Hydraulic gyratory crusher:PXZ
CITIC HMC manufacture a range or Primary Gyratory Crushers to suit both the Mining and Aggregate Industries with an installed based operating since 1997.
The basic concept behind the Gyratory Crusher remains the same as it did during its inception, but the machine is entirely updated to address today’s advanced technology, safety concerns, and operation schedules.
Our focus is on continually improving the design of our equipment to better serve our customers.
CITIC offers custom engineered solutions as an answer to our customers’ unique requests.

Since the gyratory crushes on full cycle, it has a much higher capacity than a jaw crusher of the same gape, and is usually favoured in plants handling very large throughputs. Large gyratory crushers often dispense with expensive feeding mechanisms and are often fed direct from trucks. They can be operated satisfactorily with the head buried in feed. Choked crushing is encouraged to some extent so that the rock-to-rock crushing produced in the primaries reduces the rock-to-steel crushing required in the secondary crushing stage, thus reducing steel consumption. Operating crushers under choke feeding conditions gives more even mantle wear and longer life. Gyratory crushers are mostly used in surface crushing plants.
Definition of Gyratory Crusher:
A gyratory crusher is similar in basic concept to a jaw crusher, consisting of a concave surface and a conical head; both surfaces are typically lined with manganese steel surfaces. The inner cone has a slight circular movement, but does not rotate; the movement is generated by an eccentric arrangement. As with the jaw crusher, material travels downward between the two surfaces being progressively crushed until it is small enough to fall out through the gap between the two surfaces.
Working principle of Gyratory Crusher :
The main shaft of the crusher is radially guided in the rolling contact bushing in the upper main shaft bearing and in the inner eccentric bushing in the lower eccentric bearing. The thrust bearing assembly arranged on the piston of the hydraulic cylinder ensures the axial support of the main shaft.
The rotation of the drive motor is transmitted via the transmission gear to the eccentric bushing in the eccentric bearing . This rotating eccentric bushing is responsible for generating the wobbling motion of the main shaft -this wobbling motion is characteristic of cone crushers.
Consequently, the crushing gap between the stationary concaves in the crusher housing and the wobbling crushing cone changes continuously.
The feed material that enters the crushing chamber from the top is continuously crushed between the crushing tools as it falls by gravitation until it exits the crushing chamber at the bottom .
The crushing gap is adjusted by hydraulically lifting or lowering the main shaft.
This hydraulic main shaft adjustment is particularly used with abrasive feed material and frequent corrections of gap setting.
It also serves as overload protection when uncrushable foreign matter finds its way into the crushing chamber.
Easy restart under load in an emergency due to hydraulic main shaft lifting and lowering.
Main shaft"jumping"under adverse crushing conditions is avoided by a pressurized hydraulic system ensuring permanent contact of the individual thrust bearing discs.
The use of a bevel gear set with cyclo-palloid toothing allows the installation of drive motors with higher ratings, if required.
