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.

additional crushing stages for increasing the throughput of existing SAG mill circuits [5]. In the case of such modification, the SAG mill product is coarser compared with the corresponding relatively coarse feed size distribution, thus resulting in a higher energy requirement for ball milling in SAB–Semi-autogenous ball mill circuits.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

The filling rate of steel ball in the shell of the semi-autogenous mill is a main item to distinguish SAG mill and autogenous mill. In order to eliminate the impact of the accumulation of rock, the autogenous mill allows to add about 3% of the ball (Φ80 ~ Φ120), SAG mill steel ball filling is generally 8% ~ 12%, even up to 15%.

• Transfer size (T80) is the term used to describe the SAG mill product that is sent to the ball mill. For peak performance and balancing the power available in the SAG mill and ball mill, the transfer size must be measured and controlled. • The transfer size will be 500 microns using a 12mm opening trommel. This can be true under special

A SAG mill, or semi-autogenous grinding mill, is a type of machine used in mining and mineral processing operations. It uses the crushing and grinding action of rocks to reduce materials such as copper ore into smaller pieces for further processing. Unlike traditional mills that rely on steel balls or other media to break down materials, SAG ...

SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...

Ball Mills have a higher degree of efficiency than SAG Mills due to their smaller size and have more area for grinding particles, leading to faster grinding. On the other hand, SAG Mills have a larger and deeper drum that provides larger lifting force which increases grinding efficiency. In addition, due to its larger size, SAG Mills consumes ...
