Shredding giant Untha has launched its 3rd series XR waste shredder. While the machine has the same sleek construction as its predecessors, its internal workings have been refined so it can handle a wider range of input materials and achieve improved performance figures.
Different cutter configurations, torque settings and motor modifications mean that one day the shredder can be producing a P63-specification biomass fuel with low fines output from waste wood, for example. The next day it could be manufacturing a high-quality solid recovered fuel with homogenous <30mm particle sizing, before going on to achieve a 75mm gasifier material – all in a single pass.
Untha’s head of the waste shredding division, Peter Streinik, said: “This 3rd series machine has been three years in the making and €1m (£850,000) to perfect.
“It can tackle everything from ordinary commercial waste through to incredibly complex applications such as pulper ropes. We have designed the machine so that it achieves the throughputs achieved by a higher speed shredder, with far lower wear rates, operating costs and energy consumption.
“The build and rigidity of the kit, along with its in-built protection from ‘unshreddables’, has opened up new opportunities. We are even configuring one machine that gives excellent recovery rates when using optical sorting equipment within a MRF or fuel preparation line – this would have previously only been possible using two-shaft technology.”
