  • Stirred Media Detritors (SMD) Metso

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