Title:
METHOD AND DEVICE FOR SEPARATING GRANULAR SUBSTANCE
Document Type and Number:
Japanese Patent JPS59109260
Kind Code:
A
Abstract:
Particles having different properties (e.g. particulate fly ash and carbon) are separated by moving the particles forwards along a horizontal electrode plate (1) above which is mounted a second electrode (2) having two plates (4) each extending sideways from a central block (3) of dielectric material at an acute angle (a) to the horizontal. An alternating electric field is generated between the electrodes (1, 2) by a high voltage AC power source (14). The field lines (16) from each plate curve to the side and impart centrifugal forces to particles charged by friction or conductive induction, which forces separate lighter, more highly charged particles from the others. The separated particles are collected in bins (13) arranged around the lower electrode (1), which electrode is mounted on a vibratory transducer (12).
