文摘

•: Waste PCB metal and nonmetallic powders are separated by air separation.
•: A conformational mechanism of PCB particle air separation is proposed.
•: Metal grade and yield formula in air separation is deduced.
•: Particle shape factor and airflow velocity distribution are considered.
•: Experiments show that the formula can provide an engineering guide to design and operation.
