Patent ID: 7658341

Claim:
A flow-through dispersion device for the dispersion of aggregates, the device comprising an upstream inlet at one extremity of a conduit, at least two obstacles having opposing surfaces, said obstacles being a first or upstream inlet obstacle disposed within the conduit, said upstream inlet obstacle being perforated by at least one traversing hole and obstructing from about 50% to about 99.9% of the internal cross-sectional area of the conduit, a second or downstream outlet obstacle disposed within the conduit and a downstream outlet obstacle being perforated by at least one traversing hole and obstructing from about 50% to about 99.9% of the internal cross-sectional area of the conduit, wherein the longitudinal axis of any traversing hole of either obstacle does not align with the longitudinal axis of any other hole of a preceding or succeeding obstacle, a turbulence chamber defined by the opposing surfaces of the first and second obstacles and the inner wall of the conduit between said obstacles, and wherein the distance between two successive obstacles is from about 0.1 to about 10 times the diameter of the smallest hole of either of two successive obstacles, and a downstream outlet at the opposing extremity of the conduit.
