We are using a mixing system including v=40000lit,d=1m rpm=56 visc=120-800cst mixer type=pitched turbine kw=2.4. We want to reduce dissolving time by upgrading mixer diameter or rpm. Which one is the best selection for this viscous liquid? What about the other required changes followed selected upgrading? What about the amount of increasing diameter or rpm?
Have an insight or suggestion?

Re: Reducing dissolving time
23 May 2008 at 1:29pmBased on this information, viscosity and mixing intensity should be sufficient to suspend particles being dissolved. Assuming particles are in suspension, increased mixing intensity is not likely to reduce dissolving time. Mixing intensity has little effect on dissolving time, once all particles are suspended. Reduced dissolving time will probably require increased temperature or reduced particle sizes.
If you doubt these recommendations, test the effect of increased mixing intensity by reducing batch size to 35,000 liters.Same Mixer & Reduced Volume = Increased Mixing Intensity
If operating at a reduced batch size (increased mixing intensity) reduces dissolving time, then consider mixer modifications. Otherwise consider other process changes.
