This invention deals generally with gyratory crushers, and more specifically with a gyratory crusher for which all regular service and parts replacement can be accomplished from above the crusher.Get A Quote
Gyratory crushers are well established machines that are used for crushing rocks, ore, and other materials. They are very large and their basic structure comprises a bowl shaped as a cone with the wider end of the cone near the top of the crusher. A conical head assembly is located on the axis of the bowl, and the head assembly is oriented so that its smaller dimension is at the top of the crusher. To perform the crushing action, independent motions are applied to the conical head assembly. The first is rotation and the second is gyration.
It would be very beneficial to have a gyratory crusher that did not require access below the machine for scheduled and emergency service of the hydraulic support assembly and for removal of the eccentric drive, and other equipment.
The hydraulic assembly, comprising the cylindrical support and piston assembly, is located below the crusher and constructed with a tight fit and seal. The piston assembly fits within the cylindrical support and can be removed from within the cylinder support. The piston assembly can be removed with the eccentric assembly in place or with the eccentric assembly first removed.
The combination of service access from the top of the crusher and all the designed wear parts on only one piston assembly thus provides an apparatus which is both exceptionally safe and very efficient to service.
FIG. 1 is a partial cross section view of the preferred embodiment of the gyratory crusher of the invention.
FIG. 2 is a partial cross section view of the lower portion of the gyratory crusher of the invention showing the eccentric assembly being removed and the hydraulic support installed in its working location.
Primary SUPERIOR gyratory crushers Wear parts. Primary SUPERIOR gyratory crushers Wear parts. A gyratory crusher consists of a concave surface and a conical head both surfaces are typically lined with manganese steel The top of the shaft attached to the crushing cone is supported centrally in the bushings and the bottom of the shaft is positioned in an eccentric bushing The feed material is.
Mainshaft 34 of head assembly 16 fits into and is attached to eccentric assembly 28, and, at the top of crusher 10, mainshaft 34 is located by bushings or bearings within spider 36, which is the upper support member of crusher 10. Eccentric assembly and mainshaft 34 are supported from below eccentric assembly 28 by hydraulic support assembly 49, which is discussed with the following details of the present invention.

The lubrication of Gyratory crushers may be one of the special problems that the Jaw crusher isnt as readily exposed to. This crusher, because it may be loaded from two sides, often is used in an open pit situation where large ore carriers are dumping directly into the crusher. This means that the machinery is exposed to whatever climate it is being operated in.

Mar 01, 2013 This can result in the adjusting piston resting against the bottom of the cylinder and the crusher setting being much tighter than the crusher is designed to operate. This situation can lead to crusher stall outs and premature failure of the eccentric bushing. 10.Unapproved modifications.

Anyway, I was wondering if anyone can assist with failure modes of Gyratory Crushers. The model we have on site is a KB 63 - 89. We had a failure recently during commision and its difficult to say what is the root cause. What we can see physically is extensive damage on the outer bushing and minor damage on the inner bushing of the eccentric.
