Drum hoop blender for mixing solid materials.


Drum Hoop Blender

The RM-6 Drum Hoop Blender is ideal for mixing solid materials such as powders and granules prior to encapsulation or tableting. It can also be used for mixing of wetted powders. It is suitable for R&D and for industrial use as well as for small batch production for various applications in the pharmaceutical, chemical and food industries.

Construction Structure

The diagonal placement of the plexiglas drum within the hoop introduces a uniform 3D displacement of the processed materials when the hoop rolls on the rotating tracks and causes hence a “3D-Tumbling” pattern of mixing. The rolling track is joined directly to the UAM Universal Motor Drive. The speed is stepless adjustable due to the advanced electronic speed control system of the UAM Universal Motor Drive.

Filling the Drum

The plexiglas drum can be filled with approximately 40% of its total height with solid materials. The particle size and properties of the material play a key role in estimating the filling level. In the case of liquids, the filling level can reach up to 80% of the drum height. After filling, the drum has to be closed and sealed using two clamp latches.
