Abstract
A roller mill according to this invention includes a table adapted to be rotatably driven on a substantially vertical axis. The table is adapted to receive the material to be milled in a central area around the axis. The table has a substantially horizontal upper surface, and an annular groove is formed in the upper surface radially outwardly from the central area. The groove has a curved bottom surface. A least one roller is provided having an axis of rotation which is above the upper surface of the table and substantially intersects the table axis. The roller extends into and rolls in the groove and has an outer peripheral surface which is curved in cross section. The mill when in use has the table and the roller rotated, and the material extends into a clearance space formed between the peripheral surface of the roller and the bottom surface of the groove. The table has an annular overhang on the upper surface thereof adjacent the outer periphery of the groove to throttle the movement of the material out of the clearance space.
