Multi Shaft Mixer

So you just found out that the goop that you are mixing is 100,000 centipoise. In other words it’s about as liquid as peanut butter. A normal, one shaft mixer is not going to do what you need it to do. In fact, putting your mixture in a one-shaft mixer could make it come out worse than how it started. What you need is a multi shaft mixer.

 

Dual-Shaft Mixers

When we start talking about multi shaft mixers, we’re talking custom jobs. You can't usually get these at Walmart. They need to be tailored specifically to your needs. Sometimes, you only need a two-shafted mixer. Sometimes you need three shafts. And still sometimes you need four shafts (a Challenger's engine because mixing with four impellers means you have some thick stuff).

The purpose of having two shafts is to push the thick mixture throughout the container in order to make sure you get a good flow. Think about it. If you were mixing peanut butter, it would not flow around the container easily. In fact you’d probably just spin the impeller of the mixer and only mix the area immediately around the impeller because the impeller does not have enough power to push all the peanut butter around the tank. So, you get another shaft and impeller.

 

A single shaft mixer in a thick mixture wouldn't get a whole lot of flow. A single shaft mixer in a thick mixture wouldn't get a whole lot of flow.

The way you set up the dial shaft mixer varies on your application. If you are mixing in wide container, you might want you two shafts to be the same length so that you can put radial flow impellers on the shaft in order ensure horizontal mixing.

The more likely scenario is that you’ll have different length shafts with axial flow impellers on them to ensure vertical mixing. The top axial flow impeller will push the mixture at the top of the tank towards the lower impeller which will in turn push the mixture towards the bottom of the tank. The continued pressure from both impellers will force the mixture from the bottom of the tank, up the sidewalls, back to the top impeller.

Now, if you’re getting into something really complicated, you might be thinking about putting a dispersion blade on one of the shafts and an axial flow impeller on the other. You’d do this if you want to break up the material that you’re putting into you tank before it gets down to the second impeller. Then again none of these configurations might work for you specific application and you might need to go on to a three-shaft impeller.

 

Triple-Shaft Mixers

A three-shaft mixer usually has two impellers and an anchor. The anchor is a type of impeller that has long arms and spins around the sides of the tank. We recommend Teflon coated anchors since they scrape against the side of the wall. Just like you’d want to protect your cookware from scratches with Teflon, you want to do the same with your anchors. As the impeller scrapes the edges of the tanks the mixture on the walls of the container gets pushed back into mixing impellers. Again, depending on your application, you’ll have a combination of axial flow impellers, radial flow impellers, and dispersion blades.

What Makes Ours Different?

Three words: We customize it.

We customize every order. We don’t do the whole song and dance where you call in, we tell you what you need the most expensive thing we make, and you order it. You call in and we customize your mixer for your specific application. We don’t have a “one size fits all” approach. We have a “your size fits you” approach, so we tailor all of our mixers to your specific needs.

What are some of those specific options? Well, we can make these mixers explosion proof. We can customize the motor horsepower for each individual shaft. We can make a mixer and tank combo where the tank is removable. We can also make the tank vacuum sealed. We can even paint them to look like Disney characters (if you are Disney or own the copyright to the characters).

If you have another custom need, call us up (or if you’re feeling froggy you can tweet us @mixerdirectinc). You can literally reach the guys who design the mixers and talk to them about it without having to go through 47 salesmen, 10 accountants, and the janitor. Call 812-202-4047, press one, and you’re talking to a live human being who can tell you what you should be looking for. Or you could just send an email to us.

It’s simple really. We want to give you the expertise that you want in order to make sure that you are getting the tank that you need at a satisfying price.

That’s what makes our tanks different.

It also doesn’t hurt that we’re pretty darn good at what we do, too.
