Laboratory colloid mill CLM-0.25.1

CLM-0.25.1 colloid mill is designed for homogenization and emulsification of liquid materials (thick slurries of high shear stresses) in a laboratory environment.

CLM-0.25.1 can be used:

  • to prepare laboratory batches of bitumen emulsions;
  • to select the formulation of bitumen emulsion depending on its set of ingredients and field of application.

This colloid mill can be supplied as part of USB-2 bitumen emulsion production units, or as a separate product.

*** As requested by the customer

  • capacity adjustment;
  • corrosion resistance;
  • compactness;
  • selection of the optimal ratio of asphalt emulsion components (recipes);
  • preparation of bitumen emulsion samples for further testing.
  • any type of materials for asphalt emulsion production can be tested in this mill because the mill can be equipped with various rotor/stator tooling, depending on the material and the required process.
