To explain the phenomena of the transition in particle size distribution in a grinding process, the selection function and the distribution function were determined.
The equation of distribution function obtained experimentally was as follows;
where α is the distribution factor.
The experiment was carried out by the "single-size fraction" method using a Hardgrove machine, a vibration mill and a ball mill. Five kinds of materials were used.
The selection function was found to be proportional to the distribution factor, and the distribution function was a function of ymax and(y/ymax).
