Single-pass shred for SRF

Untha has received interest in its XR-C waste shredder from alter­native fuel producers across the world. It is working on more than 250 global prospects, and has already secured European orders worth e5m (£3.6m) in the past six months, with clients including Sita and Switzerland-based Holcim.

According to Untha, the XR Cutter can produce a high-quality solid recovered fuel (SRF) in a single pass, with double the out­put per tonnage of competing machines. Bulky untreated waste can be fed into the machine and, when comparing like-for-like tonnages, the XR uses 50% less power than competitors’ static electro-hydraulic shredders.

Peter Streinik, head of shred­ding solutions for waste, said: “The beauty of the XR machine is its flexibility. The cutting concept is completely configurable, enabling alternative fuel producers to manufacture a refuse-derived fuel with a homogenous predetermined particle size of 100- 400mm or a precise SRF with a 30mm fraction or less.”

Load-dependent speed controls enable the XR’s RPM and torque to be adjusted and optimised in order to achieve throughputs of up to 70 tonnes/hour.

The machine features a high torque, slow speed ‘Eco Drive’ con­cept. It has modern water-cooled synchronous motors which work continuously without overheating. This keeps running and mainte­nance charges minimal, with typ­ical wear costs significantly less than e1 per tonne.

The shredder can be serviced and maintained quickly and safely in an upright position. It runs at below 70dB(A) when empty and less than 80dB(A) during processing operations.
