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 mills use less energy with grinding that results in decreased need for grinding media. the wasteful impact breakage of media-to-media or media-to-liner is eliminated, which ensures fewer fractures, and the media inside the mill can maintain its shape and usefulness longer.

Aug 16, 2010nbsp018332nanoparticles can be produced by wet grinding in stirredmedia mills. in the lower nanometer range a true grinding limit exists, where the transferred energy from the grinding media is no longer sufficient to induce further breakage of the particles even
Wet grinding stirred media mills closedtype stirred media mill the design principle of a mill with a disc stirrer is shown in figure 2 the mill is equipped with a rotating gap for the separation of the grinding media today closed type stirred media mills are built with grinding chamber volumes of less than 1
This work investigated the effect of grinding medium size on the wet milling performance in stirred mills using a combined numerical and experimental approach. physical experiments were performed in a 1.4l stirred mill with the discs rotating at different speeds to grind aluminium hydroxide powders with different sized glass beads. the results showed that the
The particles in stirred media mills are stressed and ground between two grinding beads, one grinding bead and a wall or between a grinding bead and an agitator element in zones of high energy density 1, 2, 3. only for a desagglomeration or a desintegration of microorganisms shear forces are a further grinding mechanism.
Wet fine grinding is an important unit process in various industries. in the present work two different stirred media mills one with a cylindrical stirrer one with a disc stirrer and a planetary ball mill are investigated using coupled cfd computational fluid dynamics
