  Therefore, it will be seen that as the high pressure fluid stream leaves the rear nozzle II and passes through the chamber 12 and intermediate nozzle 10, no back pressure will result since the natural expansion of the stream is compensated for by the increased cross-sectional area of the middle nozzle 10. In a like manner the increased diameter of the stream as it passes from the middle nozzle 10 to the front nozzle 9 is provided for by the larger opening in the front nozzle 9. A nozzle casing 5 forms the holder for the resilient discharge nozzle 9 and consists of a sleeve with a forward cut-away section of reduced diameter, an axial hole 14 through the sleeve to receive the nozzle liner 9,Non-metallic Minerals Mill an annular recess 15 to receive the flange of the nozzle liner, an internal thread 16 of larger diameter than the hole 14 that is fitted to a thread 17 of the tube 6, and an annular recess 18 near its rear end containing a rubber ring 19 that clamps against the tube 6 when sections 6 and 5 are screwed together, effectively brushing the thread free from sand and dirt. The recess 18 has one or more holes 20 extending radially outwardly from its circumference, which fit over one or more knobs 21 on the circumference of the rubber ring 19, thereby forcing the ring 19 to revolve with the sleeve 5. The discharge nozzle 9 is of substantially cylindrical section with an external annular ridge 22 near its center and a cylindrical axial hole 23 extending through it.
  
  The hole 23 is tapered outwardly and rearwardly from a point near its rear end. The discharge nozzle 9 is preferably made of rubber or other resilient material since these materials being resilient, are much more resistant to abrasion than are metals. Disposed within the recess 15 and held against the outer end of the tube 6 is the ridge 22 of the nozzle liner 9; therefore,palm kernel crushing machine, it will be seen that the nozzle liner 9 will not be forced from the gun by the projected abrasive. The wet sand is brought into the gun through a hose connection 24 which opens into the lower side of the chamber 13. Therefore, it will be seen that the course of the sand is through the hose connection 24, chamber 13 and nozzle 9 only, and since the movement of the sand is not rapid until it starts flowing through the nozzle 9, wear is largely restricted to this latter part.
  
  The middle nozzle 10 has a cut-away forward section of reduced diameter, an axial hole 25 of varying diameter, being smallest at a point somewhat forward of its center; it tapers from this point outwardly in both directions.Axially through the rear nozzle 11 is a hole 26 which tapers outwardly and forwardly from a point near the forward end of the nozzle. The external forward surface of the nozzle II tapers at 27 inwardly and forward from about the same position longitudinally that the internal taper begins. The front of the nozzle 11 is somewhat behind the rear of the nozzle 10, forming a chamber 12 between the two in the tube 4. A needle valve 38 of well known design is screwed into a threaded opening 39 leading into the 7yg chamber 12 so that by adjusting this valve 38 varying anounts of air can be allowed to flow into the chamber 12.
