Ideal for research institutes, universities, R&D centers, and advanced materials laboratories, the W Series provides reliable process development with seamless scale-up to industrial production.


SF-Series Vertical Sand Mill
This vertical sand mill features a vapor-phase mechanical seal for longer service life and low maintenance, a screenless centrifugal separation system for clog-free continuous operation, and a high-efficiency grinding chamber for micron to nanometer-scale particle size reduction. Compatible with Ø0.1–2.0 mm zirconia beads, it offers excellent cooling, customizable wear-resistant materials, and is ideal for ultrafine grinding of advanced ceramic and electronic materials.
SD-Series Dual-Power Vertical Sand Mill
The SD Series Dual-Power Vertical Sand Mill features a dual-motor, dual-shaft drive system with independent speed control for the stirring rotor and separation turbine, enabling precise process optimization and superior grinding performance. Its advanced screenless centrifugal separation technology, vapor-phase mechanical seal, and variable-frequency control deliver high grinding efficiency, stable operation, low maintenance, and excellent particle size distribution. Designed for nanometer-scale applications, it achieves particle sizes as fine as 20–50 nm using ultra-fine grinding media, making it ideal for advanced materials, electronic materials, inks, coatings, and other ultrafine dispersion processes.


F4-Series Laboratory Sand Mill
The F4 Series Laboratory Sand Mill is an upgraded version of the W Series, offering enhanced flexibility and efficiency for laboratory grinding and dispersion. Featuring interchangeable 0.05 L, 0.1 L, 0.3 L, and 0.5 L grinding chamber configurations on a shared machine platform, it accommodates a wide range of sample volumes while reducing equipment investment. With optimized speed settings and a modular design, the F4 Series delivers precise, consistent, and cost-effective performance for research, product development, and pilot-scale applications.
WS-Series Horizontal Bead Mill
The Large Horizontal Mill is engineered for high-volume, energy-efficient grinding with advanced bead separation technology for uninterrupted operation. It supports a wide viscosity range (20–5000 mPa·s) and nanoscale grinding using media as small as 0.2 mm. Its optimized grinding structure, modular rotor options, and silicon carbide grinding chamber deliver high efficiency, narrow particle size distribution, excellent wear resistance, and low product temperature. Equipped with a high-efficiency permanent magnet motor, the mill reduces energy consumption by over 20% while ensuring reliable performance, easy operation, and low maintenance.
