Traditional versus new technology is always a battle across all industries and even in everyday life. However, when it comes to industries and plants in the majority of cases, it comes down to cost-effective, efficiency and durability. Let’s compare tank or dynamic mixers against a static mixer.
A tank or dynamic mixer is a mixer with any moving part, such as an impeller. It is a tank with a center-mounted mixer motor, shaft, and impeller.
Static mixers are usually sections of pipe with a convoluted insert that causes the media to change direction over and over again to achieve mixing. The mixing energy comes from the flow rate through the pipe. A static mixer also eliminated air from getting into the mixer, which can affect bonding in liquids.
When deciding upon which is the better fit for your needs, comparisons need to be made on energy efficiency, maintenance, space and time.
Tank Mixers are large and require a large space and materials to be able to efficiently perform the mixing. This makes the mixing time very long, quite possibly over a period of days.
Static mixers blend the materials as they are extruded, dramatically reducing the mixing time. They also do not require a large space they are part of the piping. They need no extra space to put them into a plant.
Tank mixers run on electricity and require an external power source. When large amounts of materials are mixed, not only does the production time increase, but also the expenses increase because of the high energy costs.
Static mixers have no moving parts, require no electricity, thus not contributing to the growing power consumption. They cut down on energy costs.
Tank mixers are more difficult when it comes to maintaining and cleaning.
Static mixers have the clean in place (CIP) option, making them easy to maintain and clean. As well as with no moving components makes it easier to clean. Because they lack moving parts, there’s very little need for maintenance or replacement parts.
Komax created a Triple Action Static Mixer that includes 3 distinct types of mixing: Two by Two Division, Cross Current Mixing, and Counter-Rotating Vortices & Back-Mixing.
A static mixer is a precision-engineered device that is used for the continuous mixing of materials without moving components. There are so many designs of static mixers and construction materials, they can fulfill so many applications. Which is why many plants are moving away from tank mixers and going with static mixers.
