at transfer points.” The transfer chutes employ special ge-ometries that capture and concentrate the material stream as it travels through. Each unit is customized to suit the specific ma-terial characteristics and conveyor systems of the individual customer. They provide the dual benefits of minimizing aeration and preventing buildup within the chute, which are particularly important when dealing with combustible materials. The installation team also placed electric rotary vibrators in key locations inside drop chutes to reduce the potential for plugging. To further ensure control of fugitive material, settling zones were cre-ated at the transfer points to slow the air speed, with dust curtains to contain air-borne particles. Finally, skirtboard sealing systems were installed on the sides of the loading zones to contain dust, eliminate spillage and re-duce cleanup. With the modifications in place, HPU reports significant reductions in spillage and airborne dust. “We’re very pleased with the results we’ve seen in fugitive ma-@aZZaf_HmZda[Mladala]k[mjj]fldqhjg\m[]kYZgml+(($(((EO`gmjkg^]d][lja[alqh]jq]Yj$YhhjgpaeYl]dq/(d;g^al^jge ZageYkk$oal`Yfgn]jYdd_gYdg^/-d;& terial control,” Myers concluded. “We’re now reviewing several other conveyor sections to determine the oppor-tunities for additional dust control mea-sures. Our goal has always been to provide the Hibbing area with safe, reliable power that’s produced and delivered in an envi-ronmentally responsible manner, and this work is a reflection of that commitment.” Founded in 1944, Martin Engineering is the world leader in making bulk materi-als handling cleaner, safer and more pro-ductive.
