Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a frictional charging apparatus whereby chargeable plastic particles as an objective to be separated can be continuously and efficiently subjected to frictional charging. SOLUTION: A plastic particle mixture containing plastic particles as the objective to be separated and friction assisting particles are agitated in the agitation container 31 of a mixer 3 to frictionally charge the above particles. The friction assisting particles are separated from the plastic particle mixture by means of a classifier 4. The friction assisting particles reduced in a charge quantity by spontaneous discharging or still more reduced in a charge quantity optionally by static eliminator 64 are fed into the container 31 and are repeatedly used.
