Dust characteristics and movement laws of metal polish
Summary：In this paper, the characteristics of the dust grinding process produced car body and the movement of research. Its purpose is to better understand the metal dust in the processing and handling of risk, in order to better prevent dust hazards incidents. Metal dust mostly combustible dust, under certain conditions occur dust explosion. Therefore, the metal dust, the study of the characteristics and the law of motion is necessary. Through the study of the dust characteristics and regular exercise, you can know the dangers of dust, in order to better control the dust, to avoid dust explosion. Contents of this work include: the production of dust generated, collected through the ventilation and dust removal equipment, dust samples were tested and motion simulation. Where experiments are mainly: Comprehensive Experimental powder dust cloud ignition test experiments, dust layer ignition test experiments, 20L ball experiment. Through experiments to understand the main danger of dust explosion risk sample, which is the prevention of dust explosions have great significance.
Keywords: Dust characteristics; sports law; dust explosion
