Title:
ELECTROSTATIC SELECTOR
Document Type and Number:
Japanese Patent JP3308429
Kind Code:
B
Abstract:
PURPOSE: To improve the classifying accuracy by strong attraction force and to prevent the flying of a material to be classified caused by an ionic wind.
CONSTITUTION: An electrode forming an electric field between it and a conductive rotor is integrally constituted of a planar electrode part 22A forming an electrostatic area D1 and an acicular electrode part 22B forming a corona discharge area D2. In this way, an ionic wind to the upstream side is eliminated by the planar electrode part, and strong attraction force is given to insulating crushed refuse by the acicular electrode part.
