Abstract
In order to determine the efficiency of a dust collector, it is necessary to measure the concentration of airborne dust particles at its inlet and outlet. Measurements were made of the particulate concentration and size distribution in an air-talc suspension across a horizontal circular duct downstream of a Venturi. A cascade impactor was used for determination of concentrations and size distribution of dust in small samples of the suspension extracted from the dust.
