Some Less-Known Facts About Liquid Mixing

Many industrial facilities need reliable and powerful mixers to mix liquids in the most efficient manner. The mixing agitator is very efficient machine for mixing liquids, and is also capable to increase the heat transfer, promote reactions of the chemical substances and keep the liquid homogeneous during storage. Agitators and mixers can be found in almost any industry, but most commonly in food factories, cosmetic industries, chemical labs and in manufacturing facilities. But in order to keep the agitators and mixers working properly, you need to have at least basic understanding about how these machines work, and to know some general facts about the process of mixing liquids. Here are some less-known facts about the liquid mixing process.

Different Types Of Mixers: There are many types of agitators and mixers available on the market. Some are designed for one specific application, while others are more versatile and suitable for almost any liquid mixing application.

Horsepower: The performance of the mixer is usually measured by the amount of horsepower. Different models of agitators and mixers come with different horsepower range, and the one you are planning to use should be powerful enough in order to complete the job in the most efficient way.


Flow: The flow is a measure for the fluid that is being discharged by the impeller. This flow is known as primary flow, while the one that is pushed is called induced flow and together with the primary flow they create the total flow. The total flow of any mixing agitator is very difficult to calculate, and can be measured in a laboratory only. However, it is very important measure that you need to consider when comparing the efficiency of different mixers.

Torque: The turning force that produces rotation on the mixer shaft is called torque, and is one of the most important factors that needs to be considered. The price of the mixing agitator depends on the torque. In other words, higher torque means higher price. Also, the torque affects the size and the type of mixer drive and directly impacts the shaft design of the mixing agitator.

Critical Speed: The last consideration is the critical speed. It is called critical because it is a speed at which the two frequencies reinforce one on another, and potentially has a destructive force. There are mixing agitator types that are able to operate above the critical speed, but you need to pay attention when using such mixers.
