Energy-efficient shredder for alternative fuel production using waste wood, pulper ropes etc.
The XR class is a high-performance shredder for alternative fuel production that may be used as a pre-shredder or a single-phase shredding solution. Extremely low-maintenance and maintenance-friendly, it offers a very long service life. Spare parts are usually available within 48 hours and the remote maintenance option further ensures the smooth operation of your plant.
The XR class is a very energy-efficient and low-speed, single-shaft shredder that was specifically designed for shredding coarse and medium-sized municipal solid waste (MSW), commercial and industrial waste (C&I) as well as for recycling scrap wood and bulky waste. It is often used as a pre-shredder in a comprehensive system or simply as a single-stage shredding concept to produce refuse derived fuel (RDF) for the calciner.
Size reduction with low operating costs
Minimal operating costs paired with maximum performance make this waste shredder a strong partner that stands out for its forward-thinking technology, such as the UNTHA Eco Drive concept that lowers energy consumption by 75% compared to standard electro-hydraulic drive options.
State-of-the-art synchronous motors achieve maximum efficiency, making the UNTHA Eco Drive one of the most energy-efficient drive systems on the market. In addition, maintenance costs may be reduced to a minimum as the unit is free from pulleys, hydraulic pumps and shaft stubs. Where higher throughputs – and therefore also higher rotor speeds – are required, there is the option of integrating a safety coupling that will separate the rotor from the drive if a foreign object is detected.
Flexible waste shredder for different material
To fulfill your individual requirements, the XR class is available with a ripper, cutter or X-cutter system. The combination with our patented XR screen bars or different-size screen systems makes a fraction size from 400 to 30mm possible. The final throughput will depend on the type of material and the screen diameter and ranges from 10t/h to 70t/h.
All rotors are wear-protected thanks to welded Hardox plates, making them particularly resistant against abrasive materials.
Our experienced project engineers are at your disposal to assist with the planning and implementation of your project.

"Ripper" cutting system
The "Ripper" cutting concept is a "ripping system" for coarse shredding of material sizes ranging from 400 mm to 100 mm. The exact material size is defined by screen bars or a perforated screen. The teeth of the ripper can be used 2 times and can be welded onto the outside of the machine after their service life has expired. Thanks to the welded on Hardox plates the rotor is protected against wear and therefore has a very long service life.
"Cutter" cutting system
Our cutting system is equipped with cutters, thus allowing for output material sizes of 130 to 50 mm.The exact material size is defined by a perforated screen. An internal pusher shoves the material against the rotor with the cutting inserts which can be used 4 times. Thanks to the welded on Hardox plates the rotor is protected against wear and therefore has a very long service life.

“UNTHA has worked collaboratively with our team in Tampere to deliver an RDF production system that we are now very pleased with. It is flexible and configurable, enabling us to quickly adapt our operations to suit customers’ evolving particle size or capacity requirements, and the energy efficiencies we have witnessed, make the XR a very financially and environmentally sound investment. I wouldn’t hesitate to recommend this technology to other waste management firms worldwide.”

"Now that our new SRF plant is up and running, with state-of-the-art configurable technology in place, the next step is to investigate relationships with different customers. We can satisfy varied specifications, and look forward to improving South Korea’s resource agenda."
Adjustable main cutting bar
The adjustable main cutting bar offers you the option to adjust the cutting opening. The shredder can be optimally adjusted for the material to be shredded and the required discharge fraction.
This option is only available for the "cutter system"..
We don't let anything burn. In terms of fire protection and fire-extinguishing systems, we rely on the expertise of leading providers of fire-extinguishing systems. A camera monitors the discharge conveyor belt and is able to activate the fire-extinguishing system within milliseconds in the event of spark formation.
A service platform provides you with an easy, secure and ergonomic access to the machine in the event of servicing or maintenance.
Control cabinet room
We recommend that our customers use a control room to protect the electric control. Thanks to the positive pressure, the electric control cabinet and the frequency transformer are protected against dirt and dust, which increases their service life and minimizes their vulnerability.
We offer different hopper shapes that are exactly adapted to your infeed type. Regardless of whether you need a hopper for a wheel bearing infeed or a hopper with a grabber infeed – we will always have a suitable solution available.
In terms of separating metallic iron-containing parts from the shredded material we collaborate with leading manufacturers in the separation technology field. The overbelt magnet is installed above the discharge conveyor belt and reliably separates the iron-containing parts from the output material.
We offer suitable infeed, discharge and incline conveyor belts for our shredding machines, thereby ensuring smooth material transport.
