Types of Mixers Used in Industry

Different goods require various mixing methods, and many different kinds of industrial blenders and mixers exist. Industrial mixing can be done at various processing temperatures and operating pressures, depending on the bulk ingredients to be combined. Usually, motors and blades on mixing equipment are constructed to perform specialized handling operations. Blending dry powders, combining highly viscous pastes, homogenizing, emulsifying, agglomerating, or lowering particle size are a few common processing techniques.

Listed below are the types of industrial mixing machines for processing powders:

• Vacuum mixer – Industrial vacuum drying operations can be carried out using heated industrial vacuum mixing equipment that provides a sealed vacuum to blend the ingredients under various pressure conditions.
• Twin shaft mixer – Twin shaft mixer is a homogenizing mixer with mixing arms and two cylindrical mixing chambers.
• Ribbon mixer – A homogenizing mixer that has cutting-edge, helical mixing blades along the shaft and a conical or cylindrical chamber.
• Pin mixer – A tumble-growth agglomerator that produces granules by rolling materials around the edge of a horizontal chamber.
• Mixing reactor– chemically reactive components are added to an industrial mixer with a pressurized chamber for mixing, reacting, and coating.
• Rotor stator mixer– a homogenizing mixer having long, revolving vertical mixing blades that lower from the top; also known as a high-shear mixer.
• Drum blender – A drum blender is a compact industrial blender with a revolving mixing chamber and a helical mixing blade.
• Rotor stator mixer – This homogenizing mixer has long, revolving vertical mixing blades that lower from the top; it’s also known as a high-shear mixer.

Types of Industrial Mixing Technologies

Ribbon Mixing: The shaft of this mixing technology is attached to ribbons. The ribbons, which rotate to break up the contents of a mixing bowl, are often made of thin, sharp, corkscrew-shaped blades. The inner ribbon blades revolve opposite the outer ribbon blades, which causes material movement inside the mixer. Ribbon speeds are changed to get the desired blend. This technique works well with dry, freely moving substances like powders and liquid-solid mixtures. A food blender is a typical example of this type of mixer.

Attrition and homogeneity are two of the biggest problems faced by ribbon mixers. Particularly when working at higher speeds that produce strong shear forces inside the mixer, the ribbon blades frequently cause damage to the particles—the degree of mixing changes within a container as well. A given mix is not consistent or homogeneous throughout the vessel since it is greater closest to the blades. Due to this, ribbon mixers may require an extended operation to attain the requisite mixing uniformity and consistency. Cycle times and operating expenses consequently go up as a result.

Tumble Mixing: Tumbling mixers use diffusion to accomplish the necessary mixing. These mixers consist of a vessel or sealed mixing drum that rotates at a set speed during blending, using gravity to help with material movement inside the vessel. The lack of an agitators in tumblers makes them stand out from other mixing techniques and makes tumblers less susceptible to particle damage and particle size reduction.

However, segregation following mixing, or "overmixing," is a problem for this method. Tumble mixers are, therefore, best suited for liquids and solids where segregation is difficult (namely, materials that do not have large differences in particle size and density).

Planetary Mixing: Planetary mixers use a mixing drum with an impeller or agitator as an attachment. To stir the components in the vessel, the agitator rotates in a circular motion. This motion resembles how planets rotate around the sun, therefore the name "planetary." In many planetary mixers, the mixing vessel is stationary. Still, for applications that call for greater mixing, the bowl can rotate in the opposite direction of the agitator to stir the contents around more. Agitator devices like paddles, whisks, or beaters can be attached to get the ideal mixing results. A stand-up kitchen mixer is an illustration of this type of mixing equipment.

Centrifugal Mixing: This technique, known as planetary centrifugal mixing, blends materials without using an agitator by simultaneously rotating and revolutionizing. The material travels to the outside of the vessel due to centrifugal forces produced by revolution; rotation and tilting of the vessel change the flow's direction and produce shearing forces, which can fast produce much heat.

Due to the interaction of these pressures, a range of ingredients, even those with various densities, can be mixed quickly and uniformly. This kind of mixing also can de-aerate a combination as it is being mixed, which cuts down on or eliminates the time needed to de-aerate after the mixing process.
