  • the upper grate with its outer longitudinal sides and broad sides is loosely on corresponding portions of the housing of the hammer crusher. Since the top grate is a wearing part, it must be replaced regularly.
  • the upper part of the hammer mill is unfolded in order to provide access to the upper grate. It can happen that the top grate is lifted / shifted at least over a certain distance and then falls uncontrollably back into the hammer mill. This has two main causes:
