Title:
被覆銅線処理方法
Document Type and Number:
Japanese Patent JP4008331
Kind Code:
B2
Abstract:
A shredder dust electrostatic separation apparatus separates and recovers various kinds of crushed pieces included in shredder dust by the use of electrostatic force. The apparatus includes a rotating drum (2) made of a conductive material, which receives supplied shredder dust, a positive or negative voltage being applied thereon. The apparatus further includes a discharge wire (15) strung along the sideline of the rotating drum (2). A negative or positive voltage is applied to the discharge wire (15) to cause a discharge in a space between the discharge wire and the rotating drum. The various kinds of crushed pieces included in the shredder dust are charged by the discharge, the polarity of the crushed pieces being opposite to that of the rotating drum. The charged crushed pieces are attracted to the rotating drum. The charges of the crushed pieces are allowed to move to the rotating drum in accordance with the conductivities of the crushed pieces. Accordingly, there are differences in attraction force of the crushed pieces. The crushed pieces are appropriately separated and recovered based on such differences in attraction force.
