UNTHA ZR dual shaft shredder

The UNTHA ZR two shaft shredder is suitable for waste, wood and metal shredding. It has been engineered for multi-shift, continuous pre-shredding, even when handling difficult materials some would consider economically unshreddable.

The machine’s low speed, high torque drive means it can process severe-duty applications with ease, for a high level of plant availability. The modular, quick-change cutting table design presents versatility.

The ZR2400H, for example, has been engineered for the high throughput, rough shredding of bulky waste, C&I waste, waste wood, MSW, mattresses, carpets, railway sleepers, bales and rolled goods. Available as a static or mobile machine with crawler tracks, the goal for this model is volume reduction (90% <300mm), material breakdown for further treatment, and alternative fuel production. The cutting system is therefore suitable for cement plants, operators in the biomass and energy recovery industries, MRFs, sorting and waste disposal firms.

The ZR2400W is a metal scrap shredder that is also suitable for the processing of WEEE and large domestic appliances. Again, the goal is to achieve a rough material breakdown (90% <300mm) for downstream sorting, making this machine suitable for metal processors, recyclers and aluminium and metal manufacturers.

The ZR’s independent, bi-directional shaft rotation means the aggressive cutters grab, shear and liberate material in forward and reverse, for a machine action that always shreds.

Both pre-shredders are also supplied with the UNTHA Eco Power Drive with water-cooled synchronous motors — an energy-efficient concept which is designed to reduce energy consumption by up to 75%.
