Abstract: The apparatus for feeding rolling mills, particularly for oil seed, comprises two rotatable feed rollers located in a feed mechanism housing above the rolling mill. The feed rollers are substantially vertically oriented and are rotatable in opposite directions. The housing wall running in the longitudinal direction of the feed rollers engages closely on an upwardly moving circumferential portion of the lower feed roller, in order to ensure that no material passes through in this area. All the material to be ground passes through the gap. Since the gap is formed by two feed rollers, whose surfaces move in the direction of the material, no lumps and the like collect upstream of the gap and consequently cause a non-uniform material flow. The apparatus permits a very uniform flow and simultaneously breaks up lumps.
