Title:
ROTATING CRUSHER
Document Type and Number:
Japanese Patent JP2735767
Kind Code:
B2
Abstract:
PURPOSE: To support a concave from above and allow a slack generated by continuous crushing action to be clamped more tightly and corrected by a crushing reaction in a self-control manner.
CONSTITUTION: Support levers 8 with a base end part clamped by a tightening bolt 9 are arranged on the inner top of a concave support part 3b, in the upper barrel 3 of a dual cylindrical structure having the concave support part 3b engaged with the interior of a fixed barrel part 3a. On the other hand, an annular collar is arranged on the upper outer periphery of the concave, and a gradient ring 10 having gradient projecting parts 10a with an inclined surface which is gradient downward in the rotating direction of a mantle 7 on the lower surface, allowed to protrude in a peripheral direction, is attached to the lower surface of the annular collar 7a of the concave 7 in one piece. Further, the tip of the support lever 8 is allowed to engage itself with the lower surface of the gradient projecting part 10a. Thus the concave 7 is retained in the concave support part 3b of the upper barrel 3.
