Cone Crusher Diagram: Simplified Guide
The crushed ore is then moved by conveyor to the secondary crushing stage. A cone crusher is used here. The ore goes into the cone crusher's feeding system, which usually has a hopper and a feed distributor. The feed distributor ensures an even and consistent flow of material into the crushing chamber. It easily handles the coarse materials.

Crushing in Mineral Processing
The Crusher throw is defined as the distance in the direction of compression the moving crushing surfaces/plates travel from OSS to CSS. Throw = OSS – CSS. OSS and CSS will define a crusher's performance. The throw of the crusher is the distance that moving jaw moves in going from OSS to CSS. The capacity is a function of size and OSS.

Forces in a Cone Crusher | Steel in Translation
Abstract The literature on the design of cone crushers and analysis of the corresponding crushing processes is mainly based on empirical observations. As a result, it is generally accepted that the crushing action is due solely to compressive forces. Crushers are designed on that basis. Accordingly, many cone crushers today are characterized by common …
