1938 to 1950 - All of the major gyratory crusher manufactures converted from spider suspended designs to hydraulically supported designs. The concaves were changed from straight faced to non-choking Bell-Head fittings and the bushings were converted from Babbitt to bronze. This period, which was severely constrained by WWII, represents the …

>Training Manual
Non-choking concaves. All of the crushers mentioned to date were outfitted with straight liner profiles. Beveled concaves – flared outward at bottom – were first tried in the fine reduction gyratory crushers as a means of improving wear distribution. The success of these first efforts gave rise to further experiments in cavity design and ...
>Performance Monitoring for a Crushing Plant
Non-choke feeding to crushers is avoidable through smart plant-wide crushing plant controls. But in order to estimate severity of that in a systematic manner is not straight-forward without constant monitoring and reporting. The crusher choke feeding report makes use out of crusher cavity level sensors by analyzing their level measurements.
>High Capacity Crusher
When the non-choking feature was being applied to existing crushers of the gyratory type, it was found that in several crushing machines, the attendant …
>EQUIPMENT AND MAINTENANCE
by increasing the crusher chamber length, nip angle can be reduced in some cases to less than 20 degrees. When combined with the improved non-choking jaw plates a more efficient crusher results. The addition of automatic lubricating systems on crushers has ensured that lubrication is properly distributed to critical areas at all times.
>Gyratory Crushing Archives
Gyratory Crusher Concaves. Concaves on the right illustrate the cross section of a typical gyratory crusher, while the left illustrates the same crushing chamber, except that, in place of the straight-face concave, the non-choking type has been substituted.

>Jaw Crusher Working Principle
The combination of favorable crushing angle, and non-choking jaw plates, used in this machine, promotes a much freer action through the choke zone than that in the Dodge crusher. Capacities compare very favorably with comparable sizes of the Blake machine with non-choking plates, and permissible discharge settings are finer.
