Because the space between the two jaws becomes narrower towards the discharge outlet, the material size is progressively reduced. The gap between the jaws at the discharge outlet dictates the material output size. A typical jaw crusher will have a crushing ratio of between 6:1 to 8:1 i.e. the feed material size is reduced by a factor of 6 or 8.Web
