http://www.nbe-inc.com/dcd This fully automated, self-contained, container dumper and bulk material mixing system blends a combination of five, highly caustic, free flowing powdered additives with a sluggish flowing, high dusting base ingredient. The base ingredient is automatically introduced into the bulk packaging operation from a single, 64 cubic-foot surge hopper that feeds either of two horizontal screw conveyors; depending on the blend recipe and the material requirements of downstream packaging operations. The caustic, free flowing additives; previously manually added to the process, are input to the system using five, NBE Lift-and-Seal™ drum dumper units.
