Austria: UNTHA Shredding Technology has launched its new XR ripper and cutter series of pre shredders for the production of refuse derived fuel (RDF) and solid recovered fuel (SRF).

The new XR shredders offer flexibility to the final particle size by the use of two distinct cutting methods that can be configured and re-configured by the end user. The tearing motion achieves a rough shred of untreated waste, with a homogenous, pre-determined particle size between 100 - 400mm, while the final fraction size is regulated by adjustable screen bars. Load-dependent speed controls adjust the XR shredder's RPM and torque to maximise throughputs of up to70t/hr.

Key benefits of the XR shredder include:

• 45 - 50% less energy consumption, which can equate to over Euro631,066 in electricity savings over the lifetime of the machine,

• Load-dependent speed controls which adjust the RPM and torque to achieve maximum throughput of up to 70t/hr,

• Synchronous, water-cooled motors work tirelessly without overheating, guaranteeing the XR's unparalleled uptime statistics,

• Consistent particle sizes between 50mm - 400mm achievable, depending on requirements,

• Less than 75dB of noise output.
