Abstract (en)
[origin: US4875628A] The invention relates to a method and to apparatus for crushing brittle material for grinding using a material bed roll mill, in which at least a proportion of the branch stream returned to the roll gap is dried to such an extent that a mixed moisture content which lies below a critical moisture content is produced in the roll gap. In this way it is possible even for material for grinding which has a high moisture content and above a critical moisture value has a tendency to sticking and/or caking on to be crushed satisfactorily.
