Heavy Duty Line Vac Solves Alumina Spillage Problem

Spilled alumina material which needs to be vacuumed and returned to the main hopper.

The image above shows spillage of small alumina particles at an aluminum manufacturing plant in South America.  This customer needed a method to vacuum the spilled material and return it to the main hopper.  The ideal solution needed to be compact, simple, and provide repeatable results.  All of these are key aspects of EXAIR Line Vacs, so we began discussing application variables to make a solution recommendation.

Whenever we consider Line Vac applications we always explore the following variables:

  •      Bulk density of the material
  •      Size of the material
  •      Conveyance height
  •      Conveyance distance
  •      Required conveyance rate
  •      Available compressed air supply

The spilled alumina in this application has a bulk density of 1.1 g/cm³ (~68.7 pounds/ft³) which needs to be conveyed to a height of 3.3m (~11ft.).  The conveyance rate is not mandated, but the alumina particles are rather small in diameter and the customer wanted to move as much material as possible in as little time as possible.  Compressed air is readily available at proper pressures and flows, so we were left to determine whether a Line Vac could be a viable solution.  Fortunately we’ve found success in transferring alumina with our Line Vacs in multiple applications before, so we were confident we could find a solution here as well.

The height of this application is 3308mm (~11ft.) – an easy conveyance height for an EXAIR Line Vac.

After exploring the specifics of this application we determined the best solution to be the 2” Heavy Duty Line Vac model 150200.  The 150200 Heavy Duty Line Vac can easily move the alumina to a height of 3.3m at an estimated conveyance rate of 11kg/minute (25 pounds/minute).  There are no moving parts to wear out, which means little to no maintenance and reliable performance each time the Line Vac is used.

Our local distributor assisted with product procurement and in-country technical support.  So even though this customer was in a different continent, we were able to quickly get them the assistance and products they needed to solve their problems.

Custom Products for Custom Applications

Here at EXAIR we pride ourselves on the number of problem solving products we have on the shelf that can ship same day if ordered by 3 PM Eastern Time. But some times a stock product doesn’t quite fit the bill for every application.

Since EXAIR manufactures our products at one location in Cincinnati, Ohio, this gives us the flexibility to do many things like making custom configurations with our Line Vac Systems.  Here is one example of a custom Line Vac and how the customer is using it!

The photo above shows two custom 1″ Aluminum Line Vacs with custom threaded outlets. This customer wanted to use the line vac to remove fumes from a welding application and wanted to attach one of their flame retardant filter bags to the outlet of the Line Vac! These custom threads allowed them to screw the filter bag directly onto the line vac with the added insurance of a threaded connection to prevent sparks from escaping the bag.  

No matter what your application is EXAIR is capable to work with you to create custom solutions for your application. Whether you need a different material, size or dimensions or design, EXAIR is able to meet your requirements. These Line Vacs represent only one of our many product lines that can be custom made to your specifications.

For more information on EXAIR’s Line Vacs or help with customizing any of EXAIR‘s Intelligent Compressed Air® Product lines, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

EXAIR Line Vac Promotion until October 31, 2019

 

LV_hero

EXAIR will be giving away a free 2” Super Air Nozzle with the purchase of any EXAIR Line Vac from September 1st through October 31st, 2019.  This special promotion will apply to all versions of Line Vac orders, whether aluminum, stainless steel, heavy duty, threaded/non-threaded, or 316SS sanitary flanged.  Order within the promotional period and receive the free model 1122, a value of $65.00! The 2″ Flat Super Air Nozzle is more durable than plastic flat nozzles, operates at lower noise levels and produces a powerful blast of compressed air in a laminar sheet.

Lightweight and durable aluminum is the most popular choice, but we make them in stainless steel (Types 303 and 316) for heat and corrosion resistance. For extreme heat, the High Temperature option affords protection to 900F (482C) in either 303SS or 316SS.

Line Vacs provide a fast, easy way to pneumatically transfer dry materials from one location to another.  They eliminate the need to have personnel manually transferring materials via bag, super sac, or bucket-and-ladder setups.  Doing so reduces worker fatigue and allows conveyance to occur simultaneously with other process operations.

The Line Vac conveys scrap trim quickly and easily, and can be sized for most any product.

 

 

 

 

 

 

 

 

 

Depending on application parameters such as bulk density of the material (lbs/ft³ or kg/m³), conveyance height/distance, and required conveyance rate, we can size a Line Vac properly through the support of our Application Engineers who have years of experience working with these products and their implementation into industrial solutions.

We’re here to help you find a pneumatic conveyance solution for your application, and earn a free nozzle in the process.  Contact our Application Engineers for assistance today.

EXAIR’s Super Air Knife Eliminates Problem of Fused Packages

The EXAIR Super Air Knife – high force with precision flow

An Argentine food manufacturer recently reached out to our distributor in Buenos Aires (AYRFUL) to discuss a potential application for EXAIR products.  The need became clear when a packaging line for soon-to-be-frozen food began experiencing problems with excessive water on the surface of the packages.  In this process, the packages are rinsed to remove any unwanted debris, and then sent into a large freezer before distribution to local groceries.

The excessive water on the packages would become ice, which would fuse the packages together when stacked in boxes for transporting to retail centers.  This fusing caused rips in the packaging when they were separated, thereby creating unsellable goods, ultimately leading to returns for this manufacturer.  And, the residual water also increased the total weight of the packed packages, enough to increase the actual weight when bulk packed.  This increase in actual weight led to an increase in freight costs from their courier.  So, this manufacturer needed a way to remove the residual water, reduce defects and returns, and simultaneously lessen the freight cost.

Model 110048 Super Air Knife (inside red box) blowing off residual water after rinsing and before freezing. See note on plumbing below.

The solution they found was a 48” EXAIR Super Air Knife, model 110048, mounted using (2) Universal Air Knife Mounting Kits.  The Super Air Knife in this application provided a precision airflow to blow off the water from the top of the packages, after rinsing and before freezing.  Removing the water at this stage, as shown above, eliminated the problem of fused packages, rejected products, returns, and increased freight.  And, the Super Air Knife was able to do this at a low operating pressure, fed from a single compressed air inlet.

(Note – EXAIR recommends plumbing multiple compressed air inlets for Air Knives longer than 18”.  For this model, 110048, we recommend compressed air be supplied to (3) compressed air inlets.  Plumbing less inlets will reduce the compressed air flow into the knife, which reduces possible operating pressure.  In this case, the lower operating pressure was acceptable, however, we still recommend to plumb (3) compressed air inlets on a 48” Super Air Knife.)

Plumbing specifics aside, this solution still brought tremendous value for the customer.  They were able to solve the root cause of a multi-faceted problem with an engineered solution.  If you have an application in need of an engineered solution, contact an EXAIR Application Engineer.
