The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads. The stirring effect is caused by rotating discs mounted on a shaft. There are also stationary discs on the mill body positioned in between each rotational disc.
Stirred media mills are influenced by a great number of operating variables. A study was conducted to understand the influence of mill speed, feed particle size and, slurry density and rheology on the VXPmill performance. For scale-up, a study was conducted to compare the batch recycle and the pendulum testing procedures.

vertical mill operating principle . Super Fine Vertical Mill Working Principle. Aug 11, 2021 the grinding roller is driven by the hydraulic pressure system to put pressure on the materials on the surface of the grinding disc, extrude and crush materials; at the same time, the grinding disc drives the grinding roller to rotate through the pressurized material, which makes the grinding …
Vertical stirred mills are usually charged with media occupying 80% of the mill volume which is in sharp contrast to tumbling mills that are seldom charged more than 40% of their volumes to allow space for the tumbling action to develop. The stirred mills are charged with a media size of 10–12 mm and operated at a maximum tip speed of 3–8 m/s.
The Operating Principle The Development The first open agitator bead mill by NETZSCH-Feinmahltechnik was developed in 1963 This vertical agitator bead mill was equipped with an eccentric disk agitation system moliNEx which activated the grinding media within a cylindrical grinding tank both axially as well as radially...

Operating principle – gravity-induced stirred mills Gravity-induced mills are in the main slow-speed stirred mills that use high-density media such as steel balls as the grinding charge. The screw rotates slowly such that the ball charge and slurry are not fluidized, but settle under gravity. The screw action pulls the ball charge up the
