Abstract

B2H and B2P. A jet pulverizer comprises a material injector nozzle arrangement I, Fig. 1 which also effects initial comminution, and a mill chamber MC including tangential high-pressure fluid jets 9 which may be plain or of the venturi type. The injector I comprises an input jet tapering at 1a and expanding at 1c, and leading into a nozzle 2 tapering at 2a and expanding at 2c. Material to be ground is supplied tangentially at 4. The material is thence fed to the mill chamber MC via an annular manifold 13 and inlets 15. The mill chamber may be of pan, toroidal "race-track" or serpentine form, of circular square or trapezoidal cross-section. The system may include a cyclone and provide for recirculation of the product by means of an adjustable scoop 34, Fig. 6, and mills may be arranged in parallel with commoned outlets. A system includes a cyclone collector 42, Fig. 8, jacketted at 44. Fine particles enter the collector 42 and water droplets in a spray 52 sweep them up. The droplets are immediately evaporated by the jacketted walls and later condenses in a condenser 55. In an alternative system gas leaving the grinding system is supplied first to a nozzle 59, Fig. 10 and then via an adjustable nozzle 60 is turned downwards by an impact plate 61 and thence passes upwards via adjustable shutters 62. Particles of a precisely desired size may be bled off by adjustment of the nozzle and shutters. Substances referred to, which may be ground in the apparatus include tea leaves, pigments, fuels and soil nutrients. (For Figures see next page)
