Cone Crushers. Originally designed and developed by (1920). Similar to gyratory except the spindle is supported at the bottom of the gyrating cone instead of being suspended. The head to depth ratio is larger than gyratory crushers. Cone angle are flatter and the slope of the mantle and concaves are parallel.Web

Primary crushers are solidly built to receive large lumps of rock directly from the mines and designed for large tonnage throughputs. Basically, gyratory crushers consist of a fixed solid conical shell or bowl (also called concaves) and a solid cone within the bowl called a breaking head (Figure 5.1).The breaking head is fixed to a central spindle, which …Web

Cone crusher theory. The functional principle of a cone crusher is to compress particles between two surfaces. Particles can be subjected to two different modes of compressive breakage; single particle breakage (SPB) and inter-particle breakage (IPB). The particle bed in the inter-particle breakage mode can either be confined or unconfined.Web
