Homogenizer-disperser or mixer?

Many think that homogenization, dispersion and mixing is the same process. However it is not the case! Mixing without homogenization and dispersion is possible, while homogenization and mixing without the mixing is not.

Homogenization is the process of creating a uniform and stable substance by elimination of microgranularities, which form when mutually insoluble materials are mixed.

Dispersion is a the proces of fine pulverization of solids or liquids, which results in powders, suspensions or emulsions (emulsification). When solid bodies are dispersed, they are destroyed.

A dispersed system is a such where one material (dispersed phase) is distributed in another material (dispersed medium) so that there is a phase boundary between the particles of the dispersed phase and the dispersed medium. An attribute of the dispersed phase is its continuity.

Understanding this, we can precisely determine what kind of equipment is required for mixing (blenders, turbine mixers) and for homogenization, dispersion and emulsification (colloid mills, homogenizers).

One of the best solutions to the problems above is the application of colloid mills.

What is a colloid mill?

The CLM colloid mill is specifically designed for production of highly stable colloidal solutions, superfine suspensions, blends and emulsions. The mill features wet grinding due to the gap between rotor and stator cones being larger at the inlet and smaller at the outlet.

Additionally, the complex geometry of the rotor surface create increased turbulence, which shears particles.

The product in the colloid mill is ground between the rotating and stationary calibrated cylindrical radially skewed teeth of the rotor and stator.

The centrifugal force and high velocity of the rotor relative to the fixed stator cause liquid and semi-liquid materials to become homogenic and finely dispersed.

The colloid mill simultaneously disperses and homogenizes materials.

A heat jacket allows to apply or dissipate heat to or from the grinding zone.

The colloid mill features high performance capacity, allows to produce highly stable emulsions, as well as colloidal suspensions, ensures high degree of homogenization and particle size to 1 micron.

Processes are intensified by 100 – 600% compared with a turbine agitator – colloid mill built into a production line and does not require additional tanks.

Besides, the device creates cavitation, i.e. explosion of caverns by internal pressure.

The colloid mill can be retrofitted into existing production lines.

For high quality grinding the product must enter the mill in certain proportions at constant rate.

The degree of granulation and pumping qualities may vary depending on the mechanical properties of the material and the carrier phase.

Mr. Shekanabo, the United Republic of Tanzania:

“I can only say good things about GlobeCore mills. After seeing the production facility, I had no doubts that this is a serious and reliable company with professional staff, and the system works like a clock. Of course, the production itself seems complicated, but the equipment is powerful and rugged.”
