An experimental study on the fine grinding of calcite powder (d 50 = 62.16 μm) using a 0.75 l laboratory stirred ball mill has been carried out.The effects of various operating factors, such as grinding time (min), stirrer speed (rpm), slurry density (wt.%) and ball filling ratio on fine grinding was studied under batch wet conditions using alumina balls, 95% purity with diameters 3.5–4.0 mm.

Figure 10.1 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy required to achieve the grind lessens.

Conventional ball mills rotate the mill body (a horizontal cylinder), tumbling both rock and metallic balls. Stirred mills use an internal auger to agitate the feedstock (ore which is fed into the mill as a slurry) and grinding media (sand, ceramic balls), which produces finer, more uniform grind sizes with reduced energy consumption.

Stirred ball mill grinding is an important process in reducing the size of ceramic micro- and/or nanoparticles to a desirable range to be used as a constituent for micro- and nanostructured materials. In this study, ...

The attritor ball mill, also known as stirred ball mill, is a kind of vertical ball mill. It can be divided into dry type and wet type, suitable for grinding a variety of materials, such as industrial ceramics, fireproof materials, silicate materials, metal powder, ores, etc. It is equipped with an agitation system inside the grinding cylinder.

system geometry. In stirred ball milling, the mill con­ tains the solids being ground, the liquid (in wet grind­ ing) and, more importantly, the grinding media.

al., 2005). In stirred mills there are no free-falling possibilities for grinding media, meaning that impact action does not occur. The bead size is small, typically 1 to 6 mm which means a large amount of contacts and high grinding efficiency especially in the finest range, where ball mills are not effective or cannot reach P80 10 to 40 µm.
