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 …

The same approach was used for investigating the influence of liner wear on crushing performance for a primary gyratory crusher [71]. Fig. 6 shows an example of flow and breakage prediction in a ...

The unique design emphasises safety, easy maintenance and efficient crushing performance. Unlike other gyratory crushers, which require workers to get in underneath the crusher to perform maintenance tasks – a high-risk operation – the TS range allows service and maintenance to be carried out from above. The eccentric assembly, …

A gyratory crusher includes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when the …

The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the …
