National Bulk Equipment Inc. (NBE) offers a line of application-specific flexible screw conveyors and hoppers built for harsh applications and demanding environments. NBE flexible screw conveyor gear drives and motors are specified to ensure output torque and motor horsepower. The conveyor discharge head is 12 gauge 304 stainless steel, formed and welded with continuous-weld seams that are ground to a No. 4 finish and hand-burnished to eliminate the gaps, joints and bolts.
Screw flight designs include: 3/8-inch thick, wide-face flat or beveled flights; 3/4-inch diameter round-bar flights; or 1/2-inch square-bar flights all available in multiple O.D., I.D., and pitch combinations. Each NBE flexible screw conveyor hoppers has 12 gauge 304 stainless steel walls; 10 gauge 304 stainless steel legs; and 7 gauge stainless steel component stand-offs for long-term performance assurance. NBE hopper designs also have steep-slope sidewalls; sheer-drop material feed guides, and a flangeless conveyor intake that draws in material and eliminates the bridging, ratholing, and cleaning access problems associated with typical flange-style designs.
