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 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 Grinding,Unlike tumbling mills, where comminution occurs from both impact and attrition grinding, in stirred media mills the particles suffer almost entirely attrition breakage between the beads. (Napier-Munn et al., 2005). In stirred mills there are no free-falling possibilities forStirred mills - for wet grinding - Metso,Stirred mills are used for wet grinding. Ideal for grinding finer products, stirred mills are known for operational efficiency and smaller required floor space. Metso offers both gravity-induced and fluidized technologies in Vertimill® and Stirred Media Detritors (SMD), allowing for the optimum equipment solution for
