Industrial Mixer

When manufacturers need to break down materials, they use industrial mixers. These equipment are also used for blending, emulsifying, and homogenizing different materials into a single product. Consequently, entrepreneurs need to understand the different types available and their specifications before investing on an industrial mixer. This guide provides important factors to consider when shopping for a mixer for the different applications.

Mixer Types


Planetary mixers have an individual shaft with two rotating blades around it. These are most effective for stirring, shear, and intermixing since the blades rotate around a center of axis.

Paddle mixers feature fixed arms and a horizontal rotating shaft with paddle-shaped feet attached to it. Paddle mixers achieve the mixing objective by pushing materials from one shaft to the other.


Conical screw mixers feature a conical hopper within which a screw rotates. The screw is designed to push force materials upwards, which fall back again by gravity to achieve mixing. The solids being mixed exit the structure at different levels and replaced by other materials at that level. The end result is an even, homogeneous mixture of the desired quality.


Rotor-Stator Mixer draws its name from industrial motor configurations that have static and rotating parts fixed together. In rotor stator mixers, an impeller rotates within close proximity of stator housing. The rotor is responsible for crushing while the stator confines the particles and directs their flow. This configuration is best suited for breaking down solids and emulsifying applications.


Factors to Consider When Selecting a Mixer

Material Type


Different materials require different mixer specifications. For instance, mixing adhesives and sealants requires powerful mixers to move around the high viscosity ingredients. Entrepreneurs can choose between top entry and side entry options. On the other hand, design for chemical industrial mixers requires use of materials that cannot be corroded by the ingredients in use.


For oil and gas applications, industrial mixers used must adhere to the safety requirements in the sector. In cosmetics, the first priority in agitator design is to prevent the possibility of cross contamination. On the other hand, material selection is crucial to meet the sanitary specifications for pharmaceutical process mixers.


Before making your investment, consider the concentrations required for your ingredients and their solubility. As for viscosities, the initial and end products may require different mixers. Also note the specific gravity of the ingredients.


Material state

Liquids and solids require different mixing approaches. For instance, some applications require grounding solids then adding a liquid gradually. Proper mixing must be acquired since the product can easily agglomerate if the wrong mixer is used. Mixing clay particles in preparation for molding is a good example for this application. A mixer used to process powder or granules is structurally different from the one that handles slurry.


Additional Mixer Features to Consider


Although material type is the mostly used specification for an industrial mixer, investors need to consider additional features. Some applications may incorporate heating or cooling, while others need timing. Once the investor identifies the targeted process, modifications can be made to accommodate process control devices such as sensors.


Modern Technology in Industrial Mixer Designs


The advancement of technology has made it possible to come up with industrial mixer designs that were impossible in the past. Apart from satisfying process specifications, aim at improved attachments such as agitators. Other attachments that have witnessed fast technological advancements include heat flow and transfer efficiency, control of shear, powder induction, homogenization, and emulsification.
