  • Method and apparatus for the continuous extrusion of block elements
    Patent number: 5976432
    Abstract: A method and apparatus is provided for the continuous extrusion of porous activated carbon block filter elements. The invention includes feeding material into the barrel of a screw extruder and heating the material therein such that the material becomes an agglomerated mass. The agglomerated mass is agitated and compacted into a die where it is cooled to a semi-solidified state. In the semi-solidified state, the material is passed through a cooling tunnel where the material solidifies and the carbon block filter element is formed. A back pressure control device is also included to control pressure in the die.
