How does Rotamix work?
The Rotamix system incorporates several basic principles of physics and hydraulics, including uniform field of flow, vortical field of flow, induced flow and surface contact. Combined together, this unique mixing concept optimises solids contact due to the homogenous state.
Mixing flows are distributed through each nozzle simultaneously, which allows for very rapid development of rotation, maximising solids contact to optimise system performance. The Rotamix system is specifically developed to eliminate the “tea cup” phenomenon – a problem with most rotational mixing methods. Rotamix evenly distributes flow to both inner and outer portions of the tank, preventing pressure zones from developing and prohibiting solids from migrating towards the center of the tank. Mixing energy is distributed across the tank center floor, raising and drafting solids outwards towards the periphery, where in a circular tank, the greatest degree of natural rotational speed occurs.
