Austria: UNTHA Shredding Technology is currently working on proposals for more than 250 global prospects, eager to reap the benefits of its innovative new XR-C waste shredder. European orders in the last six months stand at Euro5m, with Holcim and SITA the most recent clients to invest in the machine.
The robust XR Cutter is able to produce high-quality solid recovered fuel (SRF) in a single pass, with double the output per tonnage of competing machines. Input material can include bulky untreated waste. When comparing like-for-like tonnages, the XR uses 50% less power consumption than traditional static electro-hydraulic shredders.
The power savings are due to UNTHA's new high-torque, slow-speed 'Eco Drive' concept. Modern water-cooled synchronous motors work continuously without overheating, ensuring minimal disruption and downtime. This also keeps running and maintenance charges minimal, with typical wear costs significantly less than Euro1/t.
"The beauty of the XR machine is its flexibility," said Peter Streinik, UNTHA's head of shredding solutions for waste. "The cutting concept is completely configurable, enabling alternative fuel producers to manufacture SRF with a homogenous pre-determined particle size of 100 - 400mm, or a precise SRF with a 30mm fraction or less. Load-dependent speed controls also enable the XR's RPM and torque to be adjusted and optimised, in order to achieve throughputs of up to 70t/hr."
