Jaw Crusher Working Principle – StudiousGuy
A jaw crusher mainly works on the principle of reciprocating motion exhibited by the moveable jaw of the jaw crusher. The repeated movement of the jaws results in the development of compression force that further causes the breakdown of the rock or the ore placed between the two jaws into smaller pieces.
What Is A Jaw Crusher
A comparison of jaw crushers with the same capacity reveals that double-toggle jaw crushers are more expensive than ordinary jaw crushers. For this reason, mostly single-toggle jaw crushers are used in the aggregate sector, while double-toggle jaw crushers are used mostly for crushing very hard and highly abrasive materials.

Hence, increasing the crushing efficiency with the jaw crusher reduction ratio depends on the amount of material fed into the crusher's chamber. For instance, a jaw crusher with a choke-fed chamber performs best and maximizes production capacity while producing uniformly broken particles. As such, a choke-fed chamber increases your crusher ...
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.
