THE SEPARATION OF IRREGULARLY SHAPED FINE PARTICLES BY A VIBRATING ROTATING-DISK

A shape separator equipped with a vibrating rotating disk was develope d, and its performance was investigated for irregularly shaped particl es of 50-300 mu m in size under various operating conditions. The shap e separation was examined from the shape analysis of sorted particles and found to be effective even for 50 mu m particles, By considering f actors that obstruct the rolling motion of particles, it was confirmed that higher separation efficiencies could be obtained by minimizing t he particle adhesion to the disk, the surface roughness of the disk an d the degree of sliding or excessive bouncing of particles on the disk .
