For those with high hardness of pebbles or coal gangue, it is difficult to break the Gyratory Crusher, and it is flat flaky. The raw material and the Gyratory Crusher are not very good, because the flat flaky material will break down from the gap between the two rollers during the crushing, so that the crushing effect is reduced.
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 bottom, the characteristics of the machine are ...
gyratory crusher. Two photographic techniques were utilized to assess the feed fragmentation, considering the lithological origin of the ore as an indicator of hardness. The results indicate ore hardness is most influential in mid-range fragmentation, with a marginal effect in coarser fragmentations.
Graney More aggressive blasting strategies will have significant benefits to total circuit energy usage such as in a SAG-ball mill circuit, and do have some benefit at the primary crushing stage. While primary gyratory crushers by design are energy efficient, the design of the chamber has a large effect on the power draw, and maintaining ...

Crushing Applications Steve Lovell Introduction Large bevel gears drive the crushing machines used to process ores and minerals in the hard-rock mining and aggregates industries. Among the most common machines of this type are gyratory Fig. 1 crushers and cone crushers Fig.2. The gyratory crusher is typically the first process step after
1. Gyratory crusher Product principle. The upper end of the main shaft with the crushing cone is supported in the bush in the middle of the beam, and the lower end is placed in the eccentric hole of the shaft sleeve. When the shaft sleeve rotates, the crushing cone makes an eccentric revolving movement around the center line of the machine.
