Abrégé

An air-pressure-type dual-bin air-powered separator. An upper side wall of a separation bin (11) is in communication with an upper side wall of a material drop bin (12); a conveyor mesh belt (5) connects the separation bin (11) and the material drop bin (12) through the communication opening between the two; an air curtain separating the two bins is provided at the communication opening; a material outlet (9) is provided at the bottom of the material drop bin (12); the top of the separation bin (11) is provided with a negative-pressure air-suction port (6); a material inlet (4) is provided at the bottom of the end facing the conveyor mesh belt (5) on a side wall of the separation bin (11); a vibration groove (3) is provided at the bottom of the separation bin (11); a damping plate (2) is provided at the bottom of the vibration groove (3); an air inlet (1) facing an opening at the bottom end of the separation bin (11) is provided at the lower portion of the damping plate (2); an end of the vibration groove (3) connects to a removed material drop outlet (10). The air-powered separator can separate useless particles of different densities from material according to needs, collect useful material, prevent material particles from breaking and becoming smaller due to mechanical fiction, and has the characteristics of high efficiency, low energy consumption, simple structure, and low material loss.
