Pneumatic conveying systems have the advantage of being able to accommodate various pipeline routing geometries, but the options aren’t limitless. In this article, columnists Jack Hilbert and Etienne Brochu first define a basic pneumatic conveying system and conveying modes and then discuss some conveying line geometry best practices.
For your pneumatic conveying system to work efficiently with other system components, each piece of equipment needs to be considered in relation to how it will impact the system as a whole. In this column, Jack and Julien discuss how filtration equipment and pneumatic conveying system operations can impact each other.
Columnist Jack D. Hilbert discusses how bulk density differences between two materials can affect a pneumatic conveying system's design and overall performance.
In this column, authors Jack Hilbert and Colin Barbeau provide information on the economics of pneumatic conveying with regard to how it compares with alternative forms of material conveying. Since the processes, design criteria, conditions, and technical advantages and disadvantages vary from project to project, the authors break down two different case studies as examples.
Columnist Jack D. Hilbert revisits a previously covered topic on how adding another material inlet to an already efficiently running pneumatic conveying system might affect that system.
Columnist Jack D. Hilbert follows up on Part I of his “Factors that affect pneumatic conveying” column (PBE, March 2019, p.18) in which he discusses a variety of issues that may need to be addressed when pneumatically conveying materials.
Columnist Jack Hilbert discusses the effects of temperature and moisture on pneumatic conveying system design, equipment selection, and operation.
Columnist Jack D. Hilbert, along with contributing columnist David Renfert, explain how both pneumatic conveying and nuisance dust collection systems can become problematic when adequate planning and investment don't take place up front.
Columnist Jack D. Hilbert reviews some of the velocity- and conveying-related terms that you should know to effectively manage your pneumatic conveying system.
Columnist Jack D. Hilbert explains how adding a bin vent fan to your pneumatic conveying system affects system costs and operation.
Columnist Jack Hilbert explains how to "listen" to a material.
Columnist Jack Hilbert looks at pneumatic conveying line design and explains how a variety of factors affect material flow in dilute-, two-, and dense-phase conveying.
Paul Solt was PBE's first columnist, so we take a look back at one of his early articles.
Columnist Jack D. Hilbert describes material flow problems, patterns, and properties that can ultimately affect pneumatic conveying system performance.
Columnist Jack D. Hilbert discusses the ins and outs of using flexible hose in pneumatic conveying systems.
Columnist Jack D. Hilbert discusses common causes of material buildup in pneumatic conveying lines and offers suggestions on how to avoid it.
Columnist Jack Hilbert looks at the recommended instrumentation for a conventional pressure-type, dilute-phase pneumatic conveying system.
Columnist Jack Hilbert describes a variety of feeders and how to choose the best one for your pneumatic conveying system.
Columnist Jack Hilbert reviews what cubic feet per minute (cfm) and related terms mean — exactly — when discussing gas volume and velocity in a pneumatic conveying system.
This column picks up where our last column left off, answering more questions from PBE readers.
In this column, consultants Jack D. Hilbert and Paul E. Solt answer questions from PBE readers.
The columnist continues a discussion about saving energy in pneumatic conveying, this time focusing on conveying line layout and bends, air boosters, and air-material separation equipment.
Building on the information presented in his first three series of columns, Paul E. Solt -- a private consultant with more than 41 years experience installing and troubleshooting pneumatic conveying systems -- presents a fourth series of columns on troubleshooting pneumatic conveying systems. In a separate section, Solt also answers your pneumatic conveying questions.
Pneumatic conveying systems in bulk solids plants are prime candidates for going on an energy diet. Information in this column can help you understand how various components contribute to your system's power requirements and, where possible, how to minimize these effects.
