No 1 rod mill/ball mill circuit was operating very effi ciently when comparing the combined operating work indices for both mills with the rod mill and ball mill laboratory work indices. Note, in Figure. 1, that the rod mill product slope
The Bond equation is used to calculate ball mill specific energy from T 80 to the final product P 80 size. The total circuit specific energy is the sum of the SAG mill and ball mill specific energies. W SAG = R.(Ms+16000)/(Ms.W T
The circuit comprises a SAG mill, 12 m diameter by 6.1 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW
milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further with the ...
