Winco Plastics, a US full service recycling company, has installed a compact regrinding line developed by Austrian Lindner-Recyclingtech GmbH in a bid to increase plastics waste handling capacity.
In a 26 June statement, Lindner said the “tailor-made” line includes a Micromat 2500 pre-shredding system and a grinder, with which Winco has “significantly increased” its output.
The range of rigid materials fed into their Lindner system includes HDPE pipes of any size and thickness, HDPE sheets, PE and PP purge, and PC sheet as well as PET, mainly from post-industrial sources such as automotive and others.
The new line has an output of 4,000 to 6,000 pounds of ½” regrind material per hour.
According to Tim Martin, president of the North Aurora, Illinois-based Winco, the decision to purchase Lindner's regrinding line was its ability to handle the wide variety of size, weight and form.
“We were happy to see that Lindner's regrind line is designed to shred heavy parts, including pipes up to 8' long, purges and logs up to Gaylord size as well as light material which can be directly ground,” he added.
The Micromat 2500 shredder, supplied for the line, is a high-performance single-shaft shredder equipped with a customised internal ram enabling high throughput materials.
The pre-shredded material is then discharged for direct feed into the downstream grinder.
The line, with its compact design, has been installed on 1200 sq. feet, explained Christopher Howard, general manager of Lindner-Recyclingtech America LLC.
According to Howard, the system is “very sensitive” to any contamination and is equipped with dual protection technology – a safety clutch on the Micromat 2500 shredder and a metal detector installed on the feeding conveyor into the grinder.
Additionally, the rotor is protected by a hard coat to extend lifetime when shredding abrasive material, Howard added.
