Rheological effects on ultra-fine grinding in stirred
For stirred mill grinding the grinding media typically occupies about 80 of the mill volume. Introducing fine beads into a bed of coarse beads would theoretically increase the volume of solid fraction of beads by 24 from about 60 to about 84 . Therefore adding small beads has the potential to increase the charge mass by 40 (24/60) while

Fine Grinding Technology for Mines and Concentrating
The horizontal stirred mill approach for grinding rocks minerals and industrial materials was developed in Australia where it has been used for a number of years. 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

Using stirred media mills in ore grindingTechnologie
· The stirred mill consists of a fixed chamber and several stirrers mounted on a high-speed rotating shaft at the center of the mill. The stirrer design generally fall into three categories depending on the application discs pins or skews. The rotating shaft transfers its momentum to the grinding media. Stirred mills are classified based on

Stirred Media Detritors (SMD) Outotec
Stirred Media Detritor (SMD) is a fluidized media grinding mill. It utilizes the rotational energy of the impeller arms to impart a high-energy motion to the media and slurry mixture inside the mill. This results in particle-to-particle shear and compressive forces that produce the desired grinding mechanism for fine grinding.
