Apparatus for crushing brittle material for comminution

摘要

The invention relates to apparatus for crushing brittle material for comminution which is subjected to individual grain crushing and material bed crushing in a roll crusher at high pressure and with agglomerates being formed, these agglomerates being loosened in the sifter with the aid of a separate arrangement and removed from the crushing system. In this way a crushing stage which is provided for further crushing has its load significantly reduced and as a result the apparatus is rendered considerably more economical.
