Can be ground to the finest particles using dry grinding. 'STJ Series' <Ultrafine Grinder>
FS-4, STJ-200, STJ-315, STJ-400, STJ-475, STJ-560, STJ-670, etc.
An ideal air flow grinder for those struggling with equipment wear, adhesion during grinding, grinding heat, and the cleanability of the grinder.
This is a horizontal jet mill suitable for ultra-fine grinding of hard and easily wear-prone powder materials. You can choose liners suitable for the crushed material, including alumina and silicon nitride, for the internal liner. Additionally, all contact parts such as the inner surface of the mill and nozzles can be made of ceramic, eliminating concerns about wear. Particularly, due to its excellent sanitary properties, it is a widely used device in pharmaceuticals and pesticides.

basic information
【Features】 ○ Since it crushes using compressed air, it can achieve sub-micron level fine grinding without applying heat and losing the properties of the material. ○ It can produce ultra-fine powders that cannot be obtained with other grinding machines. ○ The generated particle size can be controlled uniformly and sharply, allowing for grinding with excellent dispersion and fluidity. ○ Since grinding is predominantly due to the mutual collision of the crushed materials, there is minimal wear on the main body and contamination from foreign substances. ○ With an aluminum liner as standard and no drive components, there is no risk of contamination. ○ The simplified internal structure allows for easy disassembly and cleaning. ○ A wide selection of models is available based on processing capacity. ○ By using gases such as N2 and Ar in the fluid, grinding in an inert atmosphere is possible. *For more details, please feel free to contact us.

Company information
To create high-quality products, powder technology is an essential foundational technology. Since our establishment in 1968, we have consistently strived to acquire high-level powder technology. In particular, our contract processing division has become our mainstay, having cultivated extensive experience and achievements. We have responded to a wide range of customer requests, handling the processing of many materials and refining various processing techniques such as crushing, classification, mixing, drying, coating, and compounding. The fine powder products developed using the processing technologies gained from our extensive contract processing experience are our original offerings. These products utilize our unique chemical grinding technology, enabling us to achieve a level of grinding that cannot be obtained through other grinding methods, as well as allowing for special processing such as compounding with inorganic materials, compounding between resins, and surface coating.
