In a gyratory crusher, a main shaft having a tapered mantle supporting portion extending through a correspondingly tapered bore in the crusher mantle to support the mantle on the shaft, and a bearing sleeve fitted about the end of the shaft releasably securing the crusher mantle to the tapered portion of the shaft.
The gyratory crusher is widely used in primary crushing of metal ore such as iron ore and copper ore due to its high productivity and large feed inlet [[1], [2], [3]].In recent years, with the growth of the world's population, the development of urbanization and the improvement of living standards, the demand for the ore continues to increase, therefore, the requirements of …
The main features of a Gyratory Crusher include a tall crushing chamber lined with replaceable manganese wear plates, a main shaft with head and mantle, and a spider to anchor the top of the main shaft bearing. ... For a smaller product size, the main shaft can be raised to create a smaller space between the mantle and the liners. To create a ...
For gyratory crusher, the outer circle represents the stationary bowl covered by the concave and the inner circle represents the main shaft covered by the mantle. The main shaft rests in the eccentric bushing at the base of the crusher. As the eccentric rotates, the base of the main shaft moves in a circular path around the crusher centerline.

For gyratory crusher, the outer circle represents the stationary bowl covered by the concave and the inner circle represents the main shaft covered by the mantle. The main shaft …
CITIC HIC engineers employ EDEM software to simulate a variety of different conditions, evaluate the crusher parameters, and perform finite element analysis of dynamic load, fatigue failure, lubrication, fluid flow and kinematics to design …
After finding the main reason for the fracture of the gyratory crusher main shaft, we study how to reduce the probability of the main shaft breaking. Skip to content. 0086 [email protected] Facebook …
Gyratory crushers are generally more robust than cone crushers and are well equipped to handle larger feed sizes. Gyratory crushers can be divided into two categories: cone and impact gyratory crushers. ... A steady rest, called a spider, supports the upper part of the machine. The main shaft passes through the eccentric journal at its lower ...
CG820i crusher offer excellent reliability and safer & faster maintenance – up to 30% faster than competing crushers. A robustly designed one-piece main shaft and reinforced shells are made for tough use. The one-piece spherical spider bearing offers 5 times longer wear life than competing spider bushing design.
Gyratory Main Shaft Mantle Removal ... SHARE THS POST ON; The Previous Post ; Our HP 800 Mainframe had a loose shaft and we re-fit the shaft back to OEM specs with a 2-week-turnaround to get a 3.5-million-ton-plant back up and running. ... We believe in Safety, Integrity, Commitment, Respect, and Excellence. When Big Crushers Need Big ...
A gyratory crusher main shaft sleeve for friction fitting over an uppermost end of a crusher main shaft. The sleeve comprises an elongate axial wall for positioning in contact with an outward facing surface of the main shaft. The axial wall comprises a thickness that decreases in a direction from a second upper end to a first lower end wherein ...
Gyratory crushers have an oscillating shaft. The material is reduced in a crushing cavity, between an external fixed element (bowl liner) and an internal moving element (mantle) mounted on the oscillating shaft assembly. ... An eccentric shaft rotated by a gear and pinion produces the oscillating movement of the main shaft. The eccentricity ...
The main shaft position control system allows you to easily adjust the main shaft position to compensate for liner wear and control the product size. Design benefits of gyratory crushers. A gyratory crusher consists of a solid main shaft housed within a hollow body with vertically sloping sides. When the crushing surfaces come into contact with ...
Shortly after the start-up of the loaded gyratory crusher, a severe failure issue occurred in the eccentric bushing of the crusher. Based on the analysis of working conditions and force, the failure mechanism of the eccentric bushing is studied in detail by combining macroscopic analysis, finite element analysis, scanning electron microscopy (SEM) and …
CG810i crusher offer excellent reliability and safer & faster maintenance – up to 30% faster than competing crushers. A robustly designed one-piece main shaft and reinforced shells are made for tough use. The one-piece spherical …
The most commonly-used type is a supported-shaft gyratory crusher; the main shaft is suspended from an overhead spider. The angle of the mantle is steeper than that used in a cone crusher and this causes gyratory crushers to have a smaller throw. This affects the flow of material and improves the particle shape as material is struck more ...
NT Gyratory Crusher The NT Gyratory Crusher expands on the success of Fuller's TC line, keeping all of the good stuff – the Heavy Cast-Steel Shell Sections, Forged Main Shaft and Countershaft, Robust Gearing, Generous Lubrication, Long-Life Bronze Components – and adding in more maintenance-friendly features for smoother, safer shutdowns.
The main shaft is supported by the spider at the top and by the main shaft position system (a hydraulic system of vertical adjustment) and eccentric bushing at the bottom.
Regarding possible failures, there is jaw wear (which is usually more severe in the single shaft crusher) and choking. This problem occurs when the output flow does not match the input volume, so there is a critical flow value. Gyratory Crusher. The gyratory crusher can be used in both primary and secondary crushing.
The gyratory crushers are equipped with a hydraulic setting adjustment system, which makes it possible to regulate the gradation of the crushed material. ... Another principle is that of setting the adjustment by lifting or lowering the main shaft. The advantage of this is that the adjustment can be done continuously under load.
The other most noticeable change is the crushing action of the mantle. In the Gyratory all the movement is in the bottom of the crusher mantle. This is due to the angle that the main shaft is on. The greater angle of the cone crusher puts the pivot point below the distributor plate. While the pivot point for the gyratory crusher is at the ...
