Mechanism of Action. Colloid mills fall under the category of rotor-stator mixers. In this model, a quickly rotating rotor draws the sample up; it is then pushed in a centrifuge-like fashion through a stator that contains many small slots. The combination of high rpm from the rotor and exit through tiny slots allows the sample to be ...
