SUMMARY OF THE INVENTION
A primary object of the present invention is to provide a hammer mill in which there is a series of double headed hammers which are brought into operation without shutting down the hammer mill.
Another object of the present invention is to provide a hammer mill having double headed hammers in which the heads are brought into shredding operation without remounting of the hammers.
A further object of the present invention is to provide an improved type of hammer having two heads in which both are brought into shredding operation during continuous operation of the machine.
The above objects of the invention are achieved by providing a hammer having two heads and in which the hammer is mounted to pivot on its central axis with the two heads being available for shredding during operation of the machine. Thus as a hammer head is worn, centrifugal force will bring the other less worn head into operative position. Further, during normal operation of the hammer mill both heads of the hammer, because of the central mounting, will serve to shred the items.
