  • Cooling and classifying apparatus for pelletized product processing
    Patent number: 8869988
    Abstract: A cooler for particulate product includes a substantially enclosed housing. A first cooling screen is disposed in the housing and is configured to receive the product. The first cooling screen is configured to move the product along a surface by gravity when the first cooling screen vibrated. A duct is coupled to the first cooling screen to move cooling fluid through the first cooling screen. A second cooling screen is disposed in the housing below the first screen and is configured to receive the product after discharge from the first screen. The second screen is configured to move the particulate product along a surface when vibrated. A second duct is coupled to the second screen to move cooling fluid through the screen. A collector receives the particulate product after moving along a surface of the second screen. A vibrator is coupled to the housing and vibrates the housing.
