GYRATORY CRUSHER WITH ARRANGEMENT FOR RESTRICTING ROTATION

摘要

A gyratory crusher has a crushing head (22) on which a first crushing shell (30) is mounted, a frame on which a second crushing shell is mounted, and a driving device, which is arranged by means of a rotating eccentric to cause the crushing head (22) to execute a gyratory movement for crushing of material. The crushing head (22) is connected to the frame by way of a rotation-restricting arrangement (40), which comprises a beater (44) in a tank (42). Spinning of the crushing head (22) is restricted by the beater (44) being braked, during operation of the crusher, by a liquid contained in the tank (42).
