  • Powder Processing Best Practices

    A material’s characteristics and how they may change during processing can affect HOW these materials are processed. Key factors affecting powders include aeration, moisture absorption, electrostatic charging to name a few. Many bulk solids are sensitive to heat and humidity. As these levels rise, either in the feeder system or via outside conditions, flow problems crop up. As the powder gains strength, jams and poor flow conditions begin to appear. Costly downtime and a loss of product are incurred while a search is made for a solution to the flow problems. In this Chemical Processing Powder eHandbook, we take a look at key factors affecting powders and today’s best practices for overcoming the processing of powders including:
     

    • Looking beyond the physical properties of particles and treating powder as a bulk entity
    • How scanners take volume to a new level - acoustics-based sensors can help accurately measure the volume of powders in vessels
    • How to determine a coating’s volatile content  - advancements in rapid loss-on-drying techniques significantly reduce testing time
    • Testing powder flow - advances in test methods help better predict flow behavior at elevated temperature and humidity levels

  • Understanding Dust Explosion Dangers

    The unfortunate propensity of dust explosions to destroy entire facilities and claim lives is very real. Powder handling processes often are comprised of interconnected enclosures and equipment. Flame and pressure resulting from a dust explosion can therefore propagate through piping, across galleries, and reach other pieces of equipment or enclosures, leading to extensive damage. In this Chemical Processing Special Report, we take a look at the latest NFPA standards and dust explosion mitigation strategies. This Special Report covers:
     

    • Significant revisions to dust explosion standards – NFPA 654 major changes include new administrative requirements
    • How to defuse dust dangers - carefully consider and then counter risks of fire and explosion
    • Five common dust explosion misconceptions that can lead to a false sense of security

  • Powder eHandbook: Efficient Powder Process Handling

    The mechanisms of powder flow are complex. They are influenced by an array of different parameters; some relate to the particles’ physical attributes, such as size and shape, and others, such as humidity, to the system itself. Although there is a general understanding of these individual mechanisms, the multitude of interactions that govern the specific behavior of a given powder can many and in turn, affect how these powders are processed.
