A new small-size jet mill of Micronizer-type has been made as an experiment. This paper has clarified the design process of the jet mill and investigated a part of the fine grinding effect.　For the design of the jet mill, the distance needed for acceleration of particles, the diameter of grinding nozzles, the number of grinding nozzles and air flow rate were determined by Rumpf's equations based on several assumptions, and then the power of compressor was determined.　The triboluminessence of sugar indicated that the grinding by the collision between the particles themselves and the friction between the particles rather than by collision with the wall occured mainly in the mill.　It was found that the grinding effect increased with a decrease in feed rate and feed size, and increased with an increase in the grinding nozzle pressure, nozzle diameter and Hardgrove grindability of samples.
