METHOD AND DEVICE FOR SAMPLING RECYCLE RAW MATERIAL, AND SAMPLE FOR ANALYZING RECYCLE RAW MATERIAL

摘要

PROBLEM TO BE SOLVED: To collect a uniform sample for evaluation.SOLUTION: The method for sampling a recycle raw material includes: a primarily crushing step (S3) of crushing a recycle raw material; primarily reducing steps (S4 to S7) of classifying the recycle raw material after the primary crushing into three kinds of "Fe waste", "AI waste", and "recycle raw material other than Fe waste and AI waste"; secondary crushing and reducing steps (S8 to S10) of secondary crushing and reducing the "recycle raw material other than Fe waste and AI waste" after the primary reducing; and a mixing step (S12) of mixing "Fe waste" and "AI waste" into "recycle raw material other than Fe waste and AI waste" after secondary reducing at mixture ratio corresponding to weight ratio of the three kinds of "Fe waste", "AI waste", and "recycle raw material other than Fe waste and AI waste". The wastes mixed in the mixing step are defined as samples for analysis.
