III. Colloid Mills (CM) • Droplet disruption in colloid mills occurs in a flow channel between a rotor-stator assembly • The rotor may have a large variety of surface profiles (toothed) • Typical rotational speeds are n=3000 min-1 Due to the conical design, the emulsions is transported without external pressure application

How emulsions and emulsifiers work. Simple emulsions are either oil suspended in an aqueous phase (o/w), or water suspended in oil (w/o). Milk is an example of an o/w emulsion, in which the fat phase or cream forms tiny droplets within the skim milk, or water phase. In contrast, margarine is a w/o emulsion containing droplets of water or skim ...

Ball mills are used for small batches of difficult to disperse mill-bases. Ball mills are large porcelain lined rotating drums containing golf ball sized porcelain balls.

The preparation of the emulsion satin paint is given in Table 5. Different batches of emulsion paint were formulated using various amount of core–shell latex along with TiO 2 as pigment in a standard ball mill. In all the paints, the total amount of pigment (TiO 2 + core–shell latex) was kept constant.

The development and processing of emulsions is common in many industries. A manufacturer that uses a tooling lubricant to produce aircraft engine parts or someone applying a cosmetic cream are common examples of emulsion use. The use of colloid mills and in-line mixers is a popular way to prepare and process emulsions.

Bitumen emulsion is produced in special dispersers, ultrasonic homogenizers and colloid mills. These machines vary in the method used for emulsification of the raw material and the quality of the product. Preparation of water bitumen emulsion involves grinding and mixing of bitumen phase in water media and further emulsification.
