ているものである。Accordingly, in the present invention, in an apparatus for dispersing light raw materials from a mixture of light raw materials and heavy raw materials, a supply cylinder for supplying the mixture is suspended in the upper center corresponding to the hollow part of the vertical hollow cylindrical separation chamber. In the center of the bottom, a wind-selected residue removal cylinder is arranged vertically, and a tapered surface is formed at the bottom of the supply cylinder so that the shape of the supply cylinder forms the separation area, acceleration area, and fall area from above into the separation chamber. Solohan ball-shaped bulges are provided at the top and bottom of the separation chamber so that the cross-sectional area of the acceleration region is narrower than that of the separation region. A ventilation member for uniform air blowing is provided at the bottom so as to surround the periphery of the wind separation residue removal cylinder, and the air sent upward into the separation chamber through the ventilation member is sent from the supply cylinder and distributed in a circle by the distribution plate. Among the raw materials distributed in the circumferential direction, the lighter ones are raised and the heavier ones are allowed to fall.In the middle of the separation area, the heavy raw materials that have risen due to the accelerated wind speed in the acceleration area are gradually decelerated by the influence of gravity. A plurality of secondary air intakes are arranged below the separation area on the separation chamber surrounding wall, and the secondary air is decelerated in the separation area and falls down. The basic idea is that the light materials entrained in the heavy materials are returned to the separation area and screened again.
