Vacuum homogenization emulsifying machine plays a great role in the mixing system of various industries. This feature is very obvious in the aspects of solid-liquid integration, water-oil emulsification, homogeneous dispersion, grinding and shearing. The role of the vacuum homogenizing emulsifier has two aspects, one is emulsification, and the other is dispersion. What is dispersion? Due to the shearing function of the vacuum homogenizing emulsifier of Guangzhou Union machinery and equipment, the crushing and collision of the powder particles in the water liquid is finally reduced to the desired particle size, so that the solid is completely mixed into the water liquid, thus becoming a relatively stable suspension, this workflow is called "dispersion". As with emulsifiers, add

Vacuum homogenization emulsifying machine plays a great role in the mixing system of various industries. This feature is very obvious in the aspects of solid-liquid integration, water-oil emulsification, homogeneous dispersion, grinding and shearing.
The role of the vacuum homogenizing emulsifier has two aspects, one is emulsification, and the other is dispersion. What is dispersion? Due to the shearing function of the vacuum homogenizing emulsifier of Guangzhou Union machinery and equipment, the crushing and collision of the powder particles in the water liquid is finally reduced to the desired particle size, so that the solid is completely mixed into the water liquid, thus becoming a relatively stable suspension, this workflow is called "dispersion". As with the emulsifiers, the stability of the suspension is greatly increased after the addition of the dispersing agent. If some solid matter can be completely dissolved by the liquid together with the mixing of the liquid over a certain period of time, the fine particles formed by the shearing collision will be dissolved by the liquid very quickly.
Everyone is used to using high-pressure homogenizer to get fine particles, refinement and homogenization are the same meaning. Emulsification machine acts on the process of material refinement and full mixing, also known as "homogenization. Therefore, we can also call the emulsifying machine a homogenizer. In order to distinguish the categories, it is usually called high-shear or high-speed homogenizer. Therefore, the emulsifying machine can be called a high-shear dispersing emulsifying machine, a high-shear emulsifying machine, a high-shear homogenizing dispersing emulsifying machine, a high-shear homogenizing machine, a high-shear homogenizing emulsifying machine, and the like.
The efficiency of the shearing action of the emulsifying machine directly affects the final fineness. After analysis by the professional engineers of Guangzhou Union Machinery, it is related to the sharpness of the blade, the hardness, the clearance of the rotating stator, the relative movement speed of the two cutting edges and the particle size allowed to pass. Generally speaking, the blade sharpness, hardness, rotating stator clearance and the particle size allowed to pass are generally shaped or not ready to change, then the relative movement speed of the blade is the biggest influencing factor. The manifestation of this situation is the circumferential linear velocity of the rotor. If the linear velocity is high, the density of cutting or collision of the radial flow fluid is high, so the refinement effect is strong, and vice versa. However, the line speed is not the greater the better, when reaching a very high value, there is a tendency to block the flow, so the flow becomes smaller, and the heat is very high, some materials in turn will gather, resulting in the final effect can not reach the target value.
Is the stirring speed we usually say shear speed? Senior high school knowledge of physics teaches us that one is angular velocity and the other is linear velocity. Shear speed naturally refers to linear speed, which is equal to angular speed multiplied by π multiplied by diameter. This is why the rotating speed of emulsifying machines used in industrial production generally only reaches 3000rpm or 1500rpm, while the rotating speed of laboratory emulsifying machines is as high as 10000rpm or even 280000rpm. That is to say, taking into account the influence of diameter, the shearing linear speed of the two machines tends to be the same, and the final effect is almost the same.
On the other hand, the characteristic of laboratory tests is that the dosage is not much. Therefore, if the size of the rotating stator is suitable for the corresponding small amount, the diameter must be reduced. In order to supplement the negative influence of the small diameter on the linear velocity, the angular velocity of the rotating must be increased, thus reaching the "high rotation speed" of the experimental instrument. Therefore, the rotating speed of the emulsifying machine should be analyzed and applied in combination with the actual processing capacity. However, considering the existing processing level and the economic effect of production, the rotating speed of a 2-pole motor below 18.5KW is generally 3000rpm, while 22KW to 55KW is generally 1500rpm of a 4-pole motor, and 1000rpm of a 6-pole motor can be considered above 75KW.
