摘要： 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.

摘要： 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.

摘要： A vertical mill, a classifier for the mill, and a controller for the classifier. The vertical mill includes a casing having a top plate, and the classifier is adjacent the top plate. Beneath the top plate, upon which impinges an upwardly moving gas and powdery material being supplied from the lower portion of the casing, are provided a plurality of rotary blades or rotary rods which have a vertical axis of rotation. A gap is provided between the rotary blades and the top plate, and an annular impingement member is suspended from the top of the casing to outwardly surround the plurality of rotary blades in such a way as to shield the gap. Further, an opening is provided adjacent the impingement member through which a portion of the gas and powdery material pass. The controller of the classifier includes means for adjusting the opening through which the powdery material passes. A collecting device is provided for collecting powdery material from the classifier, including a detector for detecting the distribution of the particle sizes of the powdery material received by the collecting device and giving an output related to the distribution. A mechanism for adjusting the flow area of the opening in response to the output is also provided.
