When searching the surprisingly vast range of options in industrial mixers, few companies ever find themselves underwhelmed. In fact, quite the opposite is true. With such an expansive variety of models to choose from, selecting the right one for any application can be daunting to say the least. Following are several tips to make these efforts infinitely easier.
Start By Defining Your Needs
There are multiple factors that must be considered whenever attempting to choose a unit for any specific application. Among these are the viscosity of the liquids that you’ll be mixing, the necessary capacity of the container, your requirements for torque and horsepower, the diameter and rotational speed of the propeller, and the nature of the required mixing cycle. You’ll also have to decide which type of power supply will be suitable for your facilities and operations. Once you have a clear understanding of your needs in each of these areas, finding an appropriate model will take far less time.
Determine Your Needs For Capacity
To identify the correct capacity for your mixer, calculate the application volume, the maximum height of the batch, and the diameter and height of the tank. Keep in mind that in many industrial operations, batch sizes may vary from time to time. As such, you should base your calculations on the maximum, known batch quantities in order to identify the most appropriate blending machines for your facilities.
Look For A Mixer That Can Stand Up To The Demands Of The Liquids You’ll Be Using
Liquids are typically classified according to the behaviors that they exhibit, especially when subjected to changes in temperature. For instance, lotions, latex, gels, and paints are categorized as pseudoplastic liquids that will decrease in viscosity when mixed at increasing speeds. Newtonian liquids such as water, mineral oil, and hydrocarbon, however, will maintain the same viscosity at every mixing speed. Dilatant liquids will become thicker and more challenging to mix at increased mixing speeds due to relative increases in temperatures and their viscosity. Slurries, clay, and candy compounds are several examples of dilatant liquids.
Check Horsepower And Torque
In mixing technologies, horsepower and torque go hand in hand. Torque is the rotational force of a motor that’s usually measured in ounces or pounds. Your needs for torque will be determined by the solutions that you’re mixing, and the expected changes in their viscosity. Horsepower determines how efficient a mixer’s motor is in relation to revolutions per minute (RPMS) and torque. It’s important to note that even very minute changes in RPM or the industrial mixer‘s impeller can significantly increase the amount of power that’s needed for effective mixing.
Consider The Conditions Of Your Lab
Laboratory conditions will often determine the best power supply for these units. In certain instance, air-driven models are required due to safety concerns pertaining to the use of electricity within these environments. In facilities in which other electric equipment exists, standard electric mixers will likely suffice.
