A Method How to Predict SAG Mill Grinding Requirements
When these samples were being ground in the 5½'' mill, a 300 lb head sample was obtained from each bulk sample. These 300 lb samples were then ground in the 18″ dry Aerofall mill. The correlation between the grinding work in the 5½ ft mill and the 10″ mill is shown in Table I. The next step was to obtain core samples from the deposit.
