AMIT 135 Lesson 7 Ball Mills Circuits

A rotating mill charged with media and ore is lifted against the inside perimeter Some of the media falls and impacts the ore particles at the bottom of the mill The rest of the media cascades and in the process creates particle breakage by attrition The process is continuously repeated as the particles move by mass and volume action through the mill Dry and wet grinding common Ball
