Stirred Media Detritor (SMD) is a fluidized, vertical stirred mill designed for optimum grinding efficiency for fine and ultrafine grinding products. SMDs have the capacity to operate continuously at full load power draw with no steel contamination of the …

The wet fine grinding experiments were performed in a vertical stirred mill. Four significant operating variables stirrer speed, grinding time, feed size, and solids concentration were investigated for their effect on the performance of stirred mills.

monitoring, ball milling, rougher flotation, rougher concentrate regrinding and cleaner /recleaner flotation. The rougher concentrate is reground in an IsaMill, which is a stirred mill that operates with inert silica sand grinding media. For this project, Anglo Platinum required a stirred mill of a unit size not previously available.

Jankovic [6, 7] investigated the effect of grinding media in a vertical stirred pilot mill and found that 6.8 mm steel grinding media were more effective than coarser (12 mm) grinding media while ...
