Fluidized beds offer excellent heat transfer, and have the unique ability to move a wide range of solid particles in a fluid-like fashion. This article explains the basics of fluidization theory and outlines how to design a typical fluidized bed.
Understanding the mechanisms behind caking, identifying key process variables and product specifications, and testing samples to predict the increase in cohesive strength of a powder over time are key to preventing and solving caking problems.
The WCPT8 will be held in conjunction with the 2018 AIChE Spring Meeting and will focus on all aspects of particle technology. On behalf of AIChE and the Particle Technology Forum (PTF), we invite you to participate, learn, teach and collaborate.
Before choosing a bin and hopper for your bulk solids application, the flow properties and characteristics of the powder or bulk material must be known. Use this ten-step approach to determine the optimal bin design for your process.
Powder blend consistency can be difficult to maintain during processing. This article provides an overview of common segregation mechanisms, highlights key sampling techniques, and offers practical guidance on preventing and solving segregation...
This effective approach to flowmeter selection involves a step-by-step method that begins by matching the application with the flowmeter(s). Then, a series of criteria are applied to narrow the selection.
The right elbow can keep your system operating at peak performance, reduce maintenance costs, and minimize material attrition and elbow wear. This article describes common elbows and outlines factors to consider when selecting one.

A sound theoretical model of the process to be scaled is the best approach; if one is not available, bench-scale testing, physical scale modeling or full-scale modeling is required. Here are guidelines as to which method is appropriate for various...
Agitator power consumption can be minimized by judicious equipment selection and careful operating procedures. Follow these guidelines to reduce your plant’s energy costs. In some cases, it may be as simple as flipping a switch.
To select the proper instrument for process monitoring, one must determine what attribute of the particle system impacts the process or product parameter of concern. Once the size region is identified, it can be tracked in-process, opening up the...
