Colloid Mills | Grinding Mills

Colloid mills and grinding mills are your best answer for particle deagglomeration and primary particle size reduction.  Sonic’s RotoMill rotors and stators are designed with a patented and proven multi-angular system to provide superior shearing and grinding. There are 3 shear points that subject material to a higher degree of grinding than conventional mills. Undispersed material is forced into a cavity formed by a spinning Rotor and fixed Stator; centrifugal force propels the material to the outside of the Rotor, causing intense hydraulic shear that breaks agglomerates and homogenizes the solids and liquids.

Colloid Mills Modern Features 

  • Improved Housing with triple bearings for improved life and stability
  • Removable Bearing Chamber allowing easier access and maintenance
  • Removable Seal Chamber allowing easy seal change and easy swap over to double Flush Seal
  • Double Flush Seal assembly for sanitary applications
  • Insertable Stator easier to use and creates larger cooling area to prevent heat expansion
  • Pressures up to 200 PSI
  • Flows from 0.25 to 100+ GPH

Grinding Mills Common Applications

Milling is a common requirement in the chemical industry to deagglomerate liquid slurries or reduce primary particle size in wet solutions. The particle size reduction of Bitumen slurries for example is critical for the use of Asphalt. Thickeners such as metallic soaps, like aluminum or clay, need to be deagglomerasted to provided better overall performance of Greases.

Colloid Mills Common Applications 

  • Aggregates and Binders dispersions
  • Asphalt slurries and emulsions
  • Bitumen slurries
  • Cements
  • Clay dispersions
  • Inks and Paints
  • Rubber compounds
  • Sodium dispersions
  • Talc dispersions
  • Greases; thickeners and additives
  • Titanium and Zinc dispersions
