##tihuan2##Product Quality. Heat generation during the milling process can have a detrimental effect on product quality and destroy batches of highly valuable APIs. Materials containing high levels of fats or oils often prove to be highly heat sensitive. Thus, even a small temperature increase during processing can have a huge effect on overall outcomes.

##tihuan2##Fig. 4 illustrates a typical temporal evolution curve during the milling: the temperature rose monotonically due to heat generation in the mill albeit at a decreasing rate, and it attained a plateau value clearly at 2000 and 3000 rpm. At 4000 rpm, the increase was steeper; while a plateau temperature was approached, it was not attained.
