Roller Mill And Particles Sizes And Speed Differential
Roller mills: Precisely reducing particle size with. called the roll speed ratio (or roll speed differential). For instance, if one roll rotates at 1,000 rpm and the other at 500 rpm, the roll speed ratio is 2:1 (1,000/500). More shear — and thus a larger roll speed … Keep Reading
Cosmetics - three-rollmill.com
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.

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 …
Roller mills: Precisely reducing particle size with ...
How the mill achieves uniform particle size To achieve a uniform final particle size with minimal fines, the roller mill must have the right roll surface, roll speed ratio, and roll gap for your application. Roll surface. Typically, the roll surface is corrugated rather than smooth to achieve efficient size reduction, as shown in Figure 3.
