Abstract (en)
[origin: US4732334A] 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.
