Product Introduction

It adopts patented screenless centrifugal separation, with models ranging from 30L, 60L, 90L to 150L, suitable for pilot-scale development and large-scale mass production. The grinding media can be as small as below 0.1mm. Thanks to the special rotor structure material and cylinder design, it can grind nano-silicon to below 80nm, which greatly improves production capacity and efficiency while solving the industry pain point of grinding media leakage in centrifugal separation.

Performance Features

1.Outstanding ultra-fine grinding and anti-leakage advantages

The screen-free design is compatible with grinding media of 0.05mm or smaller, enabling ultra-fine grinding to below 100nm.

Equipped with centrifugal separation + special filtering structure, it achieves zero bead leakage during operation, solving industry pain points.

2.Excellent grinding efficiency and uniformity

The slit-type grinding chamber features high energy density and rational flow channels, ensuring superior efficiency and uniform particle size distribution.

3.Reliable, eco-friendly, and easy to operate

Patented mechanical seal with optional solvent sealing, eliminating the risk of material contamination and ensuring long service life. Supports one-click import and export of formulas, making operation simple and easy to master.

4.Energy-efficient with excellent temperature control

The rotor is optimized through simulation to enhance media collision while reducing contact with the rotor and cylinder wall, resulting in high grinding efficiency, excellent temperature control, and low energy consumption.
