用于对重质的塑料富集的分化物进行处理的方法和设备
Abstract:
本发明涉及用于处理重质的塑料富集的分化物(SF)的方法和设备，在处理金属贫乏的塑料富集的至少部分地来自旧车辆的破碎过程的废物(KA)时得到所述分化物。按本发明的方法至少具有以下先后相随的方法步骤：将金属部分(FE、NES、NE)从重质的塑料富集的分化物(SF)中分离出来(VG1、VG2)；将在分离出金属部分之后剩余的金属减少的重质的塑料富集的分化物(KFA)粉碎(VG4)；将在分离出金属部分之后剩余的金属减少的重质的塑料富集的分化物(KFA)分化(VG6)为不同粒度的塑料富集的分化物(KF1到KF3)；至少部分地在分开的过程中对所分离的塑料富集的分化物(KF1到KF3)进行处理(VG8-VG13)。按本发明的设备包括用于实施所述方法步骤的相应的器件。借助于本发明来获得高纯度的可以输送给材料的回收利用系统的粒料分化物。
Abstract(English):

The invention relates to a method and a system for preparing a heavy plastic-rich fraction (SF) obtained by preparing low-metal, plastic-rich waste (KA) originating at least in part from shredder processes of scrap vehicles. The method according to the invention comprises at least the following successive process steps: separating (VG1, VG2) metal parts (FE, NES, NE) from the heavy, plastic-rich fraction (SF); shredding (VG4) the heavy, plastic-rich, metal-reduced fraction (KFA) remaining after separating the metal parts; dividing (VG6) the heavy, plastic-rich, metal-reduced fraction (KFA) remaining after separating the metal parts into plastic-rich fractions (KF1 to KF3) of different grain sizes; preparing (VG8-VG13) the separated plastic-rich fractions (KF1 to KF3) at least partially in separate processes. The system according to the invention comprises appropriate means for performing the process steps. Using the invention, a highly pure granulate fraction is obtained and can be fed into a material recovery system.
