Waste Recycling – Recovery of Substitute Fuels
In the recycling of waste for the recovery of substitute fuels, the focus is on utilizing waste as a valuable raw material that can be further processed to create economic and ecological value. At the same time, this process contributes significantly to resource conservation and sustainability.
A central aspect is the targeted recovery of the intermediate fraction as the target product. This defined fraction represents the actual usable fuel. The coarse material is returned to the crusher or shredder to be reprocessed and achieve an optimal grain size.
Fine components, on the other hand, must be consistently separated. These often consist of mineral components that can lead to slagging in the combustion process, as well as very fine particles that cause unnecessarily high ash formation and negatively affect the combustion process.
For even more efficient processing, the use of ripping blades can be beneficial to reliably open garbage bags during the screening process and improve material release.
Additionally, magnetic separators can be installed on all discharge belts to separately recover metals.
