To obtain a function of flexibly adjusting an electrified state of a plastic particle-mixed raw material according to a change of the kind or composition of the plastic particle-mixed raw material and a method for electrifying the plastic particle-mixed raw material continuously and stably while restraining the accumulation with time of an electric charge on an auxiliary electrifying material.
An electrostatic sorting apparatus 1 of one embodiment is provided with: a raw material feeder 2 for supplying the plastic particle-mixed raw material; an ion feeder 3 for supplying an ion or the electric charge; a triboelectrifier 4 for triboelectrifying the plastic particle-mixed raw material to be supplied from the raw material feeder 2 together with the ion or electric charge to be supplied from the ion feeder 3; and an electrostatic separator 5 for sorting the mixed raw material triboelectrified by the triboelectrifier 4 by an electrostatic sorting method.
