Abstract
A roll mill, particularly a flaking mill, for milling particulate material comprises at least two rollers, especially a stationary roller and a movable one, pressed against each other by means of a pressure exerting device. Product is supplied in a width greater than the axial width of the rollers and their nip. Channels are arranged on both lateral ends of the rollers and collect the material fed in excess of the axial length of the rollers, said channels being preferably open towards the rollers, especially over their whole length. Each of said channels discharges onto a guide surface situated above the nip of the rollers and discharges in turn all the material from the channels into the nip above the upper gripping zone of the nip.
