Stirred Media Detritors (SMD) Metso 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. Lower capital cost

Stirred Milling Technology A New Concept in Fine

2019-5-8  STIRRED MILLING TECHNOLOGY Mill structure 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

Stirred media mills in the mining industry: Material

2020-6-1  Stirred media mills. Efficient grinding of fine and ultrafine particles requires small media to increase the surface area and the consequent collision frequency, but ball mills are fundamentally limited in the momentum that can be applied to such small beads by the force of gravity, which sets a practical lower limit in media size.

2021-8-26  Stirred media mills, also referred to as stirred ball or stirred bead mills, generally have a good ability to produce fine particles with a relatively narrow particle size distribution. Wet grinding with vertical stirred ball mills is typically carried out for slurries containing particles smaller than 200 μm, such as industrial minerals and
