This bulk bag unloading and pneumatic conveying system, specially treated to transfer a highly corrosive, granular material, uses integrated automation to minimize human exposure to the material and optimize process efficiency. To reduce wear, the bulk material handling 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.
