Jan 05, 2015· My article "Theory and Design of Dilute Phase Pneumatic Conveying Systems" was published this month in Powder Handling and Processing magazine. This article gives an easy to use Excelbased calculation method for designing new dilute phase pneumatic conveying systems or for improving the performance of existing conveying systems.
These constitute the most widely used of pneumatic conveying systems. DensePhase. There is no universally agreedupon demarcation of when a dilutephase (materialintoairtostream) system becomes a semidense phase or densephase plugflow system. For US Systems, a densephase system is a system that requires a rated pressurevessel.
For dilutephase conveying, values are typically up to about 15, although they can be higher if the pressure gradient is high, as with a short pipeline or a high pressure drop. For the densephase flow of materials, such as fine fly ash and cement, values can be in excess of 100,
The key difference between pneumatic and hydraulic/slurry conveying of solids is that the carrier gas will expand continuously as it goes along the pipe. The flow regime in the pipe (dense or dilute phase) will depend on the ratio of gas to solids and the characteristics of the particles. This workbook contains 2 sheets: Dilute Phase Properties
With its low profile, it is able to squeeze in tight spots where dilute phase systems can not go. This model can handle the rigors of transporting ash with temperatures as high as 350°C. A variety of ashes ranging from the light biomass ash to the gritty waste fuels ash are easily handled and transferred using a single pipeline from multiple ...
Pneumatic Conveying typically refers to the movement of dry powders or pellets from point A to point B in a pipe or tube by means of a difference in pressure. The method has been practiced by industrial manufacturing and utilities for many decades.
Mar 29, 2017· Densephase vacuum has a limitation on conveying distance — 60 to 90 meters (200 to 300 feet) — based on the energy that can be produced by a vacuum blower or pump. This method is also very well suited to fragile and/or sticky materials because the material is pulled through the convey line rather than pushed, as in a pressure system.
Apr 11, 2016· design example – dilute phase pneumatic conveying A plastics production plant wants to increase the capacity through an existing conveying system. The existing system has 6 inch ID pipes and is configured as shown in the diagram below.

The following diagram depicts the different phases of pneumatic conveying and the pressure/velocity associated with each type of flow: 4. How do I select a pneumatic conveying system for my application? There is no clear answer as to which classification, dilute phase or dense phase, is better.
Reducing your densephase pneumatic conveying system's demand on plant compressed air Determining which system and components will best meet your needs IV Engineering study: Solving a plugging problem in pneumatic conveying lines
SPP Series Dense Phase Conveyor. The SPP Series Dense Phase Conveyor is a lowvelocity, pneumatic conveying system designed to move a wide variety of difficult powdered materials cleanly and efficiently, with minimal degradation and separation. They can convey up to 200 equivalent feet.
Mar 26, 2015· Densephase pneumatic conveying is also best described with an analogy: It's similar to what happens in making sausage, when you use high pressure to force ground meat into a casing. An ideal densephase conveying system would extrude material with enough pressure to transfer it in one long, continuous piece through the pipeline's entire ...
