  • Apparatus for dust control
    Patent number: 5803955
    Abstract: An apparatus for controlling dust generated during a material transfer operation includes an environmental enclosure surrounding a conveyor bed, the enclosure having a series of baffles creating scrubbing chambers in which dust particles are agglomerated by a fog or mist. The baffles have ports allowing positive airflow under the influence of the moving material and of the conveyor bed so that airborne dust particles impact and adhere to the wet baffle surface. Accumulated dust in the form of a wet sludge eventually drops onto the material on the conveyor and is carried out of the system.
    Type: Grant
    Filed: July 14, 1997
    Date of Patent: September 8, 1998
    Assignee: The Raring Corporation
    Inventor: David L. Raring
