What is the difference between common mixer
- Aug 28, 2017 -

Commonly used mixer is divided into gas and low viscosity liquid mixer, medium and high viscosity liquid and paste mixing machine, thermoplastic material mixer, powder and granular solid material mixed machinery four categories.
Gas and low viscosity liquid mixing machinery is characterized by simple structure, no rotating parts, small maintenance and low energy consumption. This kind of hybrid machine is divided into four kinds such as air stirring, pipe mixing, jet mixing and forced cyclic mixing.
A mixture of medium and high viscosity liquids and pastes, generally has the strong shearing action; thermoplastic material mixer is mainly used for thermoplastic materials (such as rubber and plastics) and additives mixing, powder, granular solid material mixing machinery for intermittent operation, but also has a mixture and grinding effect of machinery, such as wheel rolling machine.
Blending requires that all items involved in the blend be evenly distributed. The blending degree is divided into ideal mixing, random mixing and totally immiscible three states. The degree of mixing of various materials in a mixed machine depends on the proportions of the material to be mixed, the physical state and characteristics, and the type of mixing machine used and the duration of the mixing operation.

The mixing of liquids mainly depends on the mechanical stirrer, airflow and the jet of the liquid to be mixed, so as to stir the material to achieve even mixing. Agitation causes some liquid to flow, flowing liquid pushes the liquid around it, results in a circulating fluid flow in the solution, and the diffusion of the liquid between the resulting fluid is called the main convection diffusion. When the liquid flow rate is very high, there is a shearing effect on the interface between the high speed liquid flow and the low velocity liquid flow, resulting in a large number of local vortices. These eddies spread rapidly around, adding more liquid into the vortex, and the turbulent convection that was formed in small areas was called Eddy Diffusion.
The moving parts of a mechanical stirrer also have a shearing effect on the liquid during rotation, and the liquid is also subjected to shearing when it flows through the wall of the device and the various fixing members installed in the container, which will cause many local eddy currents to spread.
