IMPACT CRUSHER HAMMER

Abstract

An impact crusher hammer comprises a hammer shaft sleeve sleeved and mounted on a roll shaft of the impact crusher using a shaft hole. A cubic hammer body is connected above the hammer shaft sleeve through a journal. Both the front working surface and the top working surface of the hammer body are provided with two kinds of different sized elliptic cylindrical hard alloys that are evenly alternated. The elliptic cylindrical hard alloys are deeply embedded into and firmly welded with corresponding deep holes opened on the front working surface and the top working surface of the hammer body; a large area of hard welding rods is welded on two side surfaces of the hammer body corresponding to the front working surface and the top working surface of the hammer body.

Claims
