A Primer on Dense Phase Pneumatic Conveying Systems

Dynamic Air Inc., a major leader in the dense phase pneumatic conveying industry, is a specialist in the pneumatic conveying of dry, bulk solids. Applications range from food to poison, from light fumed silica to heavy powdered metals. However, all of these applications have one thing in common, the necessity to control the conveying velocity in order to control particle degradation, conveying pipe wear, minimize air consumption, or eliminate pipe line plugging. What is Pneumatic Conveying? Pneumatic conveying is nothing more than creating a pressure differential along a pipeline and moving a bulk material along with the air as the air moves towards the area of lower pressure. This can be done with a vacuum inducer, or with compressed air being injected into one end of or along the pipeline. Dilute Phase vs. Dense Phase Pneumatic Conveying The two most distinct categories of pneumatic conveying can be described as either low pressure (dilute phase) or high pressure (dense phase) systems.

Vibratory Finishing: Versatile, Effective, and Reliable

As industrial manufacturing standards evolve, tried-and-true mass finishing processes must keep in lockstep with end-user demands. Mass media finishing processes have gained widespread acceptance in many industries, primarily as a technology for reducing the costs of producing edge and surface finishes. This is particularly true when manual deburring and finishing procedures can be minimized or eliminated. There are a number of different mass finishing processes in common use throughout industry. Among these are barrel, centrifugal, vibratory, and spindle finishing. Vibratory systems have become the predominant method due to advantages inherent to the method in terms of ease of use, automation, and material handling. When first developed in the 1950s, these systems were typically modest in size, and were used for deburring and finish processing of smaller components. Being able to process larger batch lots of modestly sized parts was important to competitiveness.

Vibratory Feeders Act as the ‘Hands’ for Many Manufacturing Processes

Vibratory bowl feeders are considered the oldest yet still most used automated industrial parts feeding solution. The basic design of the machine is a feeder bowl configured with a spiral track and equipped with a vibrating drive unit. As parts are fed into the bowl, the vibrating motion facilitates the sorting. Parts are vibrated onto the track and only correctly oriented ones leave the bowl. The track is designed to ensure consistent, repeatable positions, according to specified requirements. Incorrectly positioned parts are pushed back into the bowl to be redistributed. Vibratory bowls are great solutions for small parts handling. For example, washers, being small in diameter and quite thin, could have a tendency to overlap on top of each other. Not with the right vibratory feeder! The specially configured track will feed in a single row every time. There is no double-feeding because the parts that try to override others are pushed back into the bowl.

The Role of Sanitary Stainless Steel Tanks in Beer Brewing

Also used in dairy processing tanks, sanitary grade stainless steel tanks have a very specific type of finish. A sanitary finish, which is typically matte, is applied through electropolishing, as opposed to more typical mechanical and brushed finishes. The electropolishing process consists of a temperature-controlled bath in an electrically conductive solvent and a direct electrical current which is introduced to the bath. The result is that the outer surface of metal is completely removed with the kind of precision that can only be achieved through electrolytic processes. Sub-microscopic peaks and valleys on the surface of the stainless steel are removed, and the stainless steel regenerates a surface layer of passivised chromium oxide to protect it against rust and corrosion.

7 Common Types of Industrial Mixers

In the process manufacturing community, the mixing experts are the mixing equipment manufacturers, and they understand how different blades, speeds, mixer configurations and bowl shapes interact with different types of substances during the mixing process. There are nearly as many different types of mixing as there are products to be mixed – from industrial slurry adhesives to milk homogenization to bologna meat mixing, industrial mixers work differently to achieve smooth blending…

Blast off that Dirt, Paint, Rust and Debris

From small parts to ships, cars and buildings, sandblasting is a way to clean off unwanted paint, dirt, rust and debris; prepare surfaces for painting, plating and coating; and create texturing, roughening, etching and detailing. Sandblasting is an industrial-strength cleaning method great for eliminating all the caked-on gunk and grime that inevitably builds up on surfaces over years and years. Sandblast cabinets can in minutes get a filthy part down to shiny metal, but they can also perform more delicate procedures as well. Depending on the amount of pressure and type of media used, sandblasters can completely strip parts or just polish and decorate them…

Modern Man’s Fire: Industrial Ovens and Their Many Applications

Our knowledge of curing, tempering and baking has given rise to tools, cars, skyscrapers, utensils, polymer-painted furniture and all manner of processed foods. Food production and metallurgy, two of civilization’s most essential processes, are dependent on heat energy, and today we are more dependent on food processing and metallurgy than any of our ancestors. Ovens are key to these processes, being essential in nearly every type of food processing, metal heat treating and polymer binding. In manufacturing, industrial ovens catalyze the curing, tempering and sintering which cause metal parts and polymers to become solid, strong and resilient. Since industrial ovens have such an extensive range of applications, we’ll review their main types and applications with a list…
