Wet Particle Size Reduction

Services:

■ Process development for particle size reduction.

■ Scale up: Laboratory to Pilot to Manufacturing

■ New grinding equipment: Design, purchase, installation, start up.

■ Analysis of discreet pass vs recirculation

■ Set up of dispersion testing methods: filtration, stability testing, viscosity.

■ Dispersion instability analysis: issues related to dispersant/carrier/solids interaction.

Experience:

■ Wet milling using horizontal mills, vertical mills, basket mills, 3 roll mills, and high pressure emulsifiers (homogenizers).

■ Dispersions of colorants (including carbon black & TiO2) into various carriers (inks & paint), wax emulsions, and rheology modifiers.

■ Production of ink jet inks, paint, analog printing inks, anti foams, rheology modifiers(silica or clay).

■ Pre-treatment with high shear blades & rotor/stators to form well wetted dispersions with in-line and batch tank units.

■ Chemical analysis of dispersant to carrier and dispersant to solids interaction.
