EFFECTIVE TANK MIXING FROM AN OPERATORS POINT OF VIEW

Jan 21, 2014   //   by David S. Pratt   //   Uncategorized  //  No Comments

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…

Hunter Equipment Company’s role in our customers/manufacturers eyes:

Apr 5, 2013   //   by David S. Pratt   //   Uncategorized  //  No Comments

The role of distributors and/or manufacturers representatives in the procurement process is often misunderstood. Some customers wonder if it would be easier and less expensive to bypass this step and deal directly with the manufacturer in an effort to “cut out the middle man” and save money as a result.

Some manufacturers have made the switch in both directions, changing from direct factory sales to a distributor/rep or gone from distribution back to direct sales. Naturally their intent is to capture more market share and profits from their operations.

Therein lies the question…What benefits do I receive when dealing with Hunter Equipment Company?

With 30 years experience in this industry and having celebrated the 19 year anniversary of starting my company on April 1, 1994, I feel that I have a firm vision of what we bring to the table. I see HEC as a liason between our customers and the manufacturers that we serve. Dealing with highly technical, specialized industrial equipment designed to handle the worst abrasive, corrosive, and dangerous slurry applications—we provide experience, expertise, and consistent performance in the process of supplying the right product at a fair price. Continuous follow up as the process progresses from RFQ to Order to Delivery and Startup and onsite support gives our customers the information they need before during and after the products are onsite and integrated into their process.

Sometimes, our role is to find a better solution to an existing maintenance or operational problem. We join the technical decision makers of the customer with the technical experts of the manufacturers we represent, providing the necessary technical data and field observations to assist in improving the efficiency and reliability of the process. Once the order is placed, HEC is responsible for insuring that the logistics are in place and the customer is informed of the progress of the equipment as it goes through the manufacturing, shipping, and delivery process.

We follow our products until installation and assist the plant in start up and performance evaluation. We are there every step of the way adding our knowledge and experience to the process.

Most important to the customer:  The use of distributors adds nothing to the final cost to the end user.

Most important to the manufacturer:  Distributors are not paid employees and earn their living supplying quality goods and services to the satisfaction of their customers…or they simply go out of business…
