Abstract
In order to limit the dispersion into the air of fines during the processing, handling and transport of fines-containing material, a hollow plow-like member is employed to insert the fines onto a conveyor belt well below larger particulate matter being conveyed by the belt. The plow-like member has a generally narrow V-shaped cross section, and the sidewalls flare outwardly at its lower terminus. The plow-like member is positioned just above the belt surface and is oriented with its leading edge facing the direction of material flow. Thus, the larger particulate matter lumps are lifted and folded back from each side of the plow-like member's centerline to define a space into which fines can be inserted through the tool interior. After the larger particulate matter lumps pass the member trailing edge, they fall back toward the belt center and cover the deposited fines.
