Abstract
A device for the homogenization of material to be crushed particularly for crushing coal to uniform grain size comprises a first conveyor for feeding the material to be crushed which has an upper section and a lower section which extends downwardly away from and below the upper section. A coarse material conveyor overlies the lower section and is disposed at the level of the upper section and between it and the upper section there is a grading device which permits deflection of the fine material so that it is fed downwardly with the lower section and the transfer of the coarse material over the lower section onto a perforated crusher plate. A crushing roll is disposed above the crusher plate in a position to crush the coarse material which is fed thereon to a side operable to the material carried by the lower section and to deposit this material onto the lower section by passage through the openings of the crusher plate.
