In almost all bulk solids processing industries such as the chemical, food and pharmaceutical industries, individual powder mixtures for different tasks are produced by powder mixers or powder blenders. The mixing goods can be powdery, finely dispersed, agglomerated, pelleted, dry, moist or suspended. Powder mixers are used wherever heterogeneous mixtures of substances have to be mixed according to a specific formulation. Generally, two types of powder mixers can be distinguished according to their basic structure:
In contrast to the horizontal mixer, the vertical powder mixer has a screw-band mixing tool, which is usually mounted only above the mixing chamber.
The Powder Mixer KS offers great advantages in terms of hygiene. In addition, this design is also considered especially wear resistant. Powdery goods are often abrasive and sometimes adherent. In individual cases, liquid additives should be added to the powders, depending on the recipe.
EM Powder Mixer - If a powder is moistened, it often changes its properties such as flow ability, bulk density, porosity or colour, tendency to adhesions, segregation and agglomeration. The method of wetting in the powder mixer might also affect the properties of the powder.
The sinking behaviour, solubility and dispersion
properties of a mixture can be significantly influenced. Examples are
dried instant soups, iced tea or cappuccino powder, instant sauces,
instant desserts, cereals and baby food.
Finely dispersed powders as well as larger particles can be coated
directly in the powder mixer, for example by adding a liquid.
Agglomerates of powders or pellets can also be produced.
that, some vertical powder mixers can also be used for the mixing of
high viscosity liquids, suspensions and dough. Powder mixers and powder
blenders can also perform further tasks, such as those of a vacuum mixer
dryer. The wet powder can be heated by contact with the tempered mixing
This way, the dispersed liquid in the powder
evaporates. By applying vacuum, the boiling point is reduced. This
speeds the drying process up.
Powder products can be changed or sterilized by being subjected to
steam. Powdery substances are heated and material properties are changed
by applying pressure or vacuum.
This way, the blender
functions as a reactor (synthetic chemistry).
In many manufacturing processes in which powders are processed, amixon®
powder mixers and powder blenders make a value-increasing share. They
also bear the ability to empty themselves to a particularly high degree.
Often the formulation compositions are heterogeneous and can hardly be
analysed in a state of powdery bulk material.
amixon® can carry out practical tests with many test mixers available. For this purpose amixon® would like to invite you to our test centres in Paderborn, Memphis/USA, Osaka/Japan, Bangkok/Thailand, Tianjin/China or Satara/India.
