Abstract
Apparatus and method for removing dust from particulate material, utilizing a tower or column having a passage with a series of baffles on opposite sides over which the particulate material cascades while air is drawn across the flow path of the material to remove the dust dispersed in the material and adhering to the surface of the particles of material. Air is drawn across the passage from one side to the other by vacuum or suction from a vacuum pump or the like. In performing the method using the apparatus, the particulate material is introduced at the top of the column and permitted to cascade down through the vertical passage therein from one baffle to the next, and air is drawn inwardly between the baffles on one side and outwardly between the baffles on the opposite side of the column, and, as the air flows through the material cascading between the baffles, it removes the dust from the material. The apparatus can be used in conjunction with a storage bin, or with a conveyor which removes the material as it is discharged by the apparatus.
