What Is The Distribution Range Of Colloid Grinding Fineness?

The fineness of the colloid mill mainly depends on its structural design, rotation speed and material properties. Generally speaking, the fineness of the material treated by the colloid mill can reach the micron level or even the nanometer level. Specifically, for most materials, the colloid mill can achieve a fineness of D90 (90% of the particle diameter) between 2-50 microns. This range makes the colloid mill widely used in food, chemical, pharmaceutical and other fields.
It is worth noting that the fineness distribution range of the colloid mill is not a fixed value, but is affected by many factors. For example, different materials may produce different fineness distributions due to differences in material properties under the same colloid mill treatment. In addition, the model, rotation speed and operating conditions of the colloid mill will also affect the fineness distribution.

The mesh number is a unit used to measure the particle size of the material. The larger the mesh number, the finer the particle size of the material. The particle size range of 50-100 mesh is relatively coarse and suitable for some application scenarios that do not require high particle size. For example, in the pharmaceutical industry, the initial crushing of some traditional Chinese medicines or chemical raw materials can be completed using a 50-100 mesh grinder.
However, if a finer particle size is required, such as micron or even nanometer, then a colloid mill will be a better choice. By comparison, it can be seen that the colloid mill and the 50-100 mesh grinder have obvious differences and complementarities in particle size processing.
