The main drawback of SAG - high power consumption. To reduce power consumption, I think: The right determine of SAG feed size. This depends on the mill diameter and the ball size. Feed size necessary to take 80% of the maximum piece of ore that will crushed by the balls. For the big SAG more than 8 meters optimal feed size will be - 50mm.

>Total primary milling cost reduction by improved liner design
AG liner used in SAG (UG2) Plant B was designed to run with the primary mill as an autogenous mill (AG) but it was decided to use balls in the primary mill. The liner design was retained resulting in very high grinding media wear rate (1200 g/t). A new liner design was proposed to the plant in order to reduce media wear. This new design (see ...
>Factors Affecting Ball Mill Grinding Efficiency
The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
>CHAPTER 1: INTRODUCTION 1.1 PROBLEM STATEMENT
academic achievers often lack interest in schooling, and have poor future prospects. They are also more likely to fall pregnant and consequently drop out of school than their peers who perform well (Coley & Chase-Lansdale, 1998). This line of argument suggests a causal relationship between poor academic performance and adolescent pregnancy. Thus
>Optimization of mill performance by using
Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time.

It is then logical to expect that the end liners do not reduce the effective mill length. Another main factor influencing the SAG mill performance is the charge motion inside the mill which has been studied in detail (Rogovin and Herbst, 1989, Morrell, 1992, Powell, 1993, Boateng and Barr, 1996, Mellmann, 2001, Ding et al., 2002, Santomaso et ...
