Patent number: 11850597Abstract: Various embodiments of a hammermill system, hammer, and methods are disclosed. A hammermill hammer comprises a metal composite comprising a plurality of inserts and a body portion disposed between each of the plurality of inserts. The composition of the plurality of inserts is different than composition of the body portion. The material of the plurality of inserts has a greater abrasion resistance than the material of the body portion and the material of the body portion has a greater impact resistance than the material of the inserts. The hammers produced have improved wear resistance and longer useful life compared to conventional hammermill hammers.Type: GrantFiled: June 25, 2021Date of Patent: December 26, 2023Assignee: Postle Industries, Inc.Inventor: Robert F. Miller

Patent number: 11746605Abstract: Various methods of hardbanding an apparatus are described. In one aspect of the invention an improved method of re-applying a hardbanding alloy to worn tool joints of a previously hardbanded drill pipe results in preservation of the metallurgical properties of the drill pipe and preservation of the internal polymer coating that lines the drill pipe. A method for applying hardbanding includes arc welding a consumable metal welding wire to a tool joint having a surface temperature that ranges from about 50° F. to about 170° F. and the arc welding power supply utilizes DC current. The method herein produces a hardbanded tool joint comprising a heat affected zone (HAZ) of a based metal having a Rockwell hardness of 40 Rc or less.Type: GrantFiled: November 18, 2020Date of Patent: September 5, 2023Assignee: POSTLE INDUSTRIES, INC.Inventor: Robert F. Miller
