This electrostatic separator leverages the disparity in mineral conductivity and the influence of electric fields to facilitate mineral sorting. By exploiting these fundamental differences, the machine effectively separates conductive from non-conductive minerals, generating high-purity concentrates of both types, such as rutile and zircon.
Compatible with single-disc, double-disc, permanent magnet, and electromagnetic systems, this versatile equipment extends its applicability beyond standard mineral separation. The separator’s ability to process high-phosphorus ore and refractory rutile is enhanced by its integrated 0-45,000 volt high-voltage generator.
Working Principle of Arc Plate Electric Separator
The arc plate electric separator employs a two-row, four-floor structure equipped with stainless steel grounding arc slides on each level. A high-voltage, adjustable aluminum arc plate is positioned at the top. The separation process leverages a composite electric field, combining corona and electrostatic fields, to differentiate materials based on conductivity. Conductive materials experience enhanced electrostatic attraction, while non-conductive materials encounter increased repulsion.
As the material mixture undergoes crushing and grinding, it enters the cylindrical separator through a feed funnel. The rotating cylinder exposes the material to the corona electric field generated between the high-voltage and grounding electrodes. Conductive particles, upon contact with the grounding electrode, acquire a charge and are subsequently ejected into the conductor particle receiving groove due to centrifugal and gravitational forces.
Non-conductive or weakly conductive particles exhibit difficulty transferring charges upon contact with the cylinder. These particles accumulate charges and adhere to the cylinder’s surface before being dislodged into the non-conductive particle receiving groove by the rotating brush.
