Colloid Mill

Colloid Mill

A colloid mill, including advanced colloidal milling systems from Kosmo Engineering, is designed to reduce the particle size of solids suspended in liquids or minimize the droplet size within liquid–liquid emulsions. This process is achieved through the application of high hydraulic shear forces, ensuring exceptional dispersion, homogenization, and emulsion stability. Colloid mills are widely used to enhance the stability and quality of suspensions and emulsions across pharmaceutical, cosmetic, chemical, and food-processing industries.

Product is introduced through the hopper and guided into the precision-engineered gap between the rotor and stator. Here, the material undergoes intense shearing, cutting, and friction between the toothed surfaces, resulting in uniform particle and droplet size reduction. The processed material exits through the discharge port, and when needed, can be re-circulated using a three-way valve and return line assembly for further refinement.

Kosmo Engineering offers a complete range of inline colloid mills—from compact lab-scale units to high-capacity industrial systems.

The Kosmo Engineering Colloid Mill is built for consistent, high-performance dispersion and size reduction. It rapidly breaks down particles and ensures uniform distribution without creating agglomerates. The rotor–stator design generates not only hydraulic pressure but also turbulence and cavitation, resulting in gentle yet efficient grinding, cutting, and homogenization in a single pass.

Centrifugal force drives material into the milling zone, where the large rotor–stator surface area delivers the combined effects required for fine grinding and homogenization. A three-way valve at the outlet enables continuous discharge or re-circulation for repeat processing.
