21.10.2019 Shredding and recycling of plastic waste

Lindner-Recyclingtech, Spittal an der Drau, Austria, at K2019 demonstrated a working model of its new Micromat 1500 plastics shredding machine and also exhibited a new and improved universal cutting system. Based on Lindner’s tried-and-tested technology, the Micromat series has been further optimised to meet current market demands in the plastics industry. With the 1500 size – signifying a rotor length of 1500mm – a new entry-level model from the Micromat series has been created. The most innovative feature is the new Multiplex cutting system. Thanks to the three-dimensional arrangement of the rotor knives, this advanced system can shred almost any plastic. As a result of the knives actively pulling in the material, output can realistically be increased by some 40% on average compared to previous technologies.

In addition to mechanical improvements, the machine’s software and controls have been redeveloped from scratch. By offering the new Lindner mobile HMI (human/machine interface), the company is reacting to the growing shortage of skilled workers and focusing on extremely simple, self-explanatory menu navigation. The touchscreen only displays the relevant functions. With the new control software, the shredder is able to communicate with downstream equipment in the process chain and, for example, function as a dosing unit for the facility or pass on data about the materials’ quality to the extruder.

With the Micromat HP series, Lindner has launching a shredder that is specially designed for processing post-consumer and industrial film. Equipped with a direct belt drive that enables rotor speeds of over 300rev/min, these new machines can produce up to 2.5 times more output than the basic version in this area of application.

Furthermore, the new cutting system is able to precisely cut plastics into flakes for cleaning, sorting and subsequent extrusion in just a single step. The advantage of this feature is that additional fine granulation is unnecessary, meaning that energy and maintenance expenditure is significantly reduced while simultaneously lowering investment costs.
