THE EFFECT OF GRINDING MEDIA PERFORMANCE ON WET MILLING … - Media stress intensity analysis for vertical stirred mills

Agitated media mills stir the grinding media to break down the target material into ultra-fine particles. The grinding media generally consists of spherical metallic or ceramic beads that are stirred into action by the agitator. Agitated media mills are designed in both vertical and horizontal configurations.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 product. They are suitable for both open- …

The efficiency of stirred media mills are influenced by both the operating conditions and physical design of the mill. Using the shear based power model, Radziszewski, 2013, hypothesised that the power draw of a vertical stirred media mill operating with pin or disc type stirrers could be increased by adding stationary liners to the mill shell.1.1 Grinding mechanism of a vertical mill with vane rotors STM/Outotec's HIGmill™ is a "stirred media" grinding mill where the stirred effect is caused by rotating vane grinding discs (rotors) together with stator rings situated on the shell.
