ABSTRACT:
An improvement to a hammermill extends the life of the hammers by providing regular and periodic reversal of the rotor of the hammermill without the necessity of disassembly of the hammermill or the necessity of moving or operating levers, screws or other devices in order to reposition the internal apparatus so that the mill can be reversed.
The improvement consists of an internal apparatus attached to the hammermill at the inlet to the hammermill. The internal apparatus is formed of a vertical plate extending adjacent the inlet and attached to a mounting plate. The mounting plate is bolted to the hammermill. The vertical plate extends across the width of the hammermill. A plurality of triangular reenforcement plates are welded between the vertical plate and the mounting plate. The mounting plate can have its free edge bent toward the inner wall of the hammermill to insure a tight seal with the inner wall. Hard-facing can be formed along the exposed end of the vertically extending plate and the free edge of the mounting plate to substantially extend the life of the assembly. Two such assemblies are mounted inside the hammermill, one on each side of the inlet and extending across the width of the mill.
