The new Atlas shredder from Lindner
E-drive and intelligent energy management – an innovative yet ingeniously simple solution
Lindner is responding to the increasing demands placed on the automated sorting of valuable recyclables as well as the ensuing rise in the need among producers of solid recovered fuels (SRF) for pre-shredded yet ideally sortable material. With the new Atlas, the leader in shredding technology is not only focusing on the energy efficiency of shredding systems, but also on the ideal output size with continuous dosing for optical sorting systems and a maximally possible resistance to foreign parts at the same time.
Uniform material discharge, more recyclables
Designed for very high uptimes (24 hours a day, seven days a week), the ‘ripping twin-shaft shredder’ has a throughput capacity for coarser output sizes and uniform material discharge of 40 to 50 metric tonnes per hour, depending on the feed material. As a result, more recyclable materials, in particular plastics such as film from mixed municipal solid waste as well as from commercial and industry waste, can be collected for recycling. In addition, it is possible to meet ambitious quotas and guidelines. The shredder supplies the downstream sorting system with a perfectly dosed and uniform output – the perfect prerequisite to ensure maximum efficiency of the sorting facility (e.g. NIR sorting systems).
The slow-running shredder’s new asynchronously rotating shaft system ensures uniform material discharge by generating high torque. In the Atlas both shafts of the robust cutting system equipped with a solid counter-cutting frame and aggressive self-intake can be rotated independently of each other. If one of the two shafts comes to a standstill due to non-shreddables or tough or wet and heavy feed material, the Atlas continues to shred normally in asynchronous operation with the second shaft. The shredding takes place in both directions, which explains the high throughput capacity. In fact the second shaft even unblocks the first shaft, which means that virtually no manual intervention is required.
The drive: an intelligent energy management system
The impressive throughput capacity is made possible by a special drive concept: The Atlas 5500 twin-shaft shredder is equipped with an e-drive. With a typical electric drive power of 2 x 110 kW, the shredder uses the intelligent energy management system DEX (Dynamic Energy Exchange) to always run on the optimum operating point. When reversing, the shaft changes the direction of rotation three times faster than is the case for a shredder without DEX.
In summary Lindner describes their latest innovation as an ‘intelligent yet ingeniously simple solution’. Thanks to the intelligent energy management system DEX (Dynamic Energy Exchange), the system always runs on the optimum operating point ensuring a significant increase in energy efficiency compared to conventional electric hydraulic drives.
