ABSTRACT:
A hammermill for singulating cellulosic fibers from a pulp sheet comprises a cylindrical housing, a feed slot with a breaker bar positioned therein and a rotor mounted for rotation in the housing. Feed rolls are provided to feed a sheet of pulp into the feed slot upstream of the breaker bar. A plurality of hammers are mounted on the rotor. Air is introduced into the hammermill housing tangentially downstream from the second feed slot. An air outlet is positioned tangentially on the housing downstream from the air inlet to allow air and singulated fibers to escape.
