The jaw crusher (Figure 4.1) In a jaw crusher, feed is admitted between two jaws, a stationary jaw or anvil and a movable jaw, which reciprocates in a horizontal plane. It makes an angle of 20 - 30o with the stationary jaw. It is driven by an eccentric so that it applies great compressive force on the lumps caught between the jaws.Web

The reduction ratio is then calculated by comparing the input feed size passing 80 per cent versus the discharge size that passes 80 per cent.
