for Powders & Bulk Solids



The Modulomix is a continuous mixer designed for processing fine and cohesive powders. Thanks to its high tip speeds, it is very effective at dispersing materials in a short amount of time. It can be used for low, medium, or high shear applications in the chemical, food, mineral, metal, and pharmaceutical industries.

The Modulomix horizontal paddle mixer was designed to be compact, with fast reactivity, minimal residue, and quick start-up and shutdown protocols. It produces homogeneous mixtures with little change to PSD or temperature. It is capable of extremely high heat transfer efficiency, thanks to the close contact between the material and the heated inner surface.

The Modulomix is also a modular mixer; meaning that if a mixing process consists of multiple mixing steps, which require different mixing regimes, this can easily be overcome by cascading multiple Modulomix units in series.


The Modulomix horizontal paddle mixer consists of a horizontal cylindrical process chamber in which a paddle agitator rotates. The paddles are mounted on a shaft and rotate at a fixed distance from the process chamber wall. The powder is moved back and forth in the chamber by paddles for a more efficient mixing process.

Its intensive agitation regime creates a perfect mixture with extremely short residence times, making it ideal for small quantities. Short residence times also ensure a beneficial increase in energy efficiency. Although high shear forces can be applied to the mixture, attrition effects from impact forces are limited.

The Modulomix is fast and can be adapted to varying mixing conditions thanks to its adjustable rotor speed and the design of its agitator blades. For example, mixing Mg-stearate requires a different mixing regime than drug blending. This can be solved by cascading multiple Modulomix mixers in series.

The Modulomix is also ideal for coating applications. In many cases, difficult-to-wet proteins can be instantized with the addition of less than 1% lecithin surfactant. In a similar process, calcium carbonate materials can be encapsulated or effectively rendered insoluble with a coating of less than 1% stearate powder.
