STUDIES OF PARTICLE—SIZE DISTRIBUTION AND ITS CALCULATION METHOD OF FEED STUFF GROUND BY HAMMER MILLS

The screening results of the samples of corn meal ground by four types of hammer mill available and soybean meal,ground salt and oyster shell meal ground by rotarydisc aired hammer mill were analysed.It was discovered that the particlesize distribution of the material ground by a hammer mill follows the Logexponential Law. The new distribution function of particle-size and the equations used to evaluate the mean particle-size and standard deviation appear in this paper.
