Colloid mill CLM-16/25
The CLM-16/25 colloid mill is designed to homogenize and emulsify liquid products, particularly thick slurries with high shear stresses, with a primary focus on preparing bitumen emulsions. However, it is versatile enough to be utilized for the preparation, dissolution, and processing of various products across different industries.
Operating on the principle of a rotor/stator system, the CLM-16/25 mill comprises concentric tool rings, such as cutters and knives, with specialized configurations of grooves and holes to ensure optimal mechanical impact on the processed product. In operation, the tool rings of the rotor and stator align coaxially and rotate contact-free at high speeds, facilitated by axial and radial gaps.
The processed product enters the mill housing through the axial bore of the stator (product inlet), traverses the rotor/stator system, and exits radially (product outlet). During this passage, the product undergoes complex hydrodynamic processes, including changes in shear stresses, shear forces, and flow velocity. The increased contact surfaces of chemical agents within the rotor/stator system accelerate chemical reactions, resulting in intensive dispersion, emulsification, homogenization, grinding, and pulverization of the processed product.

ADVANTAGES
- The mill is versatile, finding applications across various industries.
- It features compact sizes, making it suitable for different settings.
- The mill offers a range of rotor/stator tooling options, including nozzle, chamber, cone (for milling), and cone (for viscous products).
- Depending on the desired intensity of mechanical and thermal processing, users can select the appropriate rotor/stator tooling type and number of operating stages (rings). These tools can be collapsible or made from solid workpieces, with different grades of steel available based on the intended purpose and optimal tool geometry for the task.
- The mill can be operated both indoors and in sheltered outdoor spaces, offering flexibility in usage environments.
