    In order to get the basic information on the generation of grain dust from rough rice, the auther measured the quantity of dust which discharged from rice drying and processing facility. The results obtained were summarized as follows;
(1) The rough rice dust were measured in following classified three steps ; fine, intermediate, and coarse dust. These were recognized that the variation of dust quantity was not large at the process of rough rice drying, and was discharged in stable rate, comparatively.
(2) Based on the measured results, the rate of dust which discharged from 1 tonnage of rough rice was 1.059 kg/ton in coarse dust, 0.251 kg/ton in intermediate dust, 0.308 kg/ton in fine dust, and 1.618 kg/ton in total of the dust.
(3) It was proved to show the particle-size-distribution of grain dust, the Rosin-Rammler's chart and Rosin-Rammler-Bannet's equation were available, And it was examined on R.R.B.'s equation between measured value and calculated value.
