The Ross PowerMix is ideally suited for the dispersion of minor ingredients into a major carrier. The unit includes two separate agitation systems within one mixer. A powerful planetary blade revolves in combination with a separate high-speed dispersion blade. Both revolve on their own axes as well as on a common axis, and each can have its speed varied independently of the other. This combination allows a user to fine tune the mixer to meet specific process needs and the shear rates required to optimize processes. The PowerMix is used for high-viscosity vacuum mixing and dispersion, as well as the dispersion of minor liquid or powder ingredients into powder mixes. The PowerMix is available in many sizes, from a ½ gallon lab unit through a 750-gal production model. Many optional features are supplied, including: materials of construction; vacuum and pressure designs; jackets to heat or cool; wall scrapers; sanitary construction; and more. Test and rental machines are available from Ross.
