#### The spiral jet mill cut size equation

WEBOct 1, 2016 · Theoretically, the spiral jet mill has a size of particle ( dcut) that will remain balanced at the grind chamber exit with equal drag and centrifugal force. Fig. 3 illustrates the forces balance for a particle at the grind chamber exit. The forces balance can be solved for cut size ( dcut ): d cut = k 1 v r 2 v t 2 where k1 = 3 CDρgr /4 ρp ...
