Presented at the AusIMM Mill Operators Conference June 2021
ABSTRACT
Vertical stirred mills are more frequently being applied at coarser grinding duties as a replacement for ball milling. This trend is being driven by reductions in footprint and operating cost...

Abstract
The comminution energy curve is a profoundly simple graphical technique that displays detailed operating efficiency information for industrial comminution processes. The database underlying the methodology has recently more than doubled, to now contain a substantial fraction of the interna...

Abstract
As the stirrer speed directly affects the motion of grinding media, and hence the interactions with material particles to be ground, the rotation speed of a stirred mill is well recognised as one of the most important factors affecting the grinding performance.
In this work, the effec...

Abstract
Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented. In the context of the mining industry, interest in stirred milling technologies has grown over the last 20 years where the typical observation reported in the literatu...

ABSTRACT
The stirred milling of nickel laterites offers possibilities for improving liberation and selective size reduction of soft nickel-bearing minerals in laterites. Batch grinding tests were performed in a netzsch™ lME4 stirred mill on siliceous goethitic, goethitic, and saprolitic nickel la...

Abstract
In achieving the necessary liberation for separation of valuable minerals from ores, metallurgists have traditionally selected from the competing options for size reduction devices by making decisions based on various types of costs. While these costs remain important in s...
