National Bulk Equipment Inc.'s 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 system is constructed of specially coated stainless steel tubing and components, according to the company. 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.
