Pühler PRK Vertical Stirred Ball Mill The new generation PRK vertical stirred ball mill has been further improved based on the sand mill; it offers high product quality and excellent reproducibility. It is used for stirring, dispersing, dissolving, and emulsifying mixed liquids with various viscosities. Under the action of the stirring teeth, the material undergoes shear, impact, and grinding, breaking down aggregates to achieve homogenization, mixing, emulsification, and accelerated dissolution. It is widely used in fine chemical industries such as paint, ink, coatings, and pigments. Pühler vertical stirred ball mill – customers have learned from experience that it is one of the most versatile devices in their laboratories. Through a wide variety of parts and accessories, it can be simply and cost-effectively assembled and modified. Users can choose dry or wet grinding, add inert gas, operate at controlled temperatures, adjust grinding speed, prevent product contamination, change the size and type of grinding media, and obtain accurate energy consumption information—all on a single machine. Experimental results can be repeated with maximum reliability. Therefore, the PRK Attritor mill is an ideal device for formulation, quality control, and production scale-up research. It is suitable for grinding and dispersing materials that are coarse, hard, or exhibit false viscosity. The material ground by this machine has uniform particle size and fine particles. This machine can also uniformly mix several materials together. It is widely used in coatings, paint, rubber, abrasives, ceramics, ores, coal powder, metal powders, hard alloys, magnetic materials, etc. Special sand mill, vertical type, stirring rod with tungsten carbide hard metal wear-resistant sleeve, causing high shear force and impact force from the grinding media. The stirring shaft is designed according to the fineness of the grinding media to generate high shear and impact forces. The bottom of the cylinder is hemispherical, eliminating dead zones in grinding. A screen is installed at the outlet to separate the grinding media. Closed mechanical design to prevent contamination. Symmetrical arrangement of stirring rods extends the machine's service life. Coolable grinding cylinder. Options: PLC-controlled automated production and cleaning process, adjustable stirring shaft speed. Application areas: High-tech ceramics, coatings, toners, inks, pigments, tungsten carbide, DSM (mechanical alloying), food production, chocolate, confectionery, pharmaceutical industry, chemicals, ferrites, fibers, paper coatings, metal powders, metal oxides, glass, glazes, ores, coal, agricultural fluids.
