PRELIMINARY STUDY OF PARTICLE SIZE MEASUREMENT OF FINE .
Particle size measurement is an important role in the utilization of phosphate rocks for nanofertilizer. In this study, the phosphate rocks from Wonosari and Ciamis were milled by planetary ball mill (PBM) into submicron size ( μm). Measurements of the submicron size were conducted using a dynamic light stering (DLS) method, ...
