficiency and easy maintenance. Wursi, based in Spain, shreds around 1,500 tonnes of PE and PP into regranulate every month, using two Weima W5.14 single-shaft shredders on its recycling line. It first processes sorted plastic waste manually and feeds it into the two shredders – which shreds the material to 30-100 mm pieces. The shredder is designed for demanding plastic
applications. A V-rotor with a diameter of 500 mm and a length of 1,400 mm ensures uniform shred- ding even with tough materials. A Siemens PLC control system with touch panel allows precise adjustment of operating parameters. A hydrauli- cally opening screen basket and inspection flap help to reduce downtime during maintenance or screen changes. Wursi uses interchangeable screen segments that can react flexibly to material differences – an advantage with changing polyole- fin streams, says the company. The original Untha XR3000C mobil-e, launched
in 2016, was a breakthrough in mobile waste shred- ding, being the first of its kind to offer an electro- mechanical drive on a mobile chassis. Untha says the 2026 version is part of an evolution of the XR platform, and introduces significantly upgraded drive technology as well as increased flexibility for heavy-duty waste shredding. The XR class can be used for pre-shredding bulky waste, waste wood, metal, pulper ropes or plastic bales.
Drive technology Specifically, in addition to the standard Eco Power Drive (synchronous), the Untha XR3000C now offers an asynchronous drive engineered for extremely heavy-duty applications while maintain- ing high energy efficiency. It also features a new, self-sufficient power generator system that regu- lates the shredder’s operation, even in locations without a direct grid connection, while integration with the MyUNTHA customer platform provides real-time condition monitoring, predictive mainte- nance, and access to the Genius digital assistance system. A new communication interface allows the shredder and material handlers to react to each other in real-time, optimising the feeding process to prevent overloads and maximise throughput. Recycling company RDG was recently looking

for a shredding solution suitable for various plastics (composites) and applications, enabling flexible responses to different material flows, when it discovered the Untha offering. “We needed a shredder that could handle plastic-metal compos- ites and came across the Untha XR3000C mobil-e,” said Franz Kobleder, Managing Director of the RDG Recycling Group. “This shredder completely won us over. We can efficiently pre-shred our materials and thus prepare them for the subsequent process- ing steps.” In May, Vecoplan presented its VIZ 1300 high-performance shredder at Plastpol, the trade fair for the plastics and rubber processing industry in Kielce, Poland. The material diversity that plastics recyclers must deal with can be mastered with the VIZ 1300, according to the company. This is because the shredder is available with variable rotor and blade configurations as well as a range of screen sizes, which means it “adapts flexibly to virtually any plastic material and any application requirement”, said Vecoplan. A particular highlight of the VIZ 1300 is the option to equip the machine with automatically adjustable counter-knives. Normally, operators need to manually readjust the cutting gap regularly to maintain consistent shredding quality. The automatic counter-blade adjustment performs this task fully automatically and without manual intervention. Vecoplan says this significantly reduces the time required and guarantees a consistently high output quality, regardless of the operator’s level of experience. Users have two options for the type of drive that
can be fitted. The gearless HiTorc drive generates torque directly and comes without any wear parts such as couplings, belt drives, and flywheels. Alternatively, the ESC belt direct drive is available. Vecoplan says both options are designed for maximum efficiency and minimal maintenance.
