Jaw crusher • Feed is admitted between two jaws, which are open at the top like V • One of the jaws is fixed and vertical, while the other is the swinging jaw • This jaw reciprocates in a horizontal plane and makes the angle of 2030° with the fixed jaw • Movable jaw is operated by an eccentric unit so as to impart great compressive forceHigh production and reduction C Series jaw crushers are well known for the aggressive motion of the pitman and long stroke in the bottom of the cavity The stroke is amplified from the top to the bottom, which means that the stroke is always longest in the bottom of the cavity This boosts the capacity as well as the reduction ratio, resulting in highminevik Crushing and screening solutions AggNetA general rule of thumb for applying Cone Crushers is the reduction ratio A crusher with coarse style liners would typically have a 6:1 reduction ratio Thus, with a 3⁄4” closed side setting, the maximum feed would be 6 x 3⁄4 or 45 inches Reduction ratios of 8:1 may be possible in certain coarse crushing applications Fine liner configurations typically have reduction ratiosCone Crushers McLanahan
