Mixer classification introduced

     Commonly used mechanical mixing of gas and low viscosity liquids into the mixer , high viscosity liquids and pastes mixing machinery, thermoplastic material mixer , powder and granular solid material mixing machine four categories.
 
     Gases and low viscosity liquid mixing machine features simple structure , and no moving parts, maintenance and overhaul a small amount of low energy consumption. Such mixing machine is divided into flow mixing, mixing pipe , jet mixing and mixing four kinds of forced circulation .
 
     , The high viscosity liquid and paste mixing machine generally has a strong shearing action ; thermoplastic material is mainly used for mixing the thermoplastic material ( such as rubber and plastic ) and Tim
Mixing additives ; powdery , granular solid material mixing machine more for intermittent operation , but also the role of both mixing and grinding machine , such as wheel rolling machines. Requires all those involved in mixed materials evenly mixed . Mixing into the ideal degree of mixing , mixing and completely random mix three states. Various materials in the mixing degree of mixing machines , depending on the proportion of the material to be mixed , the physical and characteristics, and the type of machine used for mixing and mixing operation is continued for a time and other factors .
 
     Liquid mixture mainly by mechanical stirrer , air and liquid jet to be mixed , so that the material to be mixed by agitation in order to achieve uniform mixing . Agitation causes part of the liquid flow , the flowing liquid and push the surrounding liquid , resulting in the formation of circulating flow within the container , the resulting liquid is called the diffusion between the convection-diffusion body . When the agitation caused by the fluid flow rate is high , the high flow and low flow around the interface between the shearing action occurs , resulting in a large number of localized vortex. These quickly spread to the surrounding swirl , again drawn into the whirlpool of more liquid in the past, formed in a small area known as eddy diffusion convection-diffusion disorder .
 
     Mechanical stirrer, rotating the moving part will also produce shear on the liquid , the liquid flows through the device attached to the container wall and the fixing of the various components, it is also subject to shearing action , which would cause a lot of shear local eddy diffusion . Convective mixing caused by the diffusion of the body and eddy diffusion , increasing the molecular diffusion of different surface area between the liquid reduced diffusion distance , thereby reducing the diffusion time . If the viscosity of the liquid to be mixed is not high , can be stirred in a short time to reach the random mixing condition; if the viscosity is high , it would take a longer mixing time . For density , different components , immiscible liquid , the shear mixing action and a strong turbulent tear the density of the liquid into small droplets and uniformly dispersed in the main liquid. Mixing liquid flow rate must be produced than the settling velocity of the droplet . A small amount of insoluble powdery mixture of solid and liquid mechanism of different composition and density , immiscible liquid mixture the same mechanism , but mixing powdery solid particle size can not be changed . If you can not make solid particles before mixing settling velocity is less than the flow velocity of liquid , regardless of the mixing method are not form a uniform suspension .
 
     Different mixing paste mainly to the material to be mixed and to be pressed repeatedly split , rolling , extrusion and other movements generated a strong shearing action , followed by repeated combined , kneaded , and finally to achieve the required degree of mixing . This hybrid is difficult to achieve the desired mix , only to reach a random mix . Powdery solid with a small amount of the liquid mixture is paste, paste the mixing mechanism and the mechanism of the same material mixing . The thermoplastic material of different thermoplastic material and mixed with a small amount of powdered solid , the need to rely on strong shearing , rubbing and kneading again , in order to achieve a random mix .
 
     Good mobility particulate solids container itself depends mainly on the rotation of the container or by moving parts mounted on the role of repeatedly turning , blending and can be mixed with the gas flow generating such materials can also be used to achieve mixed convection or turbulence . Solid particles is not easy to produce eddy convection or turbulence , mixing speeds well below the liquid mixture , the degree of mixing generally only reach a random mix . Illiquid , each occurrence of adhesion of the particles or powder solid , is often required with mechanical turning and pressing , rolling and other mechanical mixing action .
