UNIVERSAL EQUATION OF GRINDING KINETICS - …

Grinding kinetics curves In this case the grinding process has a high inertia so it can’t be completed in the allotted time in the mill. The size class content of the finished product doesn’t reach its steady-state value of 100. Such a case often occurs in the production. Also the grinding process has a marked delay within one minute.
