Working principle of dry powder mixer

Dry powder mixer is a commonly used equipment for mixing different types of powdered materials. Its working principle is basically to fully mix and stir the powdered materials through mechanical force to achieve a uniform mixing effect.

Dry powder mixer usually consists of a container and one or more rotating stirring elements. When the equipment is started, the stirring element starts to rotate and brings the powdered materials into the container. The design of the stirring element usually includes scrapers, spirals, stirring arms, etc. to ensure that the materials are fully mixed in the container.

During the mixing process, the materials are constantly subjected to shear, extrusion and impact forces, which cause them to intertwine and disperse with each other. This will cause materials of different particles to contact each other and form more contact points on the powder surface to increase the uniformity of mixing.

At the same time, the mixer can also improve the mixing effect through some additional auxiliary equipment. For example, air flow or vacuum system can be added to control temperature, humidity and oxygen content to prevent material agglomeration and oxidation.

In summary, the working principle of dry powder mixer is to bring powder materials into the container through rotating stirring elements, and mix the materials evenly through shearing, extrusion and impact forces. This equipment is widely used in pharmaceutical, food, chemical and other industries to meet the mixing needs of different materials.
