Abstract (en)

[origin: EP0238147A1] In an extrusion mill of the type of a pellet press, there are pressing rollers 7 rotating within a perforated drum 3 for pressing material through the openings in the drum e.g. for making pellets for feeding cattle. The invention relates to the adjustment of the rollers radially with respect to the drum during operation, by adjustment means extending to the outside opposite the side where the material to be pressed enters the drum. The rollers are first adjusted in positions close to the drum wall and are then gradually adjusted inwardly during pressing, to give better results, prevent clogging of the mill with tacky material therein and avoid the necessity to stop the mill and open it for each adjustment.
