Across Indonesia’s and Kazakhstan’s fine chemical, pharmaceutical, food additive, and new energy material sectors, particle size control has entered the era of micron-level competition. Screening ultra-fine powders at 200, 300, or even 500 mesh requires equipment that delivers high mesh penetration without damaging particle integrity, while also solving the chronic problem of blinding caused by static and moisture. The YBS series gyratory sifter is purpose-built for these demanding applications.
The standout feature of the YBS sifter is its gentle yet effective motion. The screen body performs a smooth, uniform planar rotation, and material fed at the center spirals slowly outward across the mesh. Unlike vibratory screens with violent vertical throwing, this movement gives particles ample but soft contact with the screen surface. Ultra-fine powders pass through efficiently, while fragile granules remain intact. This is a critical advantage for products that must retain their shape and integrity — such as catalyst carriers, crystalline materials, and granulated fertilizers.
In Indonesia’s fine chemical and food additive industries, the YBS gyratory sifter is widely used to classify titanium dioxide, calcium carbonate, citric acid, plant extracts, and other ultra-fine powders. All product-contact parts are made of SUS304 or SUS316L stainless steel, and the sealed construction meets food-grade and pharmaceutical hygiene standards. To prevent blinding caused by static or moisture, the YBS can be fitted with an ultrasonic de-blinding system, keeping meshes clear and throughput high even above 300 mesh. In Kazakhstan, the same machine reliably handles pharmaceutical intermediates, metal powders such as cobalt, nickel, and tungsten, and fine mineral powders, helping producers meet export-grade specifications.
Compared with European and American gyratory sifters of the same class, the YBS series delivers equivalent core screening performance at a purchase price typically 30–50% lower, with much shorter spare parts lead times — an outstanding value proposition for Asian customers. Its low operating power and minimal dynamic load eliminate the need for heavy foundations. The fully enclosed design prevents dust leakage, supporting compliance with increasingly strict environmental and occupational health regulations in both countries. If you are seeking a better solution for ultra-fine powder screening — in precision, capacity, or cost — the YBS gyratory sifter deserves a closer look.
