Mixing equipment is the use of mechanical force and gravity, etc. , will be two or more materials uniform mixing machinery.
Mixing equipment is widely used in various industrial and daily life.
Mixing equipment can be a variety of materials to fit into a uniform mixture, such as cement, sand and gravel mixed with water into concrete wet material, etc. ;
Also can increase the material contact surface area to promote chemical reaction;
Can also accelerate the physical changes, such as granular solute in the solvent, the role of the v-shaped
mixer can accelerate sugar.
Commonly used mixing equipment is divided into gas and low viscosity fluid mixer, high viscosity fluid and paste mixing machinery, thermoplastic material mixing machine, powder and granular solid material mixing machinery four categories.
Gas and the characteristics of low viscosity liquid mixing machine is simple in structure, and has no moving parts, less maintenance, low energy consumption.
This kind of machine is divided into air mixing, pipes, mix, four jet mixing and forced circulation, etc.
, a mixture of high viscosity fluid and paste in the machinery, generally has strong shearing action;
Thermoplastic material mixing machine is mainly used for thermoplastic material (
Such as rubber and plastic)
Mixed with additives;
Powder, granular solid materials mixing machinery for intermittent operation, including both mechanical mixing and grinding effect, such as wheel roller, etc.
Mixed requires all participate in the mixed material evenly distributed.
The extent of the divided into mixing, random mix and completely mixed three states.
Kinds of material in the mixed mechanical mixing extent, depend on the proportion of mixed material, physical state and features, as well as the type of mixing machinery used and the duration of the mixed operation and other factors.
A mixture of liquid mainly by mechanical agitator, airflow and treat mixed liquid jet, subject to mix material to churn, mixing in order to achieve.
Agitation caused part of the liquid flow, the flow of liquid and to promote the surrounding liquid, results in solution in form of circulation flow, the resulting liquid diffusion as the main body between the convective diffusion.
When agitation caused by the liquid flow rate is very high, around the high-speed flow with low speed flow appears on the interface between the shearing action, resulting in a large number of local vortex.
The vortex is rapidly spreading around, and more of the liquid in vortex, convection diffusion on a small scale formation of the disorder called eddy diffusion.
Mechanical agitator in the moving parts in rotating when also can produce shearing action of liquid, the liquid flows to the wall and installed in the container of various fixed member, also want to get shearing action, the shearing action can cause many local eddy diffusion.
Mixing caused by the body of the convection diffusion and eddy diffusion, increase the surface area of the molecular diffusion between the different liquid reduces the diffusion distance, thereby to shorten the time of the molecular diffusion.
If need to mix the viscosity of the liquid is not high, can be achieved in short mixing time randomly mixed state;
If the viscosity is higher, need longer mixing time.
The miscibility of liquid density, different components, each other, and the effects of the shear mixing and strong turbulent to tear into small droplets and dense liquid which was dispersed evenly into the liquid to the master.
Stir the liquid flow rate must be greater than the settling velocity of the droplet.
A small amount of insoluble solid and liquid mixing mechanism, composition and density is different, each phase of soluble liquid mixing mechanism are the same, just can't change the size of the solid.
If hybrid solid particles can't make it before settling velocity less than the flow of liquid, no matter what way to stir not form homogeneous slurry.
In the past few decades,
cosmetic machinery manufacturers production has increased because of the use of chemical reactor.
