Grinding and dispersing in stirred media mills is a process, which is widely used in different industries such as chemical, ceramic, pharmaceutical, filler, ink and cosmetic industry. Stirred media mills belong to the group of mills with free movable grinding media.
Fig. 1. Grinding chamber of laboratory stirred media mill. Since comminution of hard ceramic materials not only causes grinding beads wear but also considerable wear of stirrer discs and grinding chamber wall, stirrer discs made of wear-resistant polyurethane and a grinding chamber coated with polyurethane are used.
A pilot-scale grinding technology of ceramic medium stirred mill was proposed in this study. Based on the specific productivity and grinding efficiency, the appropriate grinding parameters were ascertained as follows: material ball ratio of 0.7, ceramic ball medium size ratio (10 mm: 15 mm: 20 mm = 3:2:5), stirring speed of 110 rpm, grinding concentration of 50%, and medium …
Grinding media sizes used in Attritors range from 2mm to 10mm. For the ceramic industry, grinding media com-monly used include alumina, zirconium steatite ceramic, silicon nitride, silicon carbide, glass beads, tungsten car-bide. With theses combinations of speed (arm tip speed) and masses (media weight), the Attritor action creates powerful ...

Using ceramic media with properties tailored to high intensity stirred milling further increases energy efficiency and extends the practical operating range of these mills to coarser feed and product sizes. Historically, the economics of using ceramic media types in stirred mills in the minerals industry has not been attractive.
Stirred Media Detritor (SMD) is a fluidized, vertical stirred mill designed for optimum grinding efficiency for fine and ultrafine grinding products. SMDs have the capacity to operate continuously at full load power draw with no steel contamination of the product. They are suitable for both open- and closed-circuit operation.
2338 stirred ceramic media grinding mill. Ball Ball Mill Ceramic Grinding Media Product on Alibaba. Stirred mills use an internal auger to agitate the feedstock (ore which is fed into the mill as a slurry) and grinding media (sand ceramic .

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

significantly increasing grinding efficiency. 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 for grinding media, meaning that
STM's scope includes the design and delivery of one Vertical Power Mill VPM10 grinding mill, vertical stirred mill using ceramic grinding media, complete with its user-friendly control system and 1,600 kW drive system. The duty of the VPM mill is to grind 140 t/h of gold concentrate from 2 mm to P70 of 75 µm.
ceramic grinding media of various compositions being generally employed. Efficiency of operation, stirred mill type, and quality control are important factors in this selection of media; but the major reason has been the relative hardness compared to feed materials in MIG stirred milling installations.
