Foundation Design Criteria For Sag Mill And Ball Mill India

SME 2009 Impact on Grinding Mill Design and Recent New. Breakage tests do not include ball mill grinding data. Based on the 2009 CIM paper (Starkey and s 2009) the ratio of SAG to ball mill grindability is an important factor in achieving a reliable SAG mill circuit design because that ratio reveals the best and most practical split for SAG and ball mill energy for the ore being tested.
