Counter Rotating Mixing Element
Jongia Counter Rotating Mixer type CRM Technical Description
Jongia’s counter-rotating agitator type CRM is a type of mixing device used in various applications.
The function of this type of mixer is to blend, homogenize, or emulsify liquids or powders.
The unique and most important aspect of a counter-rotating agitator is that it consists of two or more stirring elements that rotate in opposite directions. It’s essentially two agitators in one device.
Key features and benefits of a Counter Rotating Mixer:
Counter-rotating agitators provide intensive and efficient mixing by rotating the stirring elements in opposite directions. This reduces dead zones, improves blending, and supports homogenization of materials with different viscosities or densities, such as creams, emulsions, binders, and paints.
They can also be used for dispersion, helping break down agglomerates or separate particles in liquids. In specific applications, they assist with foam control, temperature consistency, and moving material from the vessel bottom to the surface to prevent settling or support discharge.
Overall, counter-rotating agitators are a versatile solution for advanced mixing and processing in industries such as chemicals, pharmaceuticals, food production, and more.
Jongia Counter Rotating Mixer type CRM Technical Description
The two stirring elements are arranged in a stacked configuration. This means that the upper stirring shaft is guided through the hollow drive shaft of the lower drive unit. Both shafts have their own drives and are stacked on top of each other. Depending on the application, such as whether it involves a pressure-holding tank or pressure vessel, the shaft seal will also play a crucial role in the application as well as in the construction.
A counter-rotating mixer is primarily used when this configuration offers advantages that two separate mixers in one tank cannot achieve.
Dual Mixing System
To create a lump-free, homogeneous and stable product in the premix phase JONGIA offers its dual mixing system consisting of an anchor type mixer combined with a fast running dissolver for mixing in additives. The anchor mixer keeps the mixture homogeneous and is fed by the fast running mixer. JONGIA’s anchor mixer can be fitted with wall-contoured scrapers to ensure the best possible axial pumping action for products with a high solids content such as mural paints. When a more gentle product treatment is required, we recommend a parabolic anchor. A single or double 4-bladed axial- flow/multi counter-flow element of our own special design creates the necessary shear forces to mix liquids with low viscosities into high-viscosity products of up to 20.000 cP. The combi-system ensures perfect homogeneity.
Frequently Asked Questions
What is a counter-rotating mixer?
A counter-rotating mixer, like Jongia’s CRM, is a mixing device equipped with two or more stirring elements that rotate in opposite directions. This design allows for efficient blending, emulsifying, and homogenizing of liquids or powders in various applications across different industries.
What are the advantages of using a counter-rotating mixer?
The main advantages include efficient mixing with reduced dead zones, better homogenization of materials with varying viscosities, effective dispersion of particles, foam control, and consistent temperature maintenance, making it ideal for applications in the food, pharmaceutical, and chemical industries.
How do the stirring elements work in a counter-rotating mixer?
The stirring elements are arranged in a stacked configuration, allowing the upper shaft to drive through the hollow lower shaft. Each stirring element operates independently, enhancing the mixing action and enabling customized adjustments based on specific application needs.
What type of products can be processed using a counter-rotating mixer?
Counter-rotating mixers are suitable for producing a wide range of products, including creams, emulsions, paints, and adhesives. They effectively blend materials with different viscosities, ensuring a consistent and homogeneous final product without lumps.
Can maintenance be performed independently on each stirring system?
Yes, both stirring drive systems operate independently in a counter-rotating mixer, allowing for independent maintenance and repair. This feature ensures that the mixer can continue operating efficiently while one system is serviced without downtime.
