#2 Specification of required air volume for each point of use & dust collector, requirements to design system maintain minimum source point airflow NFPA-664-20 8.2.2.1.4 Every section of the dust collecting system must be sized for not less than the minimum air velocity and volume required to collect and transport the material through the ...

Understanding Conveying Velocities | Donaldson Industrial …

2022-6-17 · As an example, lead dust, which is relatively heavy, typically requires a minimum conveying velocity of 4,500 feet per minute, whereas weld fume, which is much lighter, may require 2,000 – 2,500 feet per minute. When conveying velocities are not sufficient to keep the material moving through the duct, the potential exists for the dust to ...

Minimum Conveying Air Velocity

The relationship between the minimum conveying air velocity and the solids loading ratio at which the materials can be conveyed is presented in Fig. 16.3.For the dilute phase conveying of the cement, a minimum conveying air velocity of 11 m/s is required, but for the potassium sulphate, it is about 14 m/s. At higher solids loading ratios the minimum conveying air velocity for the …
