As the test in the SKCS is a destructive type, it results in milled fractions of the test wheat which are usually discarded. This work aims at broadening the use of the SKCS from different point of view by measuring the psd of the milled

Prediction of particle size distribution in milling

In the milling process, the control of particle size distribution is necessary for the later physical separation process. Since the milling process is strongly affected by the equipment designs, operation conditions and raw materials, the control for particle size distribution of milling products is mainly based on empirical rules.

MODELING OF SIZE REDUCTION, PARTICLE SIZE

2019-4-21  For modeling the particle size distribution of finely ground particles, produced in milling, plot of log [log 100/(100-y)], or log [log 100/R], vs. log of D (sieve size) are plotted, where y is the cumulative percentage passing through D and R is the cumulative percentage retained on D. Such plots are known as Rosin-Rammler plots.
