<p>To separate dust e.g. from waste gas obtained during production of cement, lime etc., the gas is passed through a flowing layer of solid particles which trap and entrain the dust preferably through a fluid bed where the dust is separated, and the particles are continuously re-cycled. Preferably, the particles are transported by a mechanic or pneumatic conveying device, and the extracted dust is transported away by a worm screw.</p> |
