Pulverizing, separating, and size regulating molded resin articles

A pulverizing and separating process for separating and removing a resin film from a molded resin article having a resin film on its surface, thereby recovering a raw form of resin material, comprising the steps of:

• first, crushing a molded resin article into a plurality of small pieces;
• next, squeezing said plurality of small pieces by applying thereto, by means of spaced apart compression impact-applying surfaces, compression impacts based on fine vibrations;
• removing from time to time resin film coatings released by said squeezing;
• and
• supplying a separation-accelerating liquid between said spaced apart compression impact-applying surfaces.
