Inside these SagBall mill are big steel balls that grind ore via an impact process. In simple terms, these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being processed. It grinds it up into a compound to make processing easier. Youll find a similar process in sugar cane mills.
Oct 12, 2017018332SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9 to 20.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.
