ABSTRACT:
The invention relates to a method and apparatus for the comminution of brittle material for grinding, particularly send-like material such as metallurgical sand in the roller gap of a material bed roller mill. In order to create an optimum capacity for drawing in the material for grinding in the roller gap, the material for grinding at the inlet to the roller gap is set to a (mixed) moisture content of approximately 0.3 to 3.0%, preferably approximately 0.5 to 2.0%.
