Understanding High Viscosity Mixing Blog Hockmeyer ...

Oct 10, 2012  One of the fascinating aspects of high-viscosity mixing is that the mixer must accurately and intensely move the product. First of all, viscous mixing systems should use laminar impellers, not turbulent impellers. Laminar impellers generally fill the entire mixing tank. In the viscous range, the formation of eddy currents is limited.
