#### Mill Speed Control Using Programmable Logic Controllers

the critical speed, and ball mills usually operate at 65% to 75% of the critical speed. Ball mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being
