A mill for producing finely divided particulate material copmrising a mill housing, a rotor adapted to rotate within the housing, an inlet for stock and an outlet for the finely divided particulate material, the rotor having at least one hammer, the hammer moves in direction of hammer travel and passes into close proximity with a miling surface to finely divide material at the milling surface during each rotation of the rotor, while during a major portion of the hammer travel the hammer is spaced away from any surface, the speed of the hammer through it's travel, position of the hammer, rotor, milling surface and relative dimensions of the hammer, rotor and milling surface being, such that during operation an air flow with the finely divided particulate material entrained therein is generated within the housing opposite the direction of hammer travel.
A mill having a rotor employing hammers moving at high speed in a housing, the housing having an inlet and an outlet, the rotor being confined within the housing to create turbulence and particle to particle collisions between particles being processed and thereby generating an air flow opposite the direction of rotation of the rotor.
A method for comminuting inorganic or organic material using a housing with an eccentric rotor in which a reverse airflow is generated to discharge from the housing finely divided particulate material entrained in the reverse airflow.
A mill for producing finely divided particulate material from larger input stock, the mill comprising a mill housing to contain the stock during processing, a rotor adapted to rotate within the housing, an inlet for stock and an outlet for the finely divided particulate material, the rotor having at least one hammer, and there being provided a milling surface, the hammer being adapted to move in a direction of hammer travel and to pass into close proximity with the milling surface to finely divide material at the milling surface during each rotation of the rotor, while during a major portion of the hammer travel the hammer is spaced away from any surface, the speed of the hammer through its travel, position of the hammer, rotor, milling surface and the relative dimensions of the hammer, rotor and milling surface, being such that during operation an air flow with the finely divided particulate material entrained therein is generated within the housing opposite the direction of hammer travel.
