the recycling of big bags and carpets are a challenge that all
shredder manufacturers
are well aware of,” says Mårtensson. “The material tends to wrap around the rotor which creates lots of problems. Rapid has now developed a new rotor design that solves the wrapping problem. The first units are already installed in the market with good results. In

addition, the new extended pusher system will be able to accommodate large plastic pallets and bales of scrap. With the enlarged inlet we can increase the number of applications for the Raptor series in line with the demand that we see from our customers.” In addition, Rapid offers the Duo Concept, which also incorporates a granulator in the design. The company says that the one-stage process has a small footprint and low installed power, and can produce granules direct from the machine, which has proved to be a popular solution. Even with a built-in grinder Rapid says that it has been able to provide good access to the internal parts for cleaning. Lindner has introduced the Micromat 1500
shredder to its existing range, offering a new and improved universal cutting system. The Micromat 1500 – rotor length of 1,500mm – is a new entry- level model which includes the Multiplex cutting system. The company says that due to the three- dimensional arrangement of the rotor knives, the system can shred almost any plastic. As a result of the knives actively pulling in the material, output can realistically be increased by around 40% on average compared to previous technologies. “During development, we tested a wide range of
materials together with our clients and optimised this cutting system’s geometry to cover as many types of plastic as possible,” says Stefan Scheiflinger- Ehrenwert, Head of Product Management. “The long-term test finally revealed that the new Multi- plex rotor not only increases the throughput enormously, but in some cases even multiplies it.” In addition to mechanical improvements, the
machine’s software and controls have been redeveloped. With the new Lindner Mobile HMI, the manufacturer is reacting to the growing shortage of skilled workers and focusing on simple, self-explanatory menu navigation. The mobile control panel can be placed at the front or rear of

the shredder depending on the task at hand, for example a screen exchange. Moreover, 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 material’s quality to the extruder. Lindner has also launched the Micromat HP
series, a shredder that is specially designed for shredding post-consumer and post-industrial film. Equipped with a direct belt drive that enables rotor speeds of over 300 rpm, the machines can pro- duce 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 unnec- essary, meaning that energy and maintenance expenditure is significantly reduced while simulta- neously lowering investment costs. Lindner has also recently supplied Lohner
Kunststoffrecycling (LKR) with a new cutting system to increase capacity. LKR is based in Vechta, Germany and has been recovering plastics waste generated in the production of industrial and consumer goods since 1992. The company is now part of the Remondis Group and processes around 45,000 tonnes of rejects into new material every year. LKR uses Lindner’s Micromat 2000, which is equipped with the Multiplex cutting system. The machine efficiently shreds almost any type of plastic. Productivity gains, even for difficult materi-
