In order to study the explosibility for agricultural dusts the authors made the explosion tests and measured the explosion pressures. The apparatus used was a so called Hartmann type explosion bomb. The agricultural dusts tested ranged from 200 mesh to 400 in size, 1.5% to 18 in moisture content (d. b.) and 71% to 99 in volatile matter content.The experimental results obtained were as follows:(1) All of the agricultural dusts tested showed rather strong explosibility.(2) Rice husk dust exploded with the whole range of moisture content tested.(3) Both maximum explosion pressure and maximum pressure rise increased with decrease of dust size. The above tendency was remarkable for the latter.(4) Maximum pressure rise decreased with increase of moisture content. On the other hand, moisture content did not influence on maximum explosion pressure.(5) The relation of volatile matter content to dust explosibility was not obviously observed, but the dust in higher volatile matter content showed a tendency to have higher explosive severity.
