Size reduction in waste resources has increased considerably due not just to the need for smaller volumes but as well as the need for secondary recycleables and the effective use of waste materials as a fuel source. Refuse Derived Fuel could be produced from industrial sources of waste, household consumer waste, or also from sources such as paper, carpet, and wood fiber materials.
Pre-shredders play an important role in the area of waste-to-energy equipment. Pre-shredding is the initial step in the process of shredding unclean and bulky materials. From this point, materials are then processed or sorted utilizing separators, magnetic systems, or screens prior to being sent for further size reduction and shredding to be used as a alternative or substitute fuel resource.
