How To Choose The Right Mixer For High-Viscosity Mixing Applications

A few years ago, the process of selecting a mixer for most applications was straight- forward. When increased demand required an increase in production, process engineers were naturally inclined to choose the type of mixer that had worked before in the same application. When they began talking to equipment manufacturers, their questions focused on capacity, auxiliary equipment, projected delivery and price. Many tested equipment before signing a purchase order. By Charles Ross and Son Company

Improvements To The Mixing Step Can Lead To Big Rewards

A semi-continuous process is beneficial to maintaining a clean and streamlined batch mixing operation without compromising the level of control over discrete units of production. The semi-continuous mixing procedure is achieved by utilizing a change-can design mixer. With multiple vessels, one mix could be at the loading stage, another under the mixer, another at the discharge step, and yet another at the cleanup stage.

Understanding Surfactants And New Methods Of Dispersing Them

Surface-active agents, or surfactants for short, are compounds that lower the surface tension of a liquid and lower the interfacial tension between two liquids. Surfactants are amphiphilic in nature, possessing both hydrophilic and lipophilic properties. The unique combination of these opposing properties in the same molecule is what enables a surfactant to reduce surface and interfacial tensions. Submitted by Charles Ross and Son Company
