The invention relates to a vibration air separation device. The vibration air separation device comprises a material inlet, a powdery particle separation segment and a light and heavy material layering segment, materials enter the powdery particle separation segment from the material inlet, small particles are discharged from a powdery particle outlet after vibration screening, large particles enter the light and heavy material layering segment which is in stepped arrangement, light materials are made to be located at the upper portion of a material layer through falling head and positive pressure airflow, then a separation stage is performed, under guiding of the positive pressure airflow and negative pressure airflow, the light materials move towards the upper left direction, this moment, an adsorbing roller will generate strong negative pressure airflow to make the light materials be adsorbed on the adsorbing roller and rotate towards a light material outlet along with the adsorbingroller, when the light materials move to an air blocking ring, the negative pressure airflow disappears, the light materials fall down and are discharged from the light material outlet, because heavymaterials are large in bulk density and less affected by the airflow, the heavy materials fall directly to be discharged from a heavy material outlet, so that separation of the powdery particles, thelight materials and the heavy materials is achieved.
