As an operator in today’s industrial plants, you are called to be a true jack-of-all-trades.

The effective operator must have multiple skills, advanced knowledge of equipment, an understanding of several mechanical principles, and a bit of chemistry thrown in for good measure. It’s no wonder that a experienced operator in today’s plant is one of the most important people in the company.

Let’s look at a common application…Mixing… From your point of view.

It is common to have batch mixing operations in which dry solids are added to a tank containing liquids to produce a homogenous blend or slurry to be used in a process.

An example of this would be adding sacks of dry polymer to a tank of water.

Unlike some materials that quickly go into suspension, some polymers must be agitated in order to sufficiently “wet out” the powder into a soluble solution. From an operator’s vantage point, this usually means that he or she is looking down at the top of the tanks liquid surface. Since most slurries are not clear, the surface of the liquid is all that the operator can see.

It is a common misconception that an actively rolling surface = a well mixed tank.

On the contrary, the presence of excessive surface action is an indication that the mixer is in the wrong position for effective mixing. Also the presence of a vortex or tornado like activity on the surface of the tank means that air is being sucked into the impeller and is effectively keeping the liquid and solid from being effectively mixed. We have a set of 3 unique videos available in which the operators can learn the correct positioning of a mixer in a tank in order to make their job much easier.

Here are the links to the instructional videos:

Mixing is much more than placing a mixer in a tank and turning it on. Let us show you the difference in a quick and easy transfer of information. You are the heart of the process. We can help you do a more effective job or improve an existing process. We look forward to hearing from you…
