Planetary mixer HMDV series

One shaft mixer double column The HMDV MOLTENI MIXERS introduce a new working system in the mixing of high viscosity products (up to 6.000.000 cps). With the new HMDV technology, the rotation and revolution motions of the standard planetary mixing blades are replaced by the rotation and the vertical oscillation of a single shaft with a large mixing impeller. Thanks to this solution it is possible to involve all the product contained into the mixing tank with only few vertical alternative movements of the impeller. The mixer shaft transfers the rotation movement to the impeller which has the same diameter of the vessel. Therefore the impeller works also as side scraper. This system assures a perfect homogenization and a much faster powder mixing than the traditional systems though the product, due to a high viscosity, does not have a regular flow. The whole mixing process can be carried out under vacuum and the impeller goes out from the product, keeping always a vacuum condition into the mixing vessel. This allows at the end of the process to have: A flat product surface inside the tank No air at all into the product during the handling of the vessel inside the production facilities The NEW MIXERS ARE AVAILABLE IN TWO MODELS: EMDV 1000 SV with electromechanical drive HMDV 1000 SV with oleo-dynamic drive Both models are controlled by a PLC system and, upon need, by a PC, for a complete automatic integration of the HMDV / EMDV into complete plants. It is also available the HMDV-S / EMDV-S model (Extruder Mixer), with capacities up to 2500 litres, which enables the product discharge while the machine cover is closed and with vacuum conditions inside the mixing vessel.
