Title:
ELECTROSTATIC SORTER OF RESIN AND METHOD THEREOF
Document Type and Number:
Japanese Patent JP2014168754
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve the problem of reducing the recovery ratio or reducing purity of a recovery resin, by overlapping the charge quantity distribution of a different resin, in an electrostatic sorter for separating-recovering by an electrostatic field, by frictionally electrifying a plurality of kinds of resins.SOLUTION: When separating three kinds or more of resins, an intermediate charge quantity can be approached to zero by increasing a quantity of resin kinds of indicating the intermediate charge quantity, and the recovery ratio or the purity of the resin is improved by separating from the charge quantity distribution of the other resin. In the electrostatic sorter for separating-recovering by the electrostatic field, the recovery ratio or the recovery resin purity is improved by expanding a charge quantity difference between the resins by approaching the charge quantity of its resin to zero, by increasing the quantity of resin whose charge quantity indicates the middle in the resin kinds.
