PURPOSE: A pulverizing device for separating metal from electricity-electronic waste is provided to separate metal from electricity-electronic waste without an extra manual labor by keeping pulverized electric components in the pulverizing device for a while, which pulverizes the components elaborately. CONSTITUTION: A pulverizing device comprises: a lower part casing (10) formed with an inner space, and supporting the whole structure; an upper part casing (20) formed with a fixed space inside, and positioned on the top end of the lower part casing; a rotary blade (50) rotary-supported by the lower part casing, and rotating by the external motor; a fixed blade (60) fixed on the lower part casing separately from the rotary blade in a fixed distance; a screen (70) surrounding the lower part of the rotary blade, and forming a stay space between the rotary blade; multiple through-holes (71) formed on the screen; an inlet (30) for putting products to the top end of the upper part casing; and an outlet (40) formed on the bottom end of the lower part casing, and discharging the pulverized products.
