Energy Saving Ball Mill Working Principle: http://www.kf-machinery.com/energy-saving-ball-mill.html This energy saving ball mill has two warehouses and its outside runs along the gear,the material enters spirally and evenly to the first warehouse of the milling machine.In this warehouse, there is a ladder scale board or ripple scale board, and different specification steel balls are installed on the scale board, when the barrel body rotates and then produces centrifugal force, at this time, the steel ball is carried to some height and falls , thus to make the material grinding and striking.After coarse grinding of the first warehouse, the material then enters into the second warehouse for regrinding with the steel ball and scale board.In the end, the powder is discharged by output material board and the process of grinding iscompleted.
