ABSTRACT:
A pulveriser is disclosed which comprises a fan which sucks air through a pipe. A hopper receives material which is to be pulverised, the hopper having an open lower end which communicates with the pipe. Between the hopper and the fan there is a venturi. Air flows through the venturi at a speed of Mach 1 or above. Pieces of frangible material dropped into the hopper are sucked to the venturi where they are blown apart and reduced to powder.
