How to Select Stirrer Reactor

Stirrer reactor with a good selection of the best way to two conditions, one result of a reasonable choice, one choice method is simple, but these two are often difficult toconcurrently.
 
   As the liquid viscosity on the mixing state of the reactor has a great impact, so the mixing mediumviscosity according to the size selection is a basic way. Are some typical mixer withhigh and low viscosity have different scope of use reactor. With the increased viscosity of the various mixers used in order to promote the type, turbine, paddle, anchor and helical ribbon type, and so, here push the share of smaller, high-capacity liquid made ​​withlow-speed, small capacity of liquids with high speed. This selection chart of reactor is notabsolute requirement limits the use of slurry type, in fact, the use of a variety of pulptype is overlap, such as pulp-style because of its simple structure, with the baffle can improve the flow, so the low viscosity when the application of reactor was also more common.The turbo convection circulation due to its ability to turbulent diffusion and shearforces are strong, the most widely used is almost a paste type.
