Before we go any further in our discussion of machines, which disperse materials, the term ‘dispersion’ requires an explanation.
Dispersion is a process of making a uniform substance from two or more mutually insoluble substances. The first of the materials (dispersion phase) is finely distributed in the second material (dispersion medium), and the resulting product remains stable for a long time.
One of the most elegant solutions to the problem of dispersion is the use 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 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 mill simultaneously disperses and homogenizes materials.
A heat jacket allows to apply or dissipate heat to or from the grinding zone.
The 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%.
Besides, the device creates cavitation, i.e. explosion of caverns by internal pressure.
The 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.

Clients speak about GlobeCore mills:
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.”
Mr. Patel, the United Republic of Tanzania:
“I want to wish GlobeCore success in the future and I think we will maintain our cooperation for many more years. May you have as many successful products and new developments as possible.”
