| Planetary Mixer Blade Configurations: Selection of mixing and dispersing tools and different butterfly and toothed disperser blades allows optimization of the machine for specific processes |
NETZSCH offers two different Planetary Mixers. The PMH consists of a high speed butterfly shaft and low speed axial flow agitator. The PML consists of two low speed axial flow agitators. Both systems rotate eccentrically in the process vessel. The two systems rotating in the vessel create a rotating shear zone, ensuring superb dispersion results. The high and low speed systems have separate drives, allowing precise control of the mixing and dispersing process.
The two independently operating mixing systems are hydrostatic variable speed drives. This system guarantees low energy consumption with optimal dispersion quality in a short period of time. The low energy consumption makes the system ideal for temperature-sensitive products.
A tank wall scraping blade eliminates dead zones at the tank wall and ensures thorough movement and mixing of the product. The scraping blade enhances the heat transfer from the vessel cooling or heating jacket by continuously sweeping material from the heat transfer surface.
Optional equipment, such as spray balls and temperature probes, can be mounted to the planetary system, increasing cleaning efficiency and temperature control.
The PMH Mixer (high energy input) (Config. 1) performs fine disintegration and dispersion. The PMH is ideal for mixing and dispersing products that increase in viscosity during the process cycle (eg, feeding of solids, chemical reactions). The PMH develops the high shear forces required for difficult to wet dispersions and/or that have poor flow characteristics. This gives the machine the ability to process formulations up to over 20,000 poise. Alternately, the PMH can be supplied with a high speed dissolver blade as shown (Config. 2).

The PML Mixer (low speed) (Config. 3) with axial flow agitators performs kneading or low energy dispersion. The PML is ideal for applications where the viscosity is constant, only low shear forces are necessary or materials are temperature-sensitive. The PML offers excellent results on products up to 6,000 poise or less.
