A gyratory crusher, which comprises a crushing head on which a first crushing shell is mounted;

• a frame on which a second crushing shell is mounted, wherein the second crushing shell defines, together with the first crushing shell, a crushing gap;
• and a driving device, which is arranged with a rotating eccentric to cause the crushing head to execute a gyratory movement for crushing material that is introduced in the crushing gap,
• wherein the crushing head is connected to the frame by way of a rotation-restricting arrangement, which comprises a beater arranged to rotate in a tank, the tank being adapted to contain a liquid for braking the rotation of the beater.
