He outlines three simple rules behind properly sizing a jaw crusher. Rule #1: Identify maximum feed size. The size of the crusher opening directly determines the maximum feed size going into the crusher. For example, if the jaw has a 30-in. opening (gape), the maximum feed size should not exceed 80% or 24-in.
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 …
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. ...
