Abstract
A dust generator was developed to produce dry dust from powderous materials for instrument calibration and laboratory studies. The powder is fed at a constant rate via a chain conveyor into a fluidized bed where the particles are deagglomerated and aerosolized. The powder feed rate is variable from 1.2-36 mm3/min and the air flow rate from 9-30 l/min. Aerosols of coal, silica, potash, rock and Arizona [USA] road dust were successfully generated for calibrating optical particle counters and aerosol mass monitors.Keywords
