High efficiency low-speed shredder for production of alternative fuels
The XR class is a high-performance waste shredder that can serve as primary shredder or single-step shredder in the production of alternative fuels. It is both low maintenance and easy to maintain with a long service life. Smooth system operation is ensured with replacement parts and optional remote troubleshooting!
The XR class is a very energy-efficient low-speed, single-shaft shredder that was specifically designed for shredding coarse and medium-sized untreated household (MSW), industrial and commercial waste (C&I) as well as for recycling scrap wood. It can be used as a pre-shredder in a comprehensive system or simply as a single-phase shredder.
Thanks to XR’s low and class leading operating performance, the new waste shredder particularly stands out. The revolutionary UNTHA Eco Drive concept ensures up to 50% less energy consumption compared to typical electro-hydraulic drive options.
The cutting-edge synchronous motors provide maximum efficiency, making the UNTHA Eco Drive one of the most energy efficient drive systems on the market. In addition, maintenance costs are minimized as couplings, belts, hydraulic pumps and shafts stubs are no longer required.
In order to meet your requirements, the XR primary shredder can be equipped with a ripper or a cutter system. In combined with the patented XR screen bar system or with different perforated screens, a controlled fraction size of 400 to 30 mm is guaranteed. Depending on the material property and screen size chosen, throughput performance is between 10 t/h and 70 t/h.
The rotors are protected against wear by welded-on Hardox plates and are particularly resistant to abrasive materials.
Our experienced project engineers will be happy to help you choose the best shredder for your project.
XR class applications:
- Commercial and industrial waste (C&I)
- Household waste (MSW)
- Wood waste
- Scrap wood
- Compressed plastic bales
- and many more
More details about the primary shredder is available below in the downloads section
"Cutter" cutting system
The "Cutter" cutting concept is a "cutting system" for material sizes ranging from 120 mm to 30 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.
"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.

“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.”
Reference: Zion Waste Management Ms. Geumju Kim (President)
"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. UNTHA offers fire protection systems from leading manufacturers to protect your investment. Optical monitoring of the shredder discharge can activate the fire extinguishing system within milliseconds of its first detecting a spark.
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.
