Wet Counter Flow Microfine Classification In A Centrifuge

This paper reports on the results of research on counter flow classification of - 10 µm particles. Two classifiers were designed and constructed, the first semicontinuous and the second fully continuous. The latest version operates continuously with recoveries of fines up to 90% at feed loads of 30 vol.%, separation sharpness X25/x75 up to 0.83, without bypass and cut sizes down to 1.4 µm (x50 from separation efficiency curve).
