ABSTRACT:
A method and apparatus for the continuous extrusion of composite solid articles from feed mixtures comprising a substantially uniform mixture of particulate binder material and particulate primary material in which the feed mixture is forced through an extrusion die of substantially uniform cross-section and subject to heat, pressure and cooling which consolidates the feed mixture whereby it emerges from the die as a solid composite article and in which the pressure in the extrusion die is supplied by back-pressuring means external of the die. Solid filter elements of activated carbon particles for a wide variety of filtering applications may be formed using the process and apparatus.
