The search for solution was made in the article to raise the efficiency of the open-type local exhaust and to decrease the dust losses by the closed-type local exhaust-hood into the aspiration system at the expense of the vertical rotating exhaust cylinder. The exhaust is regarded in the form of the slit-type gaps parallel to the z-axes with the drain from the end of the cylinder. The improvements are proposed for the rotating cylinder to increase the air flow entrainment efficiency. The results obtained can be useful when designing of the dust-collecting chambers-capable aspiration hoods.
