In Part I of his column, Jack discussed dealing with less-than-optimum conveying air temperature and moisture content. In Part II, he discusses material explosibility, chemical reactivity, and toxicity. He also details how closed-loop conveying systems can offer advantages when dealing with these and other types of problematic materials and situations.
Factors that affect pneumatic conveying — Part II
Columnist Jack D. Hilbert follows up on Part I of his “Factors that affect pneumatic conveying” column (PBE, March 2019, p.18) in which he discusses a variety of issues that may need to be addressed when pneumatically conveying materials.
