Problems solved by technology

The problem with this type of gyratory crusher is that when no material is being fed to the crusher, the crushing head will eventually start to rotate with the eccentric, this is commonly known as autorotation
[0004] Hydraulic pumps provided with anti-backflow devices are complex and tend to break or become clogged with dirt, which will cause undesired downtime

Embodiment Construction

[0023] figure 1 A gyratory crusher 10 is schematically shown having a frame 12 including a frame bottom 14 and a frame top 16 . A vertical center shaft 18 is fixedly attached to the frame bottom 14 of the frame 12 . The eccentric 20 is arranged rotatably about the central axis 18 . The crushing head 22 is rotatably mounted about the eccentric 20 and thus about the central axis 18 . The drive shaft 24 is arranged such that the eccentric 20 is rotated about the central axis 18 by means of a bevel gear 26 meshing with a ring gear 28 connected to the eccentric 20 . Such as figure 1 As shown and known per se from the prior art, the outer circumference of the eccentric 20 is slightly inclined with respect to the vertical plane. Due to the inclination of the periphery of the eccentric 20, the crushing head 22 will also be slightly inclined with respect to the vertical plane. figure 1 The crusher 10 shown is of a version without top bearings.

Abstract

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 device 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).

Description

technical field [0001] The invention relates to a device for limiting spinning in a gyratory crusher comprising: a crushing head on which a first crushing shell is mounted; a frame on which a second crushing shell is mounted Mounted on this frame, the second crushing shell defines the crushing gap together with the first crushing shell; and the drive means, which is arranged to cause the crushing head to perform a rotary movement through the eccentric device, so as to crush the material introduced into the crushing gap Material. Background technique [0002] Gyratory crushers of the type described above can be used, for example, to break ore and rock material into smaller sizes. The problem associated with this type of gyratory crusher is that when no material is being fed to the crusher, the crushing head will eventually start to rotate with the eccentric, this is commonly referred to as autorotation. If the crushing head is spinning when the feed material is reintroduced...
