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