Abstract

The disc roller mill has a squeezing unit for squeezing granular feed raw material. The squeezing unit has two parallel rotatable disc rollers (68a, 68b), between which there is a gap, wherein the feed raw material to be squeezed can be led. The disc rollers have an axis (70a, 70b) and a number of discs (80) fitted around the axis. The discs have an inner part (84) in the direction of the normal to the surface of the axis and an outer edge (88). Between the inner part and the outer edge there is a squeezing surface (86), which substantially has the shape of a cut-off cone. The squeezing surface of the discs can be substantially smooth or it can have grooves substantially in the direction of the radius of the disc.
