Pneumatic Conveying of Highly Corrosive Material Requires Protection of Operator and Equipment

March 4, 2011 - PRLog -- This pneumatic conveying system, specially treated to transfer a highly corrosive, granular material, uses integrated automation to minimize human exposure to the material and to optimize process efficiency with the upstream bulk bag unloading system. To reduce wear, the pneumatic conveying system is constructed of specially coated stainless steel tubing and components; process-critical components and valves are Teflon® coated. Pneumatically conveyed material is transferred to the downstream wetting process, in batches, based on calls from weigh system sensors. Total system capacity exceeds 9,500 pounds per-hour.

NBE integrated automation centralizes system control, communication, monitoring, and reporting using NEMA 12, dust-tight enclosures, and a single, UL listed HMI, designed and built by NBE. Operator exposure to caustic material was eliminated, and operator physical ergonomics were optimized as a result of rigorous NBE risk assessment procedures. NBE expertise in specifying, designing, and manufacturing process systems to application-appropriate codes, standards, and regulations ensured system compliance at start-up.
