If these constraints are unacceptablĬlick the following links for more information about liquid blending and solids suspension mixing applications. However, even when multiple agitator impellers are used, it is generally impractical to suspend solids higher than about 1.4 times the tank diameter, and it is nearly impossible to suspend them more than twice the tank diameter in a conventional tank. It is important to recognize that solids can easily be suspended to a height of about 85% of the tank diameter with a single agitator impeller. Angleoffset mixers are generally restricted to relatively small volumes although we have used them successfully in 25,000 gallon tanks. Straightvertical offset mixers in unbaffled tanks leave a significant heal of solids in one sector of the tank floor. A center mounted industrial mixer in an unbaffled tank does not effectively suspend solids. It must either be baffled with the industrial mixer on center or the mixer can be angleoffset mounted. The optimum tank design for solids suspension mixing applications is round and has an aspect ratio of about 1:1. When you are blending liquids of significant viscosity, the flow is laminar (i.e., not turbulent). Odd shaped mixing tanks often require more than one industrial mixer as do very shallow pits and sumps. As an example, for a typical miscible liquid blending application, you cant place one industrial mixer close to the end of a long, horizontal cylindrical mixing tank (Figure 1) and expect to effectively agitate the vessel contents. Although you can use just about any tank design for blending waterlike liquids, the tank geometry determines the placement and number of industrial mixer(s) for effectiveblending. It can be round, square, rectangular, horizontal cylindrical or even irregularly shaped. It can be short and squatty or tall and skinny. Almost any mixing tank configuration is allowed. When the viscosities are waterlike (e.g., whiskey, beer, wine, window cleaner, mouthwash), the flow is turbulent. Viscosity is the most critical factor in tank design for liquid blending.
