Understanding dense-phase conveying I n the world of pneumatic con-veying, there are two system types: dilute- and dense-phase conveying. Dilute-phase conveying is the most common of these two systems, due in part to its relatively straightforward design. If designed correctly, a dilute-phase conveying system can provide reliable and flex-

Apr 11, 2016· 29 Top Ten Tips for Dense Phase Pneumatic Conveying 1. The term "dense phase" is often misused in practice. For example, many so-called "dense-phase" systems are found to be operating in dilute- phase (or suspension flow).Also, many researchers and designers define "dense-phase" as a flow mode with solidsloading greater than 10 or 15.

Dense Phase Pneumatic Conveying is a method for moving difficult, abrasive or friable materials, at slow speed. It pushes material along an enclosed pipe, in a plug form, using small amounts of gas, at a low velocity but high pressure. The low velocity of dense phase conveying allows for less wear and tear on both the system and the materials ...

dense phase, as illustrated in Chapter 8, low pressure conveying is generally lim-ited to dilute phase conveying, unless the conveying distance is very short, as will be seen from Figures 11.1 to 11.4. In dilute phase, however, almost any material can be pneumatically conveyed, regardless of the size, shape and density of the particles.
Dense phase Excel calculation tool (scale up) You can access the calculation Excel sheet here As mentionned above, dense phase conveying is always a delicate conveying process and a design should always be done with a recognized company, the procedure above being only for awareness, to have a rough idea of the scale up, and not detail design.

This article gives an easy to use Excel-based calculation method for designing new dilute phase pneumatic conveying systems or for improving the performance of existing conveying systems. Regards, Amrit T. Agarwal Consulting Engineer Pneumatic ...
Pneumatic conveying is a common method for the transporting granular media, where grains are driven through pipes by air ﬂow. It is used in the food industry and in civil and chemi-cal engineering. There are two modes of pneu-matic conveying: dilute and dense phase con-veying. Dilute phase conveying …

Jul 26, 2007· Does anyone have a copy of the excel based spreadsheet for the example calculation in Armit's"Theory and design of dilute phase pneumatic conveying systems" article. I am trying to copy the example to match the article results and I can not get the same numbers.
solids loading ratio of 10, for example, it could be conveyed in dilute phase or dense phase. It would only be with the value of the conveying line inlet air velocity that the mode of flow could be determined. But in the case of dilute phase conveying the preferred ratio of solid to air is 2:1. Conveying capacity
1. Basis for the Calculation Method The calculations for the design of a dilute phase conveying sys-tem are based on determining the pressure drop that is gener-ated in the system due to the flow of gas and solids. ZENZ and OTHMER state that this pressure drop, for both dilute and dense phase conveying, is composed of six effective forces:
Dense phase pneumatic conveying is less common than comparable dilute phase because of the greater capital investment involved, if there is no need to be concerned about breakage or wear. Dense phase …
