FAQ

Frequently Asked Questions (FAQs)

  1. What material properties are required for input?
    • For precise calculations, essential properties include particle size, bulk density, and material type. Each has a significant effect on conveying behavior.
  2. How do ambient temperature and humidity impact the calculations?
    • Variations in ambient conditions can influence the properties of the conveying air and, in certain situations, the material being conveyed. Taking these factors into account is crucial, especially for specific environments.
  3. How should I account for varying system layouts and bends in the pipeline?
    • The complexities of system layouts, especially the presence of bends, introduce additional resistance. The calculator considers these components when you provide the corresponding details.
  4. Is it necessary to adjust calculations based on altitude or atmospheric pressure?
    • Altitude variations can change air density, affecting the conveying process. If operating in areas with notable altitude differences, adjusting for this is key.

Common Mistakes in Pneumatic Conveying Calculations

  1. Overlooking Air Velocity:
    • Neglecting to consider the appropriate air velocity can lead to issues like pipeline blockage or excessive wear due to high-speed abrasive materials.
  2. Assuming Material Properties:
    • Generalizing or approximating material properties, rather than using specific values, often results in suboptimal system performance.
  3. Ignoring System Wear and Tear:
    • Over time, system components wear out, altering the dynamics of conveying. Regular recalculations and maintenance checks are essential.
  4. Miscalculating Pressure Drops:
    • Incorrectly calculating pressure drops across the system, especially in more complex layouts, can lead to inefficient system performance.
  5. Not Factoring in Ambient Conditions:
    • Overlooking ambient temperature and humidity variations can skew results, particularly when conveying hygroscopic materials.
  6. Neglecting Filter/Airlock Considerations:
    • These components play a pivotal role in system performance. Overlooking their specifications or not regularly maintaining them can lead to miscalculations and reduced efficiency.
