In recent years, the requirements for mixing systems in industrial applications have increased steadily. The design of the impellers, the selection of a suitable mixing system, as well as the arrangement of the individual components on the agitator have a decisive influence on the process engineering and mechanical properties. This not only applies to the agitators but also the reactors and their components. The comprehensive optimization of conventional impellers with industry-specific aspects was the basis for the development of the EKATO impeller family which is continually setting new standards in the field of mixing technology.
HELICAL RIBBON IMPELLERS The helical ribbon impeller is suitable for homogenizing highly viscous media. It consists of a band-shaped helix which is fixed to the shaft by cross-bars. In contrast to the propeller, the axial flow is not caused by pressure differences, but by a displacement effect in the laminar flow regime. One disadvantage of the helical ribbon impeller is the mandatory use of crosspieces for stabilization.
These prevent the installation of baffles, dip tubes, etc. Which may be beneficial or necessary in many practical applications. With a diameter ratio of 0.9 to 0.99, the helical ribbon impeller is a close to the wall operating impeller.
FLAT BLADE DISC TURBINES A representative of the radially pumping impellers commonly used is the flat blade disc turbine. Several (usually six) vertical rectangular blades are arranged symmetrically along the circumference on a horizontally arranged carrier disc.
The the flat blade disc turbine is mainly used for gassed applications. In this case, the disadvantages of this impeller are a relatively low flooding limit as well as a high power decrease. An extension to further mixing tasks is only possible under certain conditions.
With this impeller, the actual mixing effect predominantly occurs in the shear zone of the radial outflow. DISSOLVER DISCS Further typical radial pumping impellers are dissolver discs, also called disperser discs.
The EKATO DISSOLVER, consists of a carrier disc on which tooth-shaped elements are arranged vertically on the disc along the circumference. Dissolver discs are suitable for mixing tasks requiring high shear gradients (e.g. Emulsifying, crushing of solids and wet grinding) and are often used in combination with other impellers as a mixing system. The required high local shear forces are thereby achieved by high circumferential speeds in a small volume. For highly viscous media, an additional axial flow impeller ensures sufficient circulation in the vessel. RETREAT CURVE IMPELLERS The retreat curve impeller is a relatively fast-running impeller with (usually) three blades bent backwards in the direction of flow.
