Waste Shredder Improves SRF Production
The new UNTHA XR-C waste shredder produces a high-quality solid recovered fuel (SRF) in a single pass, with double the output per tonnage of traditional machines; it also uses 50% less power consumption than traditional static electro-hydraulic shredders, the company says.
Swiss-based Holcim and SITA are the most recent clients to invest in the machine. UNTHA says it is currently working on proposals for more than 250 other global prospects.
The machine works with a high-torque, slow-speed “eco-drive” concept. Modern water-cooled synchronous motors work continuously without overheating, ensuring minimal disruption and highly sought-after uptime. This also keeps ongoing running and maintenance charges minimal, with typical wear costs significantly less than €1 per tonne, according to the company. The XR machine is completely configurable, enabling alternative fuel producers to manufacture an RDF with a homogenous pre-determined particle size of 100-400mm, or a precise SRF with a 30mm fraction or less. Load-dependents speed controls also enable the XR’s RPM and torque to be adjusted and optimized, in order to achieve throughputs of up to 70 tonnes per hour.
