To provide a crusher that can feed a liquid to meet a requirement to smoothly discharge, out of a disk, a moisture-containing crushed material, although in spite that when a moisture-containing material to be crushed is crushed, the crushed material stays in the disk and is hardly discharged out of the disk, the material to be crushed is continuously charged to result in clogging.

The crusher having a sprinkling function includes a first means having: a fixed upper disk; a rotating lower disk; and drive means rotating the lower disk, and a sprinkling means, for feeding a liquid into a charge port installed on the upper disk.
