Abstract
High pressure liquid jets including finely divided abrasive particles suspended therein, are produced a substantial distance (e.g. from 20 m up to 100 m or more) from the liquid and particle sources by separately pumping the liquid and the particles over the distance, and then combining the two in a venturi and delivering the mixture to a nozzle. The abrasive particles are conveyed over the distance in a carrier fluid (e.g. air) which is then separated off immediately before the particles arrive at the venturi.
