An essential component of industrial equipment mixing solutions is the emulsifying mixer. This is particularly true in shear grinding, emulsification of oil-water, dispersion homogenization, and solid-liquid and liquid-liquid mixing. Its ability to carry out emulsification is why it has the name emulsifier. An emulsion, classified as either water-in-oil or oil-in-water, is created by thoroughly mixing the oil-water two-phase media.
There are a pair of conditions for emulsification: The water-oil phase comes first, followed by vigorous mechanical cutting and dispersing. Fluid medium particles are chopped and shattered into small fragments all at once. They were mixed together to form an emulsion. The second one, using charge and intermolecular interactions, acts as an agent bridge between oil and water molecules, making it a perfect emulsifier. The stability of the oil-water emulsion depends on how long we need to keep it.
These days, emulsification is only one of several uses for the emulsifying machine. The distinctive shearing action of the material eventually reduces the pulverizing effect of the granules in the liquid to the necessary particle size, allowing for the complete mixing of the solid and liquid components. Also, dispersion—the formation of a suspension—occurs. Similar to how an emulsifier may improve the suspension’s stability, a dispersion agent can do the same.
Liquids dissolve solids when they come into touch with them over time. The shearing impact creates tiny particles, which the liquid may dissolve more rapidly with the increased particular surface area.
A high-pressure homogenizer becomes necessary when techniques like compression and high-pressure instant jet impact become the norm for getting small particles. Fine and homogenous are the same things. After introducing the emulsifier, the material refines, and full mixing also produces a homogenous end product. Thus, another name for the emulsifying machine is a homogenizer. While this emulsifying machine is often known as a high-shear dispersing emulsifier, it is also known as a high-shear homogenizer or simply an emulsifier.
Emulsifying Mixer Strength
Ultimately, the fineness depends on how strong the shearing action of the emulsifying mixer is. According to the results, the two most important factors are the hardness and sharpness of the blade. The distance between the rotor and stator, the relative speeds of the two blades, and the maximum particle size that the blade’s hardness and sharpness can accommodate. The most important component is the corresponding knife edge speed. This is because the rotor-stator gap and permissible particle size will either not vary or have been set rigidly. As the stator is motionless, this can be described as the rotor’s circular speed.
Does A Faster Emulsifying Mixer Work Better?
Because of the high shearing or impacting density on the radially moving fluid, fast line speed provides a significant refining effect. The line speed needs to be more quick, however. Its tendency to hinder the flow is evident at very high levels, much as how a formidable fighter could twist the blade to deflect an incoming arrow. This results in extremely low flow, very high treated material temperature, and some material accumulation, all of which have negative effects.
Is the shear speed the one we often use when talking about stirring? Two components of speed—angular velocity and linear velocity—are well-known. Linear velocity = angular velocity x diameter x n is the formula for shear rate, which is the linear velocity. In industrial production, emulsifying machines typically operate at speeds of 3000 rpm or 1500 rpm @>50Hz, while lab emulsifiers can reach speeds of 10,000 rpm or 280000 rpm, considering the diameter factor. This allows for a close relationship between the two shear line speeds, producing a close final effect.
Looking at it from a different angle, the laboratory is defined by limited testing. As a result, the spinning stator’s physical dimensions—its diameter and length—need to be kept to a minimum. The adverse effect of the tiny diameter on the line speed can only be overcome by making improvements. Therefore, the demonstration instrument’s high rotational speed is formed by the rotor’s angular velocity.
All of this points to the fact that production capacity should dictate the emulsifying machine’s rotating speed or angular velocity. Present processing levels and manufacturing economies often use 4-pole motors from 22 to 55 kW, 6-pole motors beyond 75 kW, and 2-pole motors below 22 KW.
