<p>The conveyor (100) has a movable web (2) without a free end for transporting a pulverulent material. A containment system (8) is arranged for allowing the pulverulent material to be transported by the movable web. A set of frames (16a, 18, 19) is arranged to support the containment system. An air treatment system (110) is connected to the containment system for extracting air from the containment system and producing vacuum-cleaned air. A major part of weight i.e. above 90 percent of weight, of the air treatment system is taken by the frames.</p> |
