The first problem will ball mills is that we cannot see what is occurring in the mill the other problem is that many of the independent variables are nonlinear or have paradoxical effects on the end results in ball milling of dry solids the main independent variables are mill diameter mill speed media size solids loading and residence ## Mill Speed Control Using Programmable Logic

We obtain a critical speed of 037 hz hence critical speed in revolutions per minute is c n hz ⋅ 037 60 222 rpm in this case critical speed is 22 rpm but ball mills usually operate at 65 to 75 of the critical speed hence operating speed is approximate 16 rpm the mill is usually divided into at least two
