To enhance fine crushing capacity and to extend the life of a concave liner.
If the radius R of curvature of the crushing zone 1a of the concave liner 1 of a cone crusher equipped with the concave liner 1 and the hollow truncated cone-shaped mantle liner 2 revolverd and shaken inside the concave liner 1 is set 1.4-1.6 times the crushing surface length L of the mantle liner 2, it is unnecessary to narrow a charging opening to a degree obstructing the smooth charging of an object to be crushed and the effective crushing region of high crushing surface pressure contributing to the crushing of the object to be crushed becomes wide and, since this wide effective crushing region is equally abraded, the fine crushing capacity of the object to be crushed is enhanced and the life of the concave liner 1 can be extended.
