| Research Abstract |
In recycling plant of the covered cable, the cable was crushed into two materials, Cu and PVC. The wind-force has been used to separate two particles according to the difference of specific gravity. If Acoustic emission (AE) sensor is installed in the air classifier, it is possible to monitor the collision noise of the particles. This study purpose is to measure an impact sound of the particles, and to construct the system to identify Cu or PVC. In this study, the criterion power spectra were employed to discriminate unknown particles. Furthermore, we had controlled the airflow rate before controlling the yield. It presents a comparison of the performances of the generalized minimum variance control with that of conventional proportional and integral control.
