Macawber Engineering, Inc. has installed tens of thousands of pneumatic conveying systems worldwide. We have over 35 years experience designing these systems for wide variety of bulk materials. We specialize in the design and engineering of lowvelocity, densephase pneumatic conveying systems.

17/09/2013· Dense Phase The basic concept of Dense Phase Conveying is that a pulse of air is used to force a plug of material from one point to another. The air has high pressure and low velocity. It is ideal for Higher density products or conveying longer distances. Dense phase is the best option for abrasive pre blended products.

Compared with dense phase, friction between the pipe and the solids (Item 6) in dilute phase conveying is usually negligible and it can be ignored. 2. Calculation Method • Design of new systems. In their book published in 1960, ZENZ and OTHMER give the following two equations for calculating pressure drop in dilute phase conveying systems:

A pneumatic conveying system is efficient and inherently dusttight, making it the most practical ... A densephase system has a low airtomaterial ratio. The

1. Basis for the Calculation Method The calculations for the design of a dilute phase conveying system are based on determining the pressure drop that is generated 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:

Typically, our pneumatic conveying systems in dilute phase are designed to transfer approximately 6 kilograms of product per kilogram of dry bulk conveying air. iii. The diameter of the pneumatic conveying line is adjusted to this concentration ratio of powder / air and the pressure drop that will be generated by the operation of the system.

The second category, high pressure systems, are known as dense phase systems. These systems utilize air pressure above 15 psig (up to 50 psig) in the pipe and use positive pressure to push materials through the conveying line at relatively low velocities (from 100 fpm to a maximum of 1000 fpm) much like extruding.
