Between the agsag mill and the ballrod mill, power draw of the latter being relatively stable.In response to the variation in feed size and hardness, the mill feed rate has to be changed significantly 7.The comminution processes such as crushing, grinding, screening and classification are commonly prior to the mineral separation processes.
The primary reason for the significant comminution circuits is because in gold mining the grades are notably low and thus excessive waste material is present, resulting in high mill feed rates.If the ore rock is highly fractured andor brittle, it is likely that an ag mill be the most economical option in lieu of a sag mill.
