Screw conveyor systems equal to extreme duty

Citing a marketplace void for process-critical models, the manufacturer has introduced a line of flexible screw conveyors and hoppers designed for harsh applications and demanding environments.65-IN-NBE-200

NBE flexible screw conveyor gear drives and motors are specified to ensure optimal output torque and motor horsepower—a combination bringing optimal power and conveying efficiency to the application. The conveyor discharge head is 12 gauge 304 stainless steel, formed with continuous-weld seams ground to a No. 4 finish and hand-burnished to eliminate the gaps, joints, bolts, and resulting material accumulation common with standard alternatives’ bolt-together, sheet metal construction.

Flexible screws are engineered with materials and flights enabling sustained conveying, at designed capacities, of even the most rugged materials and rigorous bulk densities. Models 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 outside or inside diameter and pitch combinations. To protect crucial operations from the early wear of thin-wall screw casings, NBE 1/4-in. thick casings are twice the thickness of typical alternatives.

NBE 11 gauge stainless steel or carbon steel casings ensure confident operation, product engineers contend. Flexible screw conveyor hoppers are built to specifications that will withstand tough duty cycles: Each standard model has 12 gauge 304 stainless steel walls; 10 gauge 304 stainless steel legs; and 7 gauge stainless steel component standoffs 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. — National Bulk Equipment, Holland, Mich., 616/399-2220;
