How Well Do You Know Your Dust?
Author: Camfil Farr
Posted: 03/16/2010
The collection and testing of dust samples is a long-established practice used by many powder and bulk processors to make informed dust collection decisions. Dust testing protocols have not changed markedly in recent years. The importance of dust testing, however, has changed, and the implications are significant. While knowing your dust has always been good practice, it is rapidly becoming a necessity in today's regulatory climate.

This article will review two separate types of testing: (1) explosibility testing, which is used to determine whether a dust is combustible; and (2) bench testing, which pinpoints numerous physical properties of the dust. Both categories of tests are needed to determine the best dust collection system for your application and whether explosion venting equipment must be part of that system.

Chemical Processing Special Report: Conveyors
Author: Hapman
Posted: 04/20/2009
No matter what industry you’re in, chances are you use some form of conveying. Whether it be pneumatic, flexible screw, aeromechanical or other, different conveyors are required to handle different products. But which conveyor is best suited for your operation? Despite the fact that conveyors have been around for almost a hundred years, this question still baffles many industries. In order to choose the right conveyor for your operations, you need to consider your conveyor's use - production, processing, packaging, and you need to consider your business objectives - improve operations? reduce labor?

In this special report, we look at the different types of conveyors, discuss the use of tubular bag conveyors, and provide 10 tips to prevent a variety of common problems that could occur with pneumatic conveyors.

Dust Explosion Protection using Flameless Venting
Author: Fike Corporation
Posted: 11/03/2008
This 18-page white paper explores a new option – flameless venting – which has recently been developed for dust explosions and is being actively marketed as an alternative to vent ducting.

Particle Image Understanding – A Primer
Author: Lew Brown, Fluid Imaging Technologies
Posted: 09/03/2008
This paper will discuss the use of pattern recognition techniques to identify and differentiate different particle types contained in a heterogeneous solution. This application involves imaging the microscopic particles in real-time as they flow in a solution, segregating each individual particle as a separate image, and then applying pattern recognition techniques to differentiate the individual particle types.A framework for discussing the complexity of a pattern recognition operation in this application will be proposed, along with some specific examples showing how this framework applies.
