Difference Between Sag Mill vs Ball Mill - mech4study
Oct 12, 2017· SAG 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 piec 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
Mar 20, 2017· Semi-Autogenous (SAG) Mills:-SAG mill is similar to AG mills, but utilizes grinding balls to aid grinding just like ball mills It uses a ball charge of approx 6 - 15% SAG mills are characterized by their large diameter and short length as compared to ball mills
Development of a Multi-Component Model Structure for ,
Autogenous (AG) and semi-autogenous (SAG) grinding mills have become popular in the mining industry for their ability to provide a high reduction ratio and deal with high tonnage projects in a compact plant layout AG mills exclusively use ore as grinding media, while in SAG mills steel balls are added as a supplement
