Shredder upgrade saves energy, improves throughput

More throughput while using less energy is a pretty good tradeoff, and that exchange is said to be realized as the result of recent upgrades to the established Vega-brand shredders from manufacturer Lindner reSource GmbH. Even at a modest speed of up to 250 revolutions/minute, the company's newly developed Super-Vega model can reduce plastics scrap to pellets sized 10-15 mm.

As a result, claims the manufacturer, processors can forego using a conventional cutting mill, get pellets sized as they want, and still realize the benefits of a single-shaft shredder, such as large feeding hoppers, start-up under load, and low costs for wear and tear. The upgraded machines are said to be especially well suited for the shredding of difficult materials such as big bags, filaments or films.

The company, based in Grossbottwar, Germany, says the Vega S (Super) 1100 single-shaft shredder can achieve a throughput capacity of 500-800 kg/hr with a drive power of only 22 kW, an output/energy use ratio it says can be realized largely as a result of development of its square-blade rotor. —mpweditorial@cancom.com
