Powder mixing and accompanying procedures

The powder mixing process is coupled with a wide variety of accompanying operations. This is visible when individual particles of the mix are examined microscopically. However, the accompanying operations are described differently in the sectors, although the same physical impact takes place. There are many dozens of different mixing processes. Many of these are customized for specific industries. amixon® manufactures a wide range of precision powder mixers that are used in virtually every industry.



amixon® manufactures a unique portfolio of various precision mixers/vacuum mixing dryers and synthesis reactors. All apparatus types are available for testing. Across all industries, our mixer types achieve peak performances - worldwide!

Basic process powder mixing

Powder mixing is a basic operation that has been practiced since time immemorial. Powder mixing tends to be onsidered a trivial procedure. However, if you take a closer look, you can see that many accompanying effects take place simultaneously and even in opposite directions during powder mixing, such as deagglomeration wetting, coating, segregation, build-up granulation (agglomeration), dehumidification (drying). A chemical reaction or a crystallization can also take place.

The process objectives on the info cube have different significance for the respective industries: In the pharmaceutical industry, active ingredient synthesis and vacuum drying are of great importance. Trituration and agglomeration are important in solid galenics. In the food industry, flexibility and hygiene are important, but in particular, the mixing process should be performed in a specifically gentle manner. In the fine chemistry and plastics industry, dead-space-free synthesis reaction is important. Nanoparticles often serve as coating substances and must completely coat the particles of the active ingredient.

Some procedures are batch-based, others are continuous. However, all mixer types of the amixon® manufacturing range are applied across all industries.




KoneSlid® Blender Model KS. This type of cone blender has special properties with regard to a) minimum energy input and b) complete emptying: Technically ideal mixing qualities are achieved within a few seconds. The particles are not damaged or altered in the process. After completion of the mixing process, the mixing tool is at rest. Within a few seconds, free-flowing materials flow out completely.

Process parameters and preparation steps

At the end of a mixing process, the result should be a homogeneous powder mixture that meets the expectations. With the help of the process parameters named below, the targeted processing step can be navigated:

  • Material composition/recipe
  • promoting or avoiding particulate interactions (chemical, physical)
  • particle sizes
  • temperature
  • presence of liquid substances
  • Method of liquid injection
  • pressure level
  • Type of flow generation
  • Sequence and timing for the addition of ingredients
  • turbulence intensity of mixing
  • Mixing time
  • many more


Powder mixing and accompanying processes are important topics in the production of high-quality pharmaceuticals, nutrients, chemical agents and high-performance materials. With trials in the test center of amixon GmbH, Paderborn, we make valuable contributions to solving your problems.
