ABSTRACT:
A hammer mill having a rotor carrying a series of hammers for the reduction of material entering the hammer mill, a casing forming a material receiving inlet opening into a throat space from outside the mill, a rotor having hammers traveling in a circular path below the material inlet, the rotor being free to rotate clockwise and counter clockwise, breaker plates positioned one on each side of the material receiving throat space, and having upper and lower end portions, first adjustment provisions operably connected to the upper portions of each of said breaker plates in position for moving said breaker plate upper portions in toward or away from said throat space, second adjustment provisions operably connected to the lower portions of each of said breaker plates for positioning the lower portion of said breaker plates in a selected position relative to the hammer circular path, and said first and second adjustment means acting to support the respective breaker plate to which each is connected and effecting redirection of the material to promote a down draft to draw especially light weight particulates into the grinding rotor so the recirculation energizes the continuation of the down draft.
