The PowerMix Model PDM-10 from Charles R. Ross & Son Co., Hauppauge, N.Y. reportedly combines high-speed dispersion with planetary stirring action. This is said to provide the advantage of imparting high shear to tough-to-mix applications with low flowability. Pictured are two PowerMix machines with interchangeable mix vessels. Beyond a traditional kneading action, the mixing mechanism of this proprietary planetary design is said to be ideal for heavy pastes and slurry-like applications involving a considerable amount of powders that need to be wetted out and dispersed uniformly.

These 10-gal models feature an additional sawtooth blade on each disperser shaft, doubling the shear input capacity of the mixer. A rectangular stirrer orbits the vessel, effectively exposing the entire batch contents to the shearing action of the dispersers. For more viscous applications prone to climbing up the stirrer, patented high-viscosity blades are available and offer a helical curvature which pushes product forward and downward. Fully automated PLC recipe controls and data acquisition systems are available for optimal mixing results.
