The mill building was energized with a temporary 25kV power line, which enabled interior and exterior lighting and also the use of critical components such as the overhead crane. The foundations for the Ball and SAG mills were prepared with concrete and grout works, as well as anchor bolt and sole plate installation.

The SAG mill is usually followed by a ball mill to finish the size reduction prior to the concentration step. In the past when primary, secondary and tertiary crushers fed material directly to large ball mills, the energy efficiency of the concentrator was determined for the most part by the ball mill operation, whereas now the energy ...

Therefore, optimizing the liner structure is of great significance for improving the production capacity and economic performance of the SAG mill. Discrete Element Method (DEM) can effectively analyze the kinematics and dynamics of the SAG mill, and is an effective method for the structural performance analysis of the SAG mill and the liner.

the SAG mill and ball mill was 8658 kW, which caused partial over-grinding. From experience in processing plants outside of China, the power rating of the ball mill should be higher than that of the SAG mill [5]. The pebble crusher had an over-powered configuration. The installed power draw of 630 kW

Optimizing your SAG mill operation - International The optimal performance of AGSAG mills is the key to successful plant operation. All AGSAG mills using radial or curved pulp lifters suffer from inherent material transport problems such as slurry and pebble pooling which decrease throughput and increase energy consumption.
