SAMPLING METHOD AND SAMPLING DEVICE OF RECYCLED RAW MATERIAL, ANALYSIS SAMPLE OF RECYCLED RAW MATERIAL, AND EVALUATION METHOD OF RECYCLED RAW MATERIAL

摘要

Provided is a sampling method of recycled raw material, the method including:aprocess (S3) of primarily crushing recycled raw material; a process (S4 to S7)ofseparating primarily crushed raw material into three components, "scrap iron","scrapaluminum", and "recycled raw material component other than scrap iron andscrapaluminum" and performing primary sample reductions of the three components; aprocess (S8 to S10) of secondarily crushing "the recycled raw materialcomponent otherthan scrap iron and scrap aluminum", which is subjected to the primary samplereduction,and performing a secondary sample reduction of "recycled raw materialcomponent otherthan scrap iron and scrap aluminum" which is secondarily crushed; a mixingprocess(S12) of mixing "scrap iron" and "scrap aluminum" with "the recycled rawmaterialcomponent other than scrap iron and scrap aluminum" which is subjected to thesecondary sample reduction at a mixing ratio corresponding to a weight ratioof "scrapiron", "scrap aluminum", and "the recycled raw material component other thanscrap ironand scrap aluminum", in which a mixture obtained in the mixing process is setas ananalysis sample.
