National Bulk Equipment, Inc. (NBE) introduces 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 optimal output torque and motor horsepower, according to the company.
The conveyor discharge head is 12 gauge 304 stainless steel, formed and welded with continuous-weld seams ground to a No. 4 finish and hand-burnished to eliminate gaps, joints, bolts, and resulting material accumulation. NBE flexible screw materials of construction and application-specific flight designs enable sustained conveying at designed capacities of rugged materials and rigorous bulk densities.
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. NBE casings are ¼-inch thick, 11 gauge stainless steel or carbon steel. NBE flexible screw conveyor hoppers have 12 gauge 304 stainless steel walls, 10 gauge 304 stainless steel legs and 7 gauge stainless steel component stand-offs. Hopper designs have steep-slope sidewalls, sheer-drop material feed guides and a flangeless conveyor intake that draws in material and eliminates bridging, ratholing and cleaning access problems.
