Internal Mix Atomizing Spray Nozzle Used In Feed Additive Process

Last week I took a call from an agricultural customer looking to replace the spray nozzle used in their feed additive process. The soy oil/beeswax solution they are applying to the feed, is slightly viscous (close to 100 cP) which seems to be clogging the tight clearances inside the current nozzle, resulting in varying flow rates and an erratic spray pattern. They had tried to contact the current manufacturer several times for a solution but were unhappy with the lack of assistance they were receiving, not to mention the long lead times of 6-8 weeks for a replacement.

After further discussion, they confirmed they weren’t as concerned with the flow rate or spray pattern, as they were with the nozzle potentially getting clogged.  They were able to obtain some internal dimensions of the existing nozzle and after further review, I recommended they use our Model # AF1030SS Internal Mix Flat Pattern Atomizing Nozzle as a replacement. This nozzle has larger inside diameters which would reduce the potential for clogging. Our Internal Mix Atomizing Nozzles mix the liquid and air inside the air cap and produce the finest atomization. The flow rate can be changed by adjusting the control valve on the nozzle and/or by adjusting the liquid pressure. Internal Mix nozzles are capable of handling fluids up to 300 Centipoise. All of our Atomizing Nozzles are In STOCK, so delivery is never an issue.

When considering an Atomizing Nozzle for an application, there are some general parameters that can be helpful in making the best selection.

  1. Do you have a pressurized liquid source?
  2. What is the fluid viscosity?
  3. What spray pattern best fits the process?
  4. How much flow (GPH/LPH) do I need?

If you have an application requiring a fine mist of atomized liquid spray, please contact an application engineer for assistance.

Engineering Makes The Difference In Spraying Application

The Paint Line Engineering Manager for a major agricultural & industrial equipment manufacturer wanted to improve the efficiency of their paint lines. They had “halo” systems through which large parts passed for primer & paint coatings, which were equipped with inexpensive liquid-only spray nozzles:

Liquid-only spray nozzles lack the control and efficiency of engineered solutions like EXAIR's Atomizing Spray Nozzles
Liquid-only nozzles lack the control and efficiency of engineered solutions like EXAIR’s Atomizing Spray Nozzles

You can get a whole handful of these and it’ll still cost you less than one of our Atomizing Spray Nozzles will.  If you don’t have any particular concerns about efficiency, spray pattern adjustment, droplet size or flow control (and a lot of applications don’t require this, and that’s fine,) then these will work GREAT for you.  And again, they’re abundant and cheap.

That wasn’t the case here – turns out, good quality paint is expensive, and every drop wasted adds up.  Getting a fine, even coating on parts of different sizes & shapes, every time, requires precision control of the flow pattern.  And design of an automated system benefits from a wide selection of options to choose from.

Enter the EXAIR line of Atomizing Spray Nozzles.  With (90) models to choose from, we can cover (literally) darn near any spraying application you can come up with.  If you know what flow rate and/or spray pattern you’re looking for (like a Paint Line Engineering Manager would,) then selection is quick & easy.  Paint consumption is down, quality is up…and the reliability of the new system means they’re spending less time and resources on cleaning & maintenance. For the record, the halo system ended up looking like this:

EXAIR Atomizing Spray Nozzles provide efficient, reliable coating.

If you’d like to find out more about how engineered products, like EXAIR’s Atomizing Spray Nozzles, can make a difference to your operations…and your bottom line…give me a call.
