WITH the installation of two new VEGA L 1100 single-shaft shredders from Lindner reSource, Lohner Kunststoffrecycling GmbH of Vechta, Germany has vastly improved its energy efficiency in recycling engineering polymers.

“By opting for the VEGA L 1100, we have been able to reduce the connected loads of our single-shaft shredders by 50%, at unchanged throughput. This is in addition to significant cost savings achieved in pre-shredding production waste, not least through a significant cut in wear costs,” said Jan-Hendrik Wilming, LKR’s managing director.

Based on previous encouraging experience with Lindner’s recycling technology, LKR is now installing an additional Micromat Plus 2000 single-shaft shredder as part of its current capacity expansion drive. Machines from this series are capable of handling particularly large and heavy plastic waste at high volume rates. This investment too was made with low energy consumption and high productivity consistently in mind.

VEGA single-shaft shredders made by Lindner reSource deliver throughputs of between 300 and 1500 kg per hour, depending on configuration and equipment level. Users can choose between two rotor diameters (282 and 434 mm), three rotor lengths (540, 1 080 and 1 620 mm), and two blade types (point blade or square blade rotor).

The VEGA L 1100 in use at LKR have been developed for shredding hard plastics at low rotational speeds. Due to the special blade arrangement on the rotor, only one blade is engaged at any given time. This design ensures a controlled draw-in action, reduced noise emissions, and a lower rate of fines in the pellet output. Beyond this, the machine features easy access for screen changes and maintenance work or repairs, to comply with high quality standards. 

With their throughput capacity of 500 to 800 kg/h, these units are particularly well suited for pre-shredding small-to-medium size batches, e.g., in the form of start-up lumps, larger automotive plastic parts, packaging items or sheet material. Their ability to process the entire range of engineering plastics, including tough or exceptionally hard products such as PE, PC or POM, gives recyclers maximum flexibility.

The substantially larger Micromat Plus single-shaft shredders, delivering nominal throughputs of up to 5 000 kg/h, are intended for industrial-scale plastics recycling. Their rotor measures 563 mm in diameter, and the customer has a choice between rotor lengths of 1 530 mm, 2 030 mm and 2 350 mm. Three different drive systems are available to meet specific application needs. Versatility is further enhanced by the easily replaceable screens with 10 to 300 mm hole diameters. LKR employs the new Micromat Plus 2000 as a pre-shredder for large mono-batches. Apart from large-volume parts and heavy lumps, even contaminated plastics can be processed in this manner.
