ABSTRACT:
A roller mill according to this invention includes a base and a table supported on the base, the table being adapted to be rotated on a generally vertical axis. The table has an annular groove formed in its top surface, the groove having a semicircular cross section. At least one roller is supported by the base above the table, each roller being rotatable on an axis which intersects with the vertical axis of the table. Each roller has an arcuate peripheral portion which forms part of a circle of curvature in cross section. The roller and the table rotate on their respective axes, and they are adapted to compress and mill material in the groove betweem them, a clearance which receives the material being formed between the peripheral portion of the roller and the groove. The roller has a wider axial dimension on the side which is inward radially of the table from a radial plane of the roller, this plane passing through the center of the circle of the peripheral part of the roller, than the axial dimension on the outward side of the table.
