The most important feature of AG mill or SAG mill is to feed raw ore from the stope or after crushing the ore to the mill directly. Typically certain mineral grain size ratio to the mill or rod mill. Since AG mill or SAG mill can grind the material to -0.074mm (its content once accounted for more than 20% to 50% of the total product).

The mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models. Models of this type do not predict the particle size ...

The design of the 40 foot diameter SAG mill motor was such that up to a mill operating speed of 74% critical, power would be delivered at constant torque. Above 74% and up to the maximum of 85% of critical speed, constant power would be delivered. The following Figure 2 demonstrates the effect as well as the vendor design estimates.

Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.

As a result, mines have shifted their emphasis in optimization from ball mills to SAG mills. The rock load in the mill essentially depends on ore characteristics and the discharge rate of broken particles through the discharge end. The discharge rate depends on how efficiently the discharge pump (grate and pulp lifters) operates.

October 14th, 2013. An AG mill is a tumbling mill that utilises the ore itself as grinding media. The ore must contain sufficient competent pieces to act as grinding media. An SAG mill is an autogenous mill that utilises steel balls in addition to the natural grinding media (Wills' Mineral Processing Technology, B.A. Wills, 6th Edition).

The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol ...
