Abstract

The mining
industry has a requirement to treat fine (<30 µm) and ultrafine (<10 µm) feed
materials, a target difficult or ineffective for traditional milling processes
such as conventional tumbling ball milling. 
The favoured route has been the use of stirred mills. Stirred mills are
primarily used for ultrafine grinding applications in the mining industry. In
this study, bauxite samples were grinded to ultrafine size (~5 µm) by a
laboratory scale stirred mill and its performance was compared with a laboratory
scale conventional ball mill. The stirred mill
was found to be more efficient (lower grinding time and lower energy
consumption) in ultrafine grinding.
