Compressed Air Uses In Industry

From pneumatic hand tools like impact wrenches or nail guns to larger scale industrial applications like stamping presses, the use of compressed air can be found in almost any industry. In fact, it is often referred to as a “fourth utility” next to water, gas and electric.

Compressed air is used in virtually every industry!

 

Take for example in construction, workers will use a pneumatic riveter to join steel framing because of the power generated by the tool over an electrically powered device, not to mention it provides for a safer operation by removing an electrical hazard. Many companies use compressed air operated diaphragm pumps or air motor driven pumps to move expensive or viscous liquid from one location to another. These types of pumps are self priming drawing the liquid in and provide positive displacement meaning they fill and empty the liquid chamber with the same amount of liquid through a common inlet and outlet.

Amusement parks have used compressed air in some capacity in the operation of thrill rides like roller coasters or to enhance the effect of certain attractions. Compressed air can be found in hospitals where it is used for specialized breathing treatments or to power surgical instruments in an operating room. Educational facilities use compressed air for laboratory testing. You can even find compressed air in the tires on your car. Basically, when you think about it, compressed air is being used just about anywhere.

Here at EXAIR, we manufacture Intelligent Compressed Air Products to help improve the efficiency in a wide variety of industrial operations. Whether you are looking to coat a surface with an atomized mist of liquid, conserve compressed air use and energy, cool an electrical enclosure, convey parts or dry material from one location to another or clean a conveyor belt or web, chances are we have a product that will fit your specific need.

EXAIR has been providing engineered solutions since 1983.

How Do You Make Cement? Start with Clinkers

Last week I wrote about the use of the Atomizing Nozzles to create a fog for wet room curing of concrete samples poured during road construction.  This week, I had the opportunity to work with another customer about concrete, but this time it was regarding the the manufacturing process.  Invariably, I always learn something new , and for this interaction, it was the term ‘clinkers.’

Concrete is a composite material composed of coarse aggregate bonded together with a fluid cement that hardens over time.  The customer I was working with was a cement manufacturer.  Cement production is basically a 2 step process – 1) clinker is produced from raw materials and 2) cement is produced from cement clinker.

Typical Cement Clinkers

To make the clinker (step one), several powder raw materials are fed into a rotary kiln.  The kiln is heated to very high temperatures, and when the materials are mixed and heated, new compounds are formed and hydraulic hardening occurs resulting in the formation of the clinker.

My customer needed a way to clean off the residual dust left on the transport belts, after the clinkers were transported to storage silos.  Due to the high temperatures in the area, we focused in on the EXAIR Type 303 Stainless Steel model of the Super Air Knife, as it can withstand temperatures up to 800°F.  The customer went with (3) of the Super Air Knife Kits, which include the Shim Set, Auto Drain Filter Separator, and Pressure Regulator w/ Gauge, for easiest installation with maximum functionality.

The Super Air Knife is a tried and true product for cleaning, drying, cooling and general blowoff for conveyors.  And with widths up to 108″ available, any size conveyor can be handled.

To make cement (step two), the clinker is ground into fine powder with other ingredients including gypsum (calcium sulphates) and possibly additional cementitious (such as blastfurnace slag, coal fly ash, natural pozzolanas, etc.) or inert materials (limestone). It is then stored or packaged and ready to be made into concrete.

To discuss your application and how an EXAIR Super Air Knife can benefit your process, feel free to contact EXAIR and myself or one of our other Application Engineers can help you determine the best solution.

Super Air Knife Used in Mining Application

If you were to look at a graphical representation of the exports from some countries (such as Chile), copper, copper alloys, and other metals would dominate over 50% of the graph.  In order to get all of those metals exported out of the country, they first have to be mined and, in many cases, separated from other, undesirable items, such as rocks or dust.  And, in order to separate the materials, many end users place the products on a conveyor and blow off what isn’t wanted.

We receive calls and emails at EXAIR regularly for these types of applications.  Recently, I received one such email about an application in need of dust and dirt removal from a conveyor during a mining operation.  The conveyor belt had become overrun with dirt and debris that couldn’t be removed by conventional means.  So, the end user sought an alternative, and permanent solution.

It was at this point that the Super Air Knife was considered, and after measuring the width of the conveyor we realized a stock model 110018 would work well.  Following installation of the Super Air Knife, the dust and dirt was removed to within an acceptable level, and the end user sent me the pics below.
