The Dust Cyclone used in grain, cereals and food processing plants in the cleaning and annealing unit. Dust Cyclone is used to providing the handling of dust and other light substances in the air coming from cleaning machines When the dust containing air from the dust extractor is fed into the dust cyclone as a tangent, the air contained in the air that loses its speed due to the section expansion decreases with gravity and the fresh air is drained. Thus, the effect of the air outside the factory is minimized.
