A Perfect Product for Material Conveying
When it comes to bulk material handling, an air-tight seal is critical for success. US Tubing offers a clamp together connection that is fast to assemble and easy to modify without sacrificing the secure seal needed for transporting material. Be it grain, coffee beans, or non-food particulate, US Tubing has you covered.
A Few Words About Pneumatic Conveying
A properly designed air flow system to transport bulk material from one point to another is often the most practical and economical means. Materials may be conveyed with a blower system either by the direct method, where material passes directly through the blower, or by the indirect method, where the blower furnishes the flow of air for conveying but the material does not pass through the blower.
Most pneumatic collection and conveying systems incorporate some type of hood or inlet device to properly pick up the material to be conveyed. Some state or local codes dictate the design criteria. In all cases the hood design should minimize turbulence, offer the lowest possible entrance losses and mechanically prevent the entrance from choking off and stopping the air flow. If the material enters the pressure side of the system, an air lock or similar device should be installed to prevent a blow back.
Since the purpose of any pneumatic conveying system is to move material suspended by air, the ratio of material to air (by weight) is very important. A conservative design approach is to keep the ratio of material-to-air below a 1:2 proportion. For example, if it is required to convey 1800 Lbs/Hr of sawdust through a 6” diameter duct, 800 cfm of air flow at 4073 FPM velocity would be required.
The pipe, or ducting used to convey the material should provide a complete seal from ambient air. US Tubing offers the necessary seal in conjunction with an easy-to-use clamping connection system. Flange and gasket connections can be used for larger (>18”) diameter pipe.
The material for the ducting system can be carbon steel, galvanized metal, non-ferrous metal, stainless steel or painted/coated metal. Your application specifications will best dictate the material needed. Most options are available in US Tubing’s clamp-connect and flange connect systems.
Pneumatic conveying systems do have their limitations, such as material size and temperature. However, they still provide many benefits. In addition to being very economical, they are also useful in controlling or minimizing product loss, improving dust control, reclaiming product and thus improving overall plant conditions.
