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) .
FINE GRINDING EXPERIENCE WITH VERTICALLY STIRRED BALL MILLS BARIŞTIRMA DEĞÎRMENLERÎNDE ÎNCE ÖĞÜTME ... This paper reports our findings from using a stirred ball mill design and small grinding media, with excellent results in comparision with conventional tumbling ball mills. ... For continuous wet grinding feed pulp is pumped or gravity fed
Hockmeyer specializes in wet grinding and dispersion mills including basket, media and immersion mills used for particle reduction in the paint, ink, ceramics, inkjet, proppants and cosmetics industries.
Wet grinding with vertical stirred ball mills is typically carried out for slurries containing particles smaller than 200 μm, such as industrial minerals and pigments. Filtration is an important unit operation, which is performed in order to reduce the water content of the slurry after grinding .

May 20, 2016· Among the wet media milling processes which use various equipment such as stirred mills, planetary mills, ball mills, etc., the wet stirred media milling (WSMM) has been the most widely used and industrially most relevant process [47,48]. Hence, unless otherwise indicated in this review paper, wet media milling to prepare drug nanoparticles, also referred to as nanomilling, was considered mostly in .
water in a stirred media mill. During the grinding process the created graphiteflakes could be stabilized electrostatically as well as sterically to avoid a rearrangement of the exfoliated sheets. Therewith flake like particles with a thickness in the lower nanometer range were produced in the milling process.
WET GRINDING/MEDIA MILLING. In media milling and nano grinding, particles are dispersed in a liquid by shearing forces (tearing apart), impact or impinging forces (crushed by outside force), and attrition (tearing and crushing each other apart). Custom Processing Services uses the NETZSCH Small Media Mill, the best available technology for this process.

Stirred Milling Technology – A New Concept in Fine Grinding. 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.
The IsaMill is a stirredmedium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older highthroughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
Wet grinding with stirred media mills is a wide distributed unit operation which occurs in many different industrial areas from milliliter to cubic meter scale.

Stirred media mills are usually constructed in the form of a cylindrical drum inside which there are a series of rods, arms or perforated discs which are rotated on a central shaft. The drum is loaded with grinding media, such as metal balls or glass sand.
