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. Lower capital cost

What is Single & Double Side Fine Grinding?
Fine Grinding (flat parts – single or double-side) is the abrasive machining process for removing material using a bonded Superabrasive wheel at low speed with a liquid to keep the part cool. The fixed grain of a geometrically indefinable cutting shape acts like a plow (fig. 3) and material is removed by micro-grooving /-cutting (fig. 4).
