14 Tips for optimum use of jaw crushers: • The feed size should be 70 to 80% of the minimum opening size at top. Do not allow bigger pieces going to the crusher mouth. • Material fed should not be of same size. Mixed feed of all sizes of material gives best results. • For best results ratio of gap to jaw setting should be 5:1 to 7:1.
