IMPELLER TECHNOLOGY

Power of Mixing: The Impeller.

When selecting a mixing system, design and selection of the mixing impeller is key and have a decisive influence on the process engineering and mechanical properties. The purpose of the mixing impeller is important in achieving desire results through the transfer of energy provided by the motor to the product in the most efficient way in the least amount of time.

Impeller Operating Range

Mixquip can solve most mixing challenges by integrating the combined years of experience in process, mixing and impeller design with technology to deliver the scientific knowhow required for your process. Our state of the art knowledge and technology centre located in Sydney Australia uses Computational Fluid Mixing software to model the effects of different impeller designs. This means our customers can achieve optimum results – no matter what the application. We offer a variety of mixing impellers designed for sanitary and industrial mixing applications.

The Mixquip impeller design range covers almost every mixing application requirement. Maximum product yield, consistency, superior batch quality, smooth dependable operation and guaranteed process results are all hallmarks of Mixquip. Below shows Mixquip chart of mixing impellers from flow to pressure through to high-shear mixing requirements.

Low viscosity media

Axial Flow Impellers

Axial flow impellers are used with low viscosity media and are excellent for blending and suspension duties. The flow pattern has a strong axial suction and bundled discharge stream in the turbulent flow range. The outlet jet stream is deflected at the bottom and reaches the surface in the wall area of the vessel. The liquid is accelerated in the propellor zone.

AXIAL FLOW

Superflo Propeller

Mixquip Superflo propellor is a very effective low viscosity high flow mixing system with predominatly axial flow, ideally suited to higher shaft speeds. This mixing impeller design has low power number and high pumping capacity and is supplied in a range of stainless steel alloys.

AXIAL FLOW

hydrofoil_impeller_for_tank

Hydrofoil Propeller

Mixquip hydromax impeller is an axial flow based mixing system that covers both turbulent, low viscosity mixing regimes as well as positive displacement mixing in laminar, high viscosity regimes. Adjustments to the blade angle and the ratio between the tank and impeller diameters make this a very versatile impeller covering a wide range of applications.

varying range of viscosities

Radial Flow Impellers

Radial flow impellers are used with a range of viscosity media and are excellent for gas liquid mixing and dispersion duties. The flow pattern is ideal for low level mixing. The liquid is accelerated via centripetal force outwards of the propellor zone until meeting the tank wall where flow is directed both upward and down to create effective mix patterns and movement. Multiple impellers required for tank geometries greater than 1:1.

RADIAL FLOW

Radial Blade

Mixquip Radial impeller is used for high intensity mixing applications where gas dispersion or solids suspension is required. Flow patter requires multiple impellers for some tank geometry as the mixing effect lies in the shear zone of the radial outflow. Low flooding limit coupled with high power numbers makes this impeller application specific.

RADIAL FLOW

Disperser Disc

Mixquip HSD Blades impart high shear and are used for fine grinding of solids and especially difficult to disperse pigments. The high rotational speeds ensure product moves in an outward flow over blade to the teeth where solids are broken into increasingly smaller particles. Varying blade configurations are used to achieve a range of flow/shear combinations.

medium-high viscosity

Combined Axial/Radial Impellers

Combined flow impellers used both axial and radial liquid movement and are suitable for use with non -Newtonian fluids covering a wider range of apparent viscosities. The impellers create strong fluid flow patterns which are deflected at both the wall and the bottom of the tank. This combined flow action is ideal for mixing in the transitional and laminar zones.

AXIAL & RADIAL FLOW

Toro-Jet Impeller

Mixquip Torojet impeller has been designed to combine both axial and radial mixing regimes. The impeller design means that is is able to produce a flow pattern without dead zones through the entire vessel. Ideally suited to mixing non-Newtonian fluids, this impeller covers a wide range of consistency and flow behavior characteristics /rheology.

AXIAL & RADIAL FLOW

Pitched Blade Turbine

Mixquip PBT is suited to low to medium viscosity applications where axial flow is preferred and a degree of shear is beneficial to the overall process result. This design is ideal for breaking agglomerates and distributing solids within the mixing vessel.

high viscosity

Tangential Impellers

Tangential impellers are typically used with highly viscous materials and in the laminar flow range to disrupt the boundary layer adhering the vessel walls where heat transfer is required in both heating/cooling applications. Fingers or frames can be added to increase versatility of these impellers or combined with axial/radial blades as a countre rotating mixing system.

TANGENTIAL FLOW

Gate Anchor

Mixquip Gate style impeller are typically used with highly viscous materials and in the laminar flow range to disrupt the boundary layer adhering the vessel walls where heat transfer is required in both heating/cooling applications. Fingers or frames can be added to increase versatility of these impellers or combined with axial/radial blades as a countre rotating mixing system

high viscosity

High Shear Workheads

Mixquip’s high shear impellers are suitable for the blending and homogenization of liquid or similar or greatly varying viscosities, including the disintegration of solid and semi-solid materials. The high shear work heads are ideal for rapid size reduction of soluble and insoluble solids are the solution is dispersed through the mixer head at a great force causing consistent agglomerate free results.

HIGH SHEAR WORKHEADS

High Flow Stator

The high flow stator is used for a wide range of applications. This work head gives the greatest product throughput and is suitable for blending of liquids of similar of greatly varying viscosities.

HIGH SHEAR WORKHEADS

Multi-purpose Stator

The multi-purpose stator provides the solutions for disintegration of fibrous materials - used within food applications, as well as rubbers & polymers.

HIGH SHEAR WORKHEADS

High Shear Stator

This high shear stator configuration provides exceptionally high shear rates and is a perfect choice for rapid size reduction of soluble and insoluble granular solids. It is used within applications that prepare emulsions, gels and thickeners.

FREQUENTLY ASKED QUESTIONS

Have a question? We're here to help

At Mixquip, we cover a variety of mixing impeller products which are classified across 4 mixing action categories. Each impeller type converts the energy given from the motor in different ways, and knowing these types helps you select the correct impeller for your application. We have axial flow, radial flow, axial & radial flow combined, tangential flow as well as high-shear.

Axial flow pattern improves solid suspension and stratification providing top to bottom motion around the tank or mixing vessel. Radial flow pattern produces some high-shear due to the angle of the blades which is generally used for low-level mixing that take place in larger tanks where gas/liquid mixing and dispersion is required.

There are a number of different considerations that are required before selecting the best impeller choice for your application. The most important factor is viscosity as this can impact several aspects of impeller choice and design. The tank size, design and placement is also of consideration and lastly there is a choice of what material to use for the impeller which all will depend on what you are mixing and your desired results. As standard we use 316 Stainless Steel for the impellers as this is the most common and durable material, however on occasion we can specify other materials of choice. Our team are always available to help with impeller selection if you have further questions on out impeller options.
