Recycling equipment separates functions

K 2004 was the launch site for recycling equipment supplier Erema's patented Double Disc Technology (T-DD), in which two disks are employed in the cutter/compactor in separate chambers. This advancement results in the separation of the shredding, mixing, drying, and prehomogenizing steps (chamber one) from the extruder feeding step (chamber two). In the past, both processing stages were integrated in a single step using one disk.

The new technology reportedly enables very uniform extruder operation, even for large feed sizes. Moreover, processing of materials with considerably higher moisture contents compared with single-disk cutter/compactors is also possible. Furthermore, capacity is up to 15% greater on average (with no change in plant size), with up to 30% reduction in specific energy consumption. The system on show at K 2004 in Dusseldorf, Germany had a processing capacity of 1000 to 1200 kg/hr.

The new system also enables reduced melt temperature, and in some cases, it is possible to retrofit the DD package to existing Erema plants. Erema, Linz, Austria; www.erema.at
