The article explores the dust dynamics in an aspiration hood equipped with various thin mechanical shields. A differential equation of motion of dust particles is used to calculate their trajectories, and the velocity fields of the air flow are calculated by the method of boundary integral equations. The influence of different mechanical shields on the maximum diameter of dust particles is determined. The results demonstrate that by using curvilinear mechanical shields, dust extraction into the aspiration network can be significantly reduced.
