Lindner-Recyclingtech makes key new product announcements at IFAT 2018
Lindner-Recyclingtech GmbH made several key new product introductions at this year's IFAT, held in May, in Munich, Germany, including the Polaris 1800 model, a specialized shredder designed for SRF (solid recovered fuel) applications, the Zeta Star 95 F2 starscreen for processing waste wood fuel, and the Atlas 5500, a new twin-shaft primary shredder with an innovative electric drive.
Polaris - One-step shredding
The new Polaris 1800 model (shown above) showcased at IFAT 2018, was developed for the one-step production of medium-calorific solid recovered fuel (SRF) which is used for incineration in calciners. The Lindner Polaris shreds municipal solid, commercial and industrial waste to defined final output sizes in one step.
"We have succeeded in establishing the Polaris as a synonym for one-step, cost-efficient SRF processing in the industry," said product manager Stefan Scheiflinger-Ehrenwerth. "As a leading supplier, Lindner provides the solution for feed materials that contain foreign objects, or are wet and heavy, bulky or generally difficult - as often encountered by waste management companies."
The Polaris 1800 model, a smaller model in the Polaris series, is aimed at companies that still have capacities for material processing and want to enter the market for medium-calorific SRF. The Polaris 1800 is also ideal for those companies in regions that do not have extreme amounts that need to be processed. "Furthermore, the Polaris 1800 also has enormous potential for use in emerging markets that are only just beginning to process waste. Since structures have to be built up there first, this solution is the ideal entry model," said Scheiflinger-Ehrenwerth.
The Lindner Polaris 1800 has an output rate of up to 16 metric tons per hour and shreds almost any feed material, in particular, industrial, commercial and municipal solid waste. Polaris users love the machine's enormous power thanks to the countershaft drive, flywheel mass effect, optimised material feeding (internal pusher for increased volumes and easy feeding), the hydraulic maintenance door (for fast removal of foreign objects and convenient rotor maintenance) and last but not least the robustness and durability of the cutting system's cutters. The Polaris series also sports a newly developed cutting system and is - compared to all other single-shaft shredders - the most efficient in terms of costs per ton. The countershaft drive functions like a large flywheel mass acting like a battery. If the Polaris is not fully utilised during operation, the mass charges itself and can therefore absorb load peaks if necessary. This stored energy allows for continuous shredding and ensures the highest throughput rates even with difficult materials.
Atlas - Primary shredding with intelligent energy management
At IFAT 2018, Lindner introduced the Lindner Atlas. This stationary ‘ripping' twin-shaft primary shredder perfectly complements the tried-and-tested Jupiter series: the newly developed ripping system ensures very high throughputs and little downtime: it is (cost)-efficient, energy saving, environmentally friendly and produces little noise.
Optical sorting systems, such as those following primary shredders in modern SRF lines, can sort out recyclables more effectively and thus better comply with legal regulations and requirements if the discharge conveyor is evenly filled with material. Furthermore, coarser particles are often an advantage. Film, for example, should be the size of an A4 sheet.
In response to greater demands on recycling sorting processes and the growing need for coarser output in SRF production, Linder has developed the Atlas: the ideal primary shredder complemented by the outstanding secondary shredders in the Komet series.
