AI Technical Summary

Technical Problem

Existing methods for separating metal and resin materials from resin-plated parts suffer from low separation efficiency due to variations in particle size and the angle of repose, leading to mixed recovery of metal and resin materials in the wrong tanks.

Method used

A method and apparatus that involves crushing the metal-coated resin material into a mixed powder, conveying it on an inclined belt, and using magnetic forces and adjustable magnet strengths to separate metal-coated resin powder from resin powder in multiple stages, with optional vibration and air injection to enhance separation.

Benefits of technology

The method and apparatus achieve reliable separation of metal-coated resin materials into high-purity metal and resin raw materials by actively dropping non-magnetic components and adjusting magnet adsorption rates, thereby improving separation processing capacity and purity.

Abstract

To lower an absorption rate of resin powder with a metal film in crushed mixed powder, and separate the resin powder with the metal film from metal film powder or resin powder.SOLUTION: A separation recovery method of metal and a resin material of a metal film resin material includes: crushing a metal film resin material p to which a metal film is attached and producing mixed powder m; conveying a belt 9 where the mixed powder m is inclined and arranged while vibrating the belt 9; previously sliding down resin powder c and resin powder b' with a metal film having a low metal percentage content in a direction opposed to the conveyance direction on the belt 9 inclined in a state of exceeding a repose angle; adsorbing the metal film powder a and the resin powder b with the metal film having a high metal percentage content to a plate-like magnet 44; conveying the metal film powder a and the resin powder b in the upper direction the same as the conveyance direction of the belt 9 while being adsorbed to a roller 8 having the magnet 45, and separating and recovering metal and a resin material.SELECTED DRAWING: Figure 16
