Crusher head for rigid-hammer crushers

摘要

The crusher head (1) used for rigid-hammer crushers has a lower part which is constructed in a fork shape and into which a crusher arm (2) engages and is held there by a bolt (5). The bolt (5) is secured by means of a securing pin (7) which is guided through an axial bore in the bolt (5) and is bent over at the ends. The front face, in the direction of rotation of the rigid-hammer crusher, of the crusher head (1) is closed and curved forwards between the fork-shaped legs (4). A bead (6) of predetermined height is formed onto the rear of the crusher head (1) in the softer part. <IMAGE>
