Many of our customers enquire about the purchase of a disperser when they already have a blender. The purpose of both devices is very similar. Let’s consider the cases when it is better to use a blender and a homogenizer.
The main difference is that the blender stirs the raw material and the disperser mixes and evenly distributes the components achieving uniformity throughout the mixture. Theoretically, it is possible to obtain emulsion or suspension using a high speed mixer. But there is no guarantee in stability of the mixture, because it contains large particles. After a short time the mixture will inevitably separate. The disperser can provide achieve particle size of 1 micron or even less, thereby ensuring stability and longevity of the mixture.
Some confusion may also occur when choosing between a disperser and a homogenizer. As mentioned above, the main function of a disperser is grinding of substances. A homogenizer is used for mixing solid and liquid components to uniform consistent mixtures. At the same time, the term “homogenization” is also applicable in case of substances which under normal conditions are immiscible or poorly miscible with each other. A well known homogenizer a KLM colloid mill by GlobeCore, operating on the principle of “wet milling”.
In a colloid mill, the centrifugal force and high relative speed between the rotating rotor and a stationary stator turn liquid and semi-liquid materials into uniform, finely dispersed and homogeneous mixtures. The KLM unit simultaneously disperses and homogenizes the processed substances.
The equipment can be used both as an independent unit and as an integral part of a production line. The integration process is easy and simple.
