National Bulk Equipment, Inc. (NBE) recently announced its line of application-specific flexible screw conveyors and hoppers built for harsh applications and demanding environments. NBE flexible screw conveyor gear drives and motors reportedly are specified to ensure optimal 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 and hand-burnished to eliminate gaps, joints, bolts, and resulting material accumulation.

To protect operations from the early wear of thin-wall screw casings, the conveyor has 1/4-in.-thick casings. The construction and application-specific flight designs reportedly enable sustained conveying, at designed capacities, of even the most rugged materials and rigorous bulk densities. Screw flight designs include: 3/8-in.-thick, wide-face flat or beveled flights; 3/4-in. diameter round-bar flights; or 1/2-in. square-bar flights, all available in multiple O.D., I.D., and pitch combinations.

Each standard hopper reportedly 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. The hopper designs also have steep-slope sidewalls; sheer-drop material feed guides, and a flangeless conveyor intake that draws in material and may eliminate the bridging, ratholing, and cleaning access problems associated with typical flange-style designs. The company also provides flexible screw conveyor system controls and integration, material flow devices, and multiple gear drive and motor combinations.
