ABSTRACT:
A self-cleaning system and method for dispersing aggregates in a fluid medium is provided. The system is comprised of first and second members operatively associated to form an internal chamber and having an inlet to the chamber for admitting the fluid to be treated. At least one of the members is biased toward the other whereby the introduction of a fluid medium to be treated into the chamber under an operating pressure in the range of from about 50 to about 1,000 psid (3.5 to 70.3 kg/cm.sup.2) provides an elongated orifice between the first and second members having a transverse dimension or width of from about 1 to about 1,500 micrometers for egress of the fluid medium. As the fluid passes through the elongated orifice, aggregates contained therein are dispersed. The system is self-cleaning by virtue of the biased nature of at least one of the members toward the other, thereby providing longer onstream operation and requiring less servicing. The system can be used for treating aggregate-containing fluids such as oil well completion fluids, dispersions used in the manufacture of magnetic tape, and dispersion of particulates such as carbon black and other pigments.
