AMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill
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 ...
