Mixing Propellers & Blades
We provide our customers with a complete solution to all mixing problems with our special team. Standard propellers and blades are available in a wide range of products from ¼ “to 10” diameter, four blades with axial blades, radial blades with special turbines and impellers.
We provided more than 30 years of service with specific solutions in propeller blades which are designed for various processes. With our type of specially designed propeller blades, better mixing is obtained and the spaces in the container which blocks the product from moving are removed.
Do not hesitate to contact us in order to benefit from our knowledge and experience in mixture.
1- Three-blade marine propeller
The marine propeller, the first type of axial propeller used in mixing boilers, provides good homogenization. The maximum recommended propeller diameter is 6 “/ 150 mm for this type which is used up to 5 HP power for good results. General application areas are determined as: a maximum of 1,750 rpm for speed and a maximum boiler volume of 2,000 liters. The permissible viscosity limit is 5000 cP (used for low to medium viscosity products) and the lowest Reynolds number is NRe 200. Marine propellers are used for axial flows where pump effect is required. The liquid is carried away from the propeller surface without any cavitation occurring related to its special design.
2- Hydrofoil Propeller
The hydrofoil blade, which is a highly efficient propeller, has competitive power amongst many other mixing types. It is used in all speed ranges for heat transfer, blending, solid suspension. Ideal measurement is done by keeping the diameter of the boiler between 0,4 and 0,6, which will be selected in D / T ratio. The NRe limit is set to ≈200.
3- Six Blade Disc Propeller
The first type known is the Rushton Turbine propeller type, which is still the first type used in some special applications. The design creates the necessary tension with the power it creates and eliminates the emulsion. Gas-liquid dispersions, liquid-liquid dispersions and chemical reactions requiring rapid formation are used in application areas, in small vessels and at low gas ratios. NRe limit ≈ 5
5- Four Blade Propeller (90 ºC)
Such propellers are used to provide a mixture for evacuating the boiler. In practice it is suitable for low stability situations. In this propeller type, which we also call the flat blade type, a radial flow is provided. The yield can be obtained if the mixing tank is low in volume. NRe limit ≈ 20
6- Saw Type Mixer
In saw-blend mixers, the main effect of the propeller is to provide extra tension from the mixture. Commonly, in liquid-liquid emulsion and in intense gas-liquid (foam control) dispersion, solid (powder) -mixture dispersions are used. Often used with a larger diameter axial impeller, this type of saw is located in the upper zone of the shaft and mixes the product from the other propeller. NRe limit ≈ 10
7- Six Knife Concave Propeller
This type of propeller uses 6 half-tubular blades. This type of mixture, the actual application of which is gas dispersion, is suitable for large volume boilers. Fermantors are used at high gas flow rates up to 300-350 tons. Compared to a six-bladed disk impeller, the concave propeller makes it possible to flow twice as much gas under the same conditions, and the liquid rise from the motion drops to 30% from 50%.
8- Rotor-Stator Mixer
R & S Mixers are the type of mixers used for dispersing, emulsifying, suspending and dissolving conditions. In the R & S mixer there is a rotating rotor which provides a strong flow in the axial and radial direction. This rotor guarantees an accurate mix of solid and liquid composition by providing air inlet.
9- Helical Mixer
The helical mixer is a high viscosity mixer used when the turbine and anchor mixer types can not achieve the required fluid movement. The viscosity value is 100,000 and above, the NRe limit is 10.
10- Anchor Type Mixer
The anchor type mixer is used at mid-rate viscosity values to avoid unnecessary cost of the helical mixer. For 2> Re> 10 it makes it possible to add the non-moving areas to the mixture.
