The patented PowerMix is ideally suited for the mixing and dispersion of minor ingredients into a major carrier. It includes two separate agitation systems within one mixer. A planetary blade revolves in combination with a separate high speed dispersion blade. Each revolves on its own axis as well as on a common axis and the speed of each can be varied independent of the other. This combination allows a user to fine tune the mixer to meet his specific process needs and the shear rates that are required to optimize his process.
