Dust scrubbing using water sprays is one of the most common techniques for airborne respirable dust control in the mining industry. Measurement of spray characteristics such as drop size and velocity using state-of-the-art laser instruments (Phase Doppler Particle Analyzer) will provide detailed information for a better understanding of wet scrubbing mechanisms such as inertial impaction, interception, and turbulent diffusion. All previous wet scrubber performance calculations were based on measurements of dust size and concentration as a function of water flow rate, water pressure, and average drop size. The real spray process undergoes dynamic changes so that it is necessary to determine spray characteristics such as drop size and velocities in both radial and axial directions.
