From Allis-Chalmers' Superior Primary and Secondary Crushers. ° Actual required depends on stone hardness, reduction ratio, and so on. If a 60-in. gyratory crusher is to process material from a quarry where a shovel loads the raw material, the shovel would probably have to have a dipper capacity of at least 5 cu yd to be compatible.
A jaw crusher operates by the movement of a movable jaw in relation to a fixed one to crush large rocks into smaller pieces. It does this by using a spinning shaft that makes the movable jaw move back and forth. When the movable jaw goes towards the fixed jaw, it squishes the stuff in between and breaks it into smaller bits. ...

A fixed jaw, mounted in a V-shaped alignment, is the stationary breaking surface, while a movable, "swing" jaw exerts force on the feed material by pushing it against the stationary plate. The space at the bottom of the "V"-aligned jaw plates is the output gap that dictates the size of the crushed product from the jaw crusher.
