The figure is a plan view showing the distribution of the materials to be crushed when the supply of the materials to be crushed is expanded to a certain range. The figure is a vertical cross-sectional view, Figure 4 is a plan view of the rotary table in the case where the groove has a spiral shape that lags behind the rotation direction of the rotary table as it moves toward the outer periphery, and Figure 5 is a developed cross-section of the groove. Figure 6 is an enlarged cross-sectional view of the groove to explain the force acting on the particles in the groove, and Figure 7 is a plane view of the rotary table to explain that the locus of movement of the object to be crushed is changed. FIG. 8 is a plan view of a rotary table in which the shape of the groove is spiral, leading toward the outer periphery with respect to the rotation direction of the rotary table. 11...Crusher, 14...Groove, 15...Rotary table, 19...Roller.

Claims (3)

[Scope of utility model registration request] (1) It is equipped with a rotary table and a plurality of crushing rollers that rotate with their circumferential surfaces pressed against the upper surface of the outer circumference, and the material to be crushed supplied to the center of the rotary table is crushed by rotation of the rotary table. The vertical axis moves the rotary table including the crushing roller in a spiral trajectory to the outer periphery of the rotary table to crush the material to be crushed between the rotary table and the crushing roller using centrifugal force applied against the frictional force between the rotary table and the crushing roller. The mold crusher is characterized in that a plurality of grooves are provided on the upper surface of the rotary table in a spiral shape extending from the center toward the outer periphery, and whose width and depth become smaller toward the outer periphery. Vertical crusher. (2) The vertical crusher according to claim 1, wherein the groove has a spiral shape that lags behind the rotation direction of the rotary table as it goes toward the outer periphery in plan view. (3) The vertical crusher according to claim 1, wherein the grooves have a spiral shape in a plan view that extends toward the outer periphery with respect to the rotation direction of the rotary table.
