Star Burst™

Wet Pulverizing and Dispersing Device

The solution for super fine particles.

The "Star Burst" is a wet-type pulverizing - or wet jet milling - device to disperse, emulsify, pulverize, and reform surfaces of raw materials by obliquely colliding the particles pressurized up to 245 MPa at the relative velocity of Mach 4 .


Minimum Contamination
Star Burst does not use any grinding media, resulting in a minimum amount of contamination.

Homogenized Particle Size
Uniform particle with narrow particle size distribution can be achieved by controlling the injection speed of raw material slurry.

High Pulverizing Capability
Nano-level pulverizing or dispersing is effectively achieved in a short period of time without short path of raw materials.

Various Applications
This device is capable of pulverizing raw material slurry with a viscosity of up to 5,000 MPas or up to 50 wt%. Slurry with hard particles is also applicable, by using our original sealing structure and nozzle made of single crystal diamonds.
