The Effect Of Ball Milling On Particle Size Of Coarse Sugar

A series of lactose granulations made with various amounts of starch paste and water was subjected to milling through different screens and the particle sizes were determined the distributions were log‐normal when the size of the coarse material was determined by sieve analysis and the size of the fine material was determined microscopically.
