amixon® conical mixer 1500 - universally usable powder mixer

In short, the AM 1500 conical mixer is an all-rounder for small and large batches and ideal mixing qualities. With a maximum batch volume of 1,500 litres, the gross volume is approx. 33 % larger than other mixers. Hundreds of mixing companies have confirmed on the basis of more than 1,000 recipes that this conical mixer mixes quickly and ideally and accurately, regardless of the powder consistency: different particle sizes, different bulk densities, finely dispersed, lumpy, moist, dry, wet, suspended, etc.

What is the explanation for this great flexibility/ variety of uses? We dedicate ourselves to this answer, taking into account frequently asked questions from our customers:


Sometimes the operator wants to mix not only large but also very small batches with one and the same mixer. Then, for example, the filling level is only 10 %. But the mixing quality should be ideally good. Which type of powder mixer is recommended then?

In your case, we would recommend the AM conical mixer. "Highest mixing quality at different filling levels" is the characteristic that justifies the existence of this conical mixer. Hardly any other mixer design can be used when the filling level is only 5 % or 10 %. Maximum flexibility is the essence of the amixon® conical mixer.


Most of our mixing orders include the specification to use a high-speed agitator to ensure that any existing lumps or agglomerates are deagglomerated. Does this requirement reduce the application range of the mixer?

  • if the mixed materials are to be deagglomerated with high-speed agitators at a low filling level?
  • when highly viscous liquids have to be distributed micro-fine in the powder at a low filling degree?


The size reduction of lumps and agglomerates is often an important accompanying process. Only when the goods are deagglomerated can they be ideally distributed. For this reason, high-speed rotating agitators (centre bottom) support the mixing work.

Such mixing tools have various names. For example, whirler, chopper, cutter head, cutting rotor, HighShearBlades, homogeniser or mixing accelerator.

It is interesting to note, however, that deagglomeration in the conical mixer is already effective at low filling levels. Good efficiency is always achieved when the swirler is covered by the powder. Cone mixers can meet this requirement particularly well.


The minimum filling level is an almost constant figure

Please have a look at the sketch above. Simplified, you see conical mixers of different sizes. The smallest is sketched in red, the largest in yellow. What they all have in common is the constant position of the swirler. So you can see that the minimum filling level remains the same, even if the conical mixer itself is chosen to be larger. This is the reason why we cannot give the minimum level in % of the maximum volume when an agitator is installed. The range of use of conical mixers increases with the size selected.

amixon® recommends: To define a minimum filling level of your future mixer, mixing tests should be scheduled at the amixon® test center. Based on the tests, 4 important questions can be answered:

  •     What type of agitator has the best effect?
  •     Which frequency of rotation has the best effect?
  •     What drive power should be used?
  •     How many centimeters of mixing good should be at least above the whirler?


Explanation: Other names for agitators are e.g. shear blade, cutting rotor, chopper, mixing accelerator, disagglomerator, chopper, cutting head, mixing turbine, hexler, ...

Are there any other reasons to choose a conical mixer from amixon®?

Yes, indeed. There are other valid reasons to choose an amixon® conical mixer.

  • excellent discharge of residues when the mixing goods are sufficiently free-flowing.
  • excellent accessibility with the aid of one or more hygienically designed inspection doors.
  • highest hygienic standards.
  • Very easy cleaning; whether dry, wet or damp, manual or automatic.
  • particularly stable construction and a long service life
  • amixon® mixers are permanently gas-tight. This applies equally to dust and water.
  • amixon® provides excellent service worldwide.


If it is claimed that one and the same amixon® mixer can be used for different types of powder, why does it still make sense to arrange mixing trials at amixon®?

Before making a purchase decision, we generally advise mixing trials in our test-centre. The particle size distribution and the appearance, flowability and colouring of the powders are strongly influenced by the agitator design and the operating mode.

In addition, mixing trials with a foreign mixing system are always accompanied by new impulses and perceptions. A visit to amixon® is sure to provide you with a great gain in knowledge.

Minimum filling levels can be defined for various mixer sizes: for gentle homogenisation and for deagglomerating powder preparation.
