Lindner Atlas Day 2019 Recap
Lindner’s Next Generation Atlas Attracted Considerable International Interest
The Austrian specialist in shredding technology and system solutions for waste processing invited guests to the Lindner Atlas Day on the scenic Lake Wörthersee on 1 October 2019 to present the eponymous next generation twin-shaft primary shredder for automated 24/7 operation.
‘At the moment, everything is heading towards a circular economy. Our diverse, international audience is proof that this trend is not only emerging in Europe, but all over the globe”, explains Stefan Scheiflinger-Ehrenwerth, Head of Product Management at Lindner Recyclingtech. These developments call for new technologies that will make it possible to cope with the ever-growing amounts of waste and to process them efficiently. To achieve this goal, Lindner’s design team focused on successfully combining the following three aspects in the Atlas shredder: ideal output size and chunkiness for subsequent sorting processes with high energy efficiency and 24/7 operation.
24/7 operation combined with minimum downtimes
New to the latest Atlas generation is the FX fast exchange system. For maintenance with minimum downtime, the entire cutting system can be completely exchanged in under an hour. Thanks to a second cutting unit, made up of a shaft pair and cutting table, it’s possible to keep up production while, for example, welding work is carried out on the rippers.
Designed with automation in mind
In waste processing, the trend is clearly towards automation. However, robots and separation technologies such as NIR sorting require uniformly flowing material – in terms of both flow rate and particle size – in order to be productive. Scheiflinger-Ehrenwerth explains: ‘Our tests have shown that materials shredded to the size of an A4 sheet and with a low fines content are ideal for preventing as many picking errors as possible in subsequent automatic sorting processes. The Atlas’ ripping cutting system is simply tailor-made for that. Even collection bags for plastic waste can be ripped open easily without shredding the contents. Due to asynchronous shaft operation, where the shafts shred effectively in both directions of rotation, we additionally achieve a constant material output of approx. 40 to 50 metric tons per hour. This means that the shredder continually delivers enough material to the conveyor belt to be perfect for productive sorting.
This fantastic performance is only possible thanks to the specifically engineered drive concept: the Atlas 5500 is equipped with a purely electromechanical belt drive. The intelligent DEX (Dynamic Energy Exchange) energy management system ensures that the system always runs at the optimum operating point and that the shafts change direction up to three times faster than in conventional drives.
