Dry densimetric separation is achieved on a vibrating, inclined base. A flow of rising air crosses this base and has two effects on the material. Less dense products float without touching the base and slide to the lower portion of the inclined table. More dense product contacts the table and is pushed towards the top due to the vibration.

air table suitable for fine (-¼ inch or -6.35 mm) coal cleaning applications was conceived as part of an effort to develop a complete dry separation plant flowsheet for Illinois coal.

Beneficiation of coal fines of size −1.0 + 0.1 mm using an air table under controlled fluidization was investigated. Widely different feed coals with ash values ranging from 30–50% were shown to respond well to the process. Interactions among process variables towards influencing the separation performance were studied carefully to have a firm control over the process.

The system included air supply and separation systems. The air supply system included a roots blower, an air reservoir, a rotor flow meter, and an air valve. The separation system included a gas-solid fluidized bed and an ultrasonic vibration device.
