Fine powders often need air injection to increase flow rates to an acceptable level. With entrained or injected air, powders flow like water, but when deaerated, the extremely low flow rate may be confused with a hang-up or arching condition.
Buildup is a potential danger in horizontal pneumatic conveying systems, particularly when velocity is reduced. This exclusive contribution from the Particulate Solids Research Institute addresses this issue.
Plant engineers who find it is difficult to get good level measurements have plenty of company. A recent poll shows that it is considered to be one of the two most vexing problems by process automation professionals.
Pneumatic conveying has long been a popular choice for moving bulk materials. However, the technology hasn't been standing still, and this can influence the choice between several types of pneumatic systems.
There are numerous industries that depend on size reduction to improve performance or to meet specifications. This article details size-reduction techniques and equipment that may assist you when handling these materials.
The HART Communication Foundation is an exclusive contributor to ChemicalProcessing.com. The Foundation is an independent, non-profit organization that provides worldwide support for application of the HART Protocol.
Particulate solids are often required to be introduced into a flowing gas stream. If not done correctly, introduction of solids into the gas stream can lead to impingement of solids on the pipe, resulting in erosion of the pipe in the area of the solids introduction.
