and inert gas nozzles 16 the material to be processed is placed into the inlet hopper 12 the physical dimensions of inlet hopper 12 and the initial size of a feedstock material 50 to be processed control the rate of input of feedstock material into the inert gas aided pulverizer 10 the feedstock material 50 travels from inlet hopper 12 into inlet tube 14 inlet tube 14 is inclined from the horizontal approximately 30 u00b0 to control the rate of travel and time that the feedstock material 50 is exposed to the inert gas the inert gas enters the inlet tube 14 through inert gas nozzles 16 the source of the inert gas is not shown but may include pressurized tanks of liquefied nitrogen or a suitable equivalent the invention will now be further described using liquefied nitrogen as an exemplary source of inert gas fig3 shows a cross section of the inlet tube 14 of the inert gas aided pulverizer 10 shown in fig1 along line b b u2032 two inert gas nozzles 16 are shown penetrating inlet tube 14 each inert gas nozzle 16 is approximately 15 u00b0 from vertical as viewed in fig3 inert gas nozzles 16 allow for the flow of liquefied nitrogen.
