Classification of metals and plastics from printed circuit boards (PCB) using air classifier

摘要: With the mandatory requirement of recycling and reuse electronic scraps arising from printed circuit boards (PCB), non-polluting separation methods to separate metals plastics are growing importance nowadays. Mechanical scrap oriented towards overall materials recovery obsolete electronics is being implemented worldwide. Air classification one among clean mechanical that can achieve reasonably good PCB stuff. In present investigation, milled using a column air classifier has been studied in detail. A detailed study on species system was analysed by efficiency curve approach model parameters such as reduced parameter (α), corrected cut size (Va/Vt)50c selectivity increment (ΔS) with respect process variables. The relationship for all experimental data were (α). accuracy developed checked predicted values observed values. results showed simulation able predict satisfactorily.
