>Three Roll Mill 101 - An introduction to a high shear ...
• Milling is to break up pigment agglomeration rather than to reduce particle size. A good rule of thumb of the pigment/oil ratio is to use two parts of oil for one part of pigment. The resultant paste can be passed through three roll mill …
>Cosmetics - three-rollmill
The reduction of particle size and dispersion of the agglomerated blocks are accomplished by the combined rolling force between the roller of the three roll mill and the high shear force caused by different roller speeds. Because all materials are filled into the roller spacing, the particle size is accurately controlled and narrow distribution.
