Explain the difference between Stirrer and Disperser

Dispersers and mixers have different applications and working principles in the field of liquid mixing and stirring. Here are their differences:

How it works

Disperser: The disperser evenly disperses particles or solid substances into the liquid medium through the mechanical force of high-speed rotation or vibration, so as to achieve the purpose of uniform mixing and dispersion. Dispersers usually have high-speed rotating stirring devices, such as dispersion discs, grinding balls, etc.

Mixer: The mixer mixes the ingredients in the liquid or mixture evenly through the rotation or vibration movement of the stirring device (such as stirring paddle, stirring blade, etc.) to achieve the purpose of stirring and mixing. Mixers are usually used for stirring, dissolving, mixing and other processes of liquids.

Main application:

Disperser: Disperser is mainly used in coatings, inks, dyes, cosmetics and other fields to uniformly disperse solid particles into liquid media to obtain a uniform dispersed liquid or slurry.

Mixer: Mixers are widely used in chemical, pharmaceutical, food, beverage and other industries to mix and stir various liquids or mixtures of liquids and solids.

Equipment structure:

Disperser: Disperser usually has a high-speed rotating dispersion disc or grinding ball, which disperses solid particles into the liquid through the force of high-speed rotation. The structure and accessories of the disperser are usually designed to achieve high-speed dispersion and grinding functions.

Mixer: The mixer usually has a stirring device such as a stirring paddle and a stirring blade, and the liquid is stirred and mixed by rotating or vibrating the stirring device.

It should be noted that dispersers and mixers may have overlapping application fields in some cases, and there may also be differences in specific equipment design and working principle. Therefore, when selecting and using equipment, the most suitable type of equipment should be determined according to specific application needs and process requirements.
