Cone Crusher Cross-Section. The spring cone crusher design is able to pass uncrushable materials e.g. tramp metal, through the crushing cavity by using springs. The first hydraulic cone crusher was developed in 1948 and this allowed for the opening of the crushing cavity hydraulically, instead of using springs (mechanical actuation). Both the ...
Compared to the gyratory crusher, the cone crusher is characterized by its higher speed and a flat crushing chamber design which is intended to give a high capacity and reduction ratio for materials suitable to this type of processing. The aim is to retain material longer in the crushing chamber to do more work on material as it is being processed.

used to derive a cone crusher size reduction control strategy. Manipulated variables, MVs There are three possible MVs that can be used to regulate the cone crusher size reduction: 1. Closed side setting (CSS), governing the volumetric capacity of a crusher 2. Eccentric speed (ωes), governing the number and intensity of crush-ing events
Significant variations were observed in the performance of the crushers, with reduction ratios varying from 1.6 to 4.4. Nevertheless, a distinct non-normalizable breakage behavior was evident with an inflection point at around 240 µm. ...
