Optimization Of Ball Milling Parameters To Produce

Nov 11, 2013 However, no significant reduction in particle size was observed after an extended milling time of 4 to 8 h. This is due to the fibrous structure of plant material itself which limited further size reduction . An increase of particle size from 237.1 to 581.13 nm was observed as mass concentration is increased from 0.4 to 2.8 wv.
