A Study of Laser Diffraction Measurement for Particle Size Distribution
Zhang Yimo, Mao Yi, Tian Xuefei(Institute of Modern Optical Instrument, Tianjing University)
A design principle of laser particle analyser for spraying atomizing analysingand solid state powder particles is put forward in the paper. The mathematicalmodel is given and systematic software is programmed. The spraying atomizinganalysis and catalyst graininess measurement on fluidizing bed are carried out bythe practical instrument. The measurement proves that the design principle iscorrect and the instrument is successful.
