A robust, high volume pre-shredder with the lowest whole life running costs in its class. Low speed. High torque. Maximum performance.
With an aggressive and modular cutting table, the ZR can process everything from metals and LDAs, to C&D waste, wood and more. Versatility lies at the core of this powerhouse.
UNTHA’s Eco Power Drive reduces energy costs by up to 75%, and high uptime with easy maintenance means this machine pays for itself. Strong performance. Smart savings.
Bi-directional shaft rotation means the cutters grab, shear and liberate material in forward and reverse, for continuous operation and a high quality, homogenous output – perfect for downstream equipment.
Achieve a high-performance rough shred of:
Guaranteeing a homogenous output material (90% <300mm), the ZR is ideal for:
Available as a static or mobile machine, this model is engineered for the high throughput, rough shredding of bulky waste, C&I waste, waste wood, MSW, mattresses, carpets, railway sleepers, bales and rolled goods. Perfect for volume reduction (90% <300mm), material breakdown for further treatment, and alternative fuel production. The ZR2400H is used by cement plants, operators in the biomass and energy recovery industries, MRFs, sorting and waste disposal firms alike.
Available as a stationary machine, this model is the perfect metal scrap shredder, and excels also in the processing of WEEE and large domestic appliances. The goal is to achieve a rough material breakdown (90% <300mm) for downstream sorting, making this the ideal machine for metal processors, recyclers, and aluminium and metal manufacturers.
Efficient electric drive with water-cooled synchronous motors for 75% less energy consumption than standard diesel hydraulic drive.
Wear-free direct drive reduces maintenance costs as belts and shaft stubs aren’t required.
Load-dependent speed control for high throughputs.
Quick-change cutting table for pre-shredding versatility.
Supplied with intelligent condition monitoring tool, UNTHA GENIUS.
Low speed, high torque for high resistance against non-shreddable items.
Bi-directional shaft rotation to grab, shear and liberate material in forward and reverse, for continuous operation.
Large in-feed space ideal for even bulky materials.
We have many hoppers to suit different in-feed methods, from a wheeled loader to conveyor and grab. Talk to us about your requirements.
UNTHA’s ZR mobil-e is supplied with a fully-integrated discharge conveyor – with varying specifications available – and overband magnet for savvy metal separation.
Get inside your shredder's brain! This real-time condition monitoring tool uses several in-built machine sensors to analyse and optimise machine performance. Displaying up to 100 data points, UNTHA Genius is designed to improve shredder productivity, minimise maintenance and downtime costs, and proactively alert the operator to potential faults - irrespective of their location.
We have hundreds of cutters, screens and other OEM parts in stock and available for immediate UK dispatch.
