March 2021 / 37 PBE FOCUS PRODUCTS Pneumatic Conveying This product summary profiles just some of the pneumatic conveying equipment available. The information reported here is furnished by the manufacturers; no product endorsement is intended. Slide-gate valve suitable for pneumatic conveying applications with pressures up to 15 psig Quantum Orifice Gate slide-gate valve is engineered to handle dry bulk solids in gravity-flow, dilute-phase, or vacuum conveying systems with pressures up to 15 psig. Valve's narrow profile and lightweight construc- tion allow for easy installation in either a vertical or horizontal orientation. Valve features full-flange, weather-resistant design; "self-cleaning" blade on the opening stroke to prevent material packing in the valve's internal seals; and hard-polymer seals that compensate for wear over time. Valve offers quick, easy shim removal for seal adjustments and inline blade adjustment. Vortex, Salina, KS 888-829-7821 www.vortexglobal.com Dilute-phase pneumatic conveying system's air velocity ranges from 4,000 to 8,000 fpm Dilute-phase pneumatic conveying system uses either pressure or vac- uum to convey powders, pellets, granules, and irregularly shaped parti- cles smaller than 20 millimeters (0.75 inches) with most materials having bulk densities between 0.1 to 1 kg/dm 3 (5 to 100 lb/ft 3 ). System's gas or air velocity can range from 4 to 40 meters per second (4,000 to 8,000 fpm) and handles a wide range of materials with different characteristics, including high bulk density, cohesive properties, or extreme particle shapes. Coperion K-Tron Salina, Salina, KS 785-825-1611 www.coperion.com Pneumatic gain-in-weight filling system conveys, weighs, discharges material into bulk bags Pneumatic gain-in-weight filling system conveys and weighs bulk materi- als and then discharges the materials into bulk bags. System is equipped with the company's Pneumati-Con pneumatic conveying system, which features a filter-receiver that's mounted on load cells to weigh incoming material. System uses the company's Twin-Centerpost bulk bag filler to inflate bags and remove creases before a slide-gate valve at the filter- receiver's outlet opens to discharge a batch of materials into a bag. System's filler check-weighs each filled bag. Flexicon, Bethlehem, PA 888-353-9426 www.flexicon.com
