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 ...
