To solve such problems, in an electrostatic sorting method, that: it is difficult to sort an insufficiently charged mixture and a recovery rate may be lowered; and even when charging is sufficiently performed, there is the possibility that sorting is not necessarily executed with high accuracy depending on a recovery method of a recovery container, etc.
The fed particle mixture of different plastics is charged by friction with rotated rotary blade 3 existing inside a charging container 2. Further, the charged particle mixture of the plastics is adsorbed to a conveyor as a recovery device existing inside the charging container 2 separately corresponding to a charged polarity (positive or negative polarity). Thus, a container is not required for recovering the uncharged particle mixture, and the particle mixture of the plastics is sorted at a high recovery rate.
