The difference between mixing solid and liquid materials in a mixer
?Mixer is a mechanical device that uses mechanical force and gravity and other effects to mix two or more kinds of powder materials evenly. Can be a variety of materials with a uniform mixture, but also to increase the material contact surface area; to promote chemical reactions; but also to accelerate physical changes, such as granular for example, granular solutes into the solvent, through the role of mixing machinery can accelerate the dissolution of mixing.
Different nature of the material mixing required by the mixer is also very different, the following small introduction of solid and liquid substances for a brief description:.
For the liquidity of solid materials, mainly by the container itself rotary, or by the role of mixing moving parts installed in the container, repeatedly turning, mixing and can be mixed, while the mixing speed of solids is completely compared to the liquid material.
For the liquid usually use stirring, because the liquid mix mainly by the mixer blades, airflow and to be mixed with the liquid jet, etc., so that the material to be mixed by stirring, in order to achieve uniform mixing. Stirring causes part of the liquid flow, the flow of liquid and promote the liquid around it, the result in the container to form a circulating liquid flow, the resulting diffusion between the liquid is dominant.
Liquid viscosity is different, the mixing time is also different.
If the viscosity of the mixed liquid is not high, can not be long stirring time to reach the state of random mixing; if the viscosity is higher, it requires a longer mixing time. If the viscosity is high, the mixing time required is longer. And poor mobility and with viscous substances of solids, they are relatively troublesome to mix, it requires uninterrupted stirring and mixing. For insoluble liquids also need to give the mixer a strong shear dispersion and other forces to make the mixing effect more uniform.
The above is an introduction to the main points of solid and liquid material mixer, want to know more about some of the problems of the mixer can consult Zhengzhou Zheke Machinery, we are a professional production of food mixer, laboratory mixer, powder mixing equipment manufacturers.
