As all processes vary, so does the pneumatic conveying technology used to move powders, dusty powders, and other bulk materials from source to destination. When properly defining pneumatic conveying technologies, it is important to consider the advantages and disadvantages of Dilute vs. Dense Phase Conveying, and respective Dilute Phase Positive Pressure vs. Dense Phase Positive Pressure Conveying. Equally important is the accurate definition of all components that make up the conveying system, including the heart of the system, the vacuum receiver, as well as ten important design considerations for the dust-free transport of powders and combustible dusts.
