ABSTRACT:
A more efficient reduction mill is described having a rotating hammer mill portion combined with a grate assembly system employing readily reversible and replaceable grate sections, including reversible and replaceable cutter bar sections forming part of the grate system. The entire grate system is mounted in a side position of discharge with respect to the axis of rotation of the hammer mill and is pivotally disengaged about a lower pivot axis by power means from the hammer mill portion. Ready access to the grate assembly for reversal or replacement of worn sections is thereby achieved. The ease of accessability to the grate assembly, combined with the ease of reversibility and/or replaceability of the various grate sections enables close spacing between the grate assembly and hammer mill to be more readily maintained thereby permitting more efficient reduction of a variety of materials, and more efficient later handling and separation of ferrous from non-ferrous materials.
