Fig. 2 shows a view of the damaged areas of an austenitic manganese steel shredder hammer. As observed, the failure of hammer usually occurs in two areas around the hammer hole (Zone A) and the outer surface of the hammer (Zone B) [10]. The failure in Zone A is often fractured and the failure at Zone B is wearing.

Hammer crusher is also called hammer mill, or hammer mill crusher. It is a crusher that uses a series of rotating hammers to crush materials (600-1, 800 mm) into smaller pieces (below 25 or 25 mm). The hammer crusher is very suitable for medium and fine crushing of medium-hard and brittle materials. It is known for providing greater crushing ...
