  • Apparatus for generating an abrasive fluid jet
    Patent number: 4768314
    Abstract: Apparatus for generating an abrasive fluid jet comprises a feeding device (2) for continuously passing abrasive particles at a constant rate to a mixing hopper (4) in which the abrasive particles are mixed with a carrier liquid to produce a slurry of consistent concentration. A pump (10) pumps the slurry from the mixing hopper (4) to a jetting head (12) into which a high speed fluid jet is introduced in a direction substantially axially, whereby the abrasive particles are entrained in the fluid jet and ejected from the head (12) at high speed to impinge upon an object to be abrasively treated.
