How to mix well
Mixing process & equipment
Slurry quality control

Materials description
 4 ~ 6 fine powders plus 2~3 solvents
 Particle size from a few nano meters to more than 100 microns
 High viscosity and no-Newtonian

How can we obtain desired particle size distribution ?
 Special mixing heads and screens
 Special mixing procedures
 RPM control (high shear option)
 In-line sampling

Mixing procedure & working principle
Mixing process --- Stage1
 The high speed rotation of the rotor blades within the precision machined mixing head exerts a powerful suction.
 Liquids and solids are drawn into the rotor/stator assembly.

Mixing Process --- Stage 2
 Centrifugal force drives the materials toward the periphery of the work head where they are subjected to a milling action.

Mixing Process --- Stage 3

Mixing Process --- Stage 4
