HPGR test results published by Grier (1992) on gold ores from the Mt. Todd project showed significant energy savings for a HPGR/Ball Mill circuit as compared to a SAG/Ball Mill plant. By adding a Polycom highpressure grinding roll, the throughput of existing plants can be increased by as much as 150% while simultaneously reducing the power ...

Working Principle of a SAG Mill. The rock and grinding media are placed in the mill and rotated, causing the grinding media to tumble and crush the rock into smaller pieces. The mill operates in a closed circuit with screens that size the ore and send it back to the mill for further grinding. The product from the mill is then sent to a cyclone ...

1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powderlike structures. 3.

Optimising the charge motion to ensure grinding media is hitting the toe of the charge will result in the maximising of ore breakage rates and therefore mill throughput. Trajectory analysis also ensures grinding media is not being over thrown onto mill liners where the impact can lead to breakage of balls and liners therefore minimising ...

The Ball Mill. Much like all types of mills, the Ball Mill's purpose is to grind and blend material into smaller pieces. To do this, the material is fed into the cylinder at an angle and then rotated inside. During rotation, the material travels up the internal wall of the cylinder and then falls back down to the bottom of the structure.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
