摘要：
A method and apparatus for the two-stage crushing of brittle material comprising a roll mill and a second mill downstream thereof, the output of the second mill being delivered to a sifter. The quantity of grit obtained in the sifting operation is divided between the roll mill and the second mill in such a way that the sum of the quantity of fresh material and the quantity of grit delivered to the roll mill remains constant.
