Homogeneous emulsifying machine and colloid mill are a kind of grinding materials to achieve the purpose of homogenization, high quality materials, in food, medicine, chemical and other industries have been widely used. But what are the differences between the process performance and application scope of these two kinds of equipment? Which one should we choose when choosing? The following is a detailed introduction to the difference between the homogeneous emulsifying machine and the colloid mill, hoping to bring you some help. High shear lax emulsification is the process of efficiently, rapidly and uniformly moving one or more phases (liquid, solid, gas) into another immiscible contiguous phase (usually liquid). And under normal circumstances

Homogeneous emulsifying machine and colloid mill are a kind of grinding materials to achieve the purpose of homogenization, high quality materials, in food, medicine, chemical and other industries have been widely used. But what are the differences between the process performance and application scope of these two kinds of equipment? Which one should we choose when choosing? The following is a detailed introduction to the difference between the homogeneous emulsifying machine and the colloid mill, hoping to bring you some help.
High shear lax emulsification is the process of efficiently, rapidly and uniformly moving one or more phases (liquid, solid, gas) into another immiscible contiguous phase (usually liquid). In general, the phases are immiscible with each other. When external energy is input, the two materials recombine into a homogeneous phase. Because of the high tangential speed and the weak kinetic energy brought by the high-frequency mechanical effect caused by the high-speed rotation of the rotor, the material is subjected to intense mechanical and hydraulic shearing, centrifugal kneading, liquid layer conflict, impact tearing and turbulence in the narrow gap between the stator and the rotor, forming suspension (solid/liquid), emulsion (liquid/liquid) and foam (gas/liquid). So that the immiscible solid phase, liquid phase, gas phase in the corresponding sophisticated process and the appropriate amount of additives under the common effect, instant uniform precision lax emulsification, after high frequency cycle back and forth, finally get a stable high quality products.
The colloid mill is driven by a motor through a belt drive to drive a rotating tooth (or called a rotor) and a matching fixed tooth (or called a stator) to rotate at a relatively high speed. The processed material passes through its own component or external pressure (which can be generated by a pump) Pressurized to produce a downward spiral impact force, through the gap between the fixed and rotating teeth (the gap is adjustable), it is subjected to strong shear force, conflict force, high frequency vibration and other physical effects, so that the material is effectively emulsified, scattered and destroyed, and the effect of ultra-fine destruction and emulsification of the material is reached.
From the principle point of view, they all have the effect of grinding damage, the refining effect of colloid mill is generally weaker than that of emulsifying machine, but it has strong adaptability to materials (such as high viscosity and large particles), so in many occasions, it may be used in the front of the homogenizer for high viscosity occasions. When there are more solid substances, colloid mill is often used for refinement.
To sum up, the process performance and application range of homogeneous emulsifying machine and colloid mill are very different. Homogeneous emulsifying machine is suitable for the use of high viscosity materials, while colloid mill is more used for the use of solid materials, so the grinding refinement effect of homogeneous emulsifying machine is higher than that of colloid mill.
