<p>An apparatus for increasing the solids to fluids ratio of a slurry is constructed from a chamber which has a substantially circular cross section with a high pressure slurry inlet mounted through said chamber wall with the axis of the inlet normal to a diameter of the chamber. A high pressure slurry outlet is mounted through the chamber wall with the axis normal to a chamber cross section. A low pressure outlet is mounted through the chamber wall with its axis substantially aligned with the axis of the circular cross section so that a certain portion of the fluid entering the high pressure inlet will exit the low pressure outlet. The amount is contolled by a valve inserted in the low pressure outlet. The fluid is preferably of the type which operates by reducing its diameter. Anticavitation means may be provided for the chamber by passing air from the outside of the chamber into the chamber when the pressure in the chamber becomes less than the air pressure outside the chamber.</p> |
