SF Series Vertical Bead Mill – Screenless, Vapor-Phase Sealed Grinding System

Series Overview:

• Vapour-Phase seal structure: The mechanical seal only comes into contact with air and not with grinding media or slurry, which greatly extends the mechanical seal's life and significantly reduces the maintenance rate.

• Suitable for applications involving solvent media, preventing material oxidation and solvent evaporation pollution.

• Screenless: Dynamic centrifugal particle separation system, no clogging, no need to clean the screen or particles.

• The materials for the grinding cavity and components can be customized according to customer requirements: zirconium oxide, silicon carbide, silicon nitride, polyurethane, alloy steel, etc.

• Zirconium beads with a diameter of φ0.1∼1.5mm can be used to achieve controllable grinding at the micron, submicron, and nanometer levels.

• Suitable for ultrafine grinding of materials such as silicon nitride, aluminum nitride, titanium carbonitride, tungsten carbide, and MLCC.
