Abstract: An improved hammer mill hammer constructed by forming a groove in an edge of the grinding end of a hammer for receiving hard facing material and placing hard facing in the groove.

Abstract: An improved hammermill hammer with a connection end having a bearing race in the hammer body and a bearing received in said bearing race, the bearing having a non-circular, elongated, elliptical, oval or egg shaped inner bearing surface for receiving a hammer rod there through to prevent the hammer from sticking to the hammer rod.

Abstract: A method of providing for a manually insertable bushing in a spherical joint. By forming slots, strategically located and sized, the bushing may be inserted manually into the race, then rotated into position in the race. The bushing may be disallowed from exiting via the slots by engaging the bushing to a shaft, or by a keeper affixed to cover the slots.

Abstract: The present invention provides a process and product for applying a hard coating to corrugated roller shells, and other roller shells having an irregular outer contact surface with raised portions. The roller, together with the welding electrode and associated particle feeder are movably attached to a fixture that allows them to move with respect to each other. The electrode is positioned at a starting location, actuated to form a weld puddle into which the particles are fed, and moved along an application path that follows the raised portions.

Abstract: Hammers, including hammer blades, for hammer mills are shown which have an insert bushing press fit into a hole in each hammer blade so that the hammer blades rotate with the bushing around rods being rotated in a circle around a central rotary axis of the rotor of a hammer mill.

Abstract: A method of avoiding hammer rod-hole deformation in a hammer mill. Conventional hammers are fitted with a bearing structure that reduces wear while permitting the hammer to pivot about multiple axes. An optional, integral spacer provides spacing between adjacent hammers.
