2. GYRATORY CRUSHERS

2017-4-19  The parameters used in the basic design of a gyratory crusher are nip angle, feed rate, feed opening, closed-side setting, work index, and horsepower. The combination of the nip angle, feed opening, and closed-side setting determine the length of the crushing chamber and indirectly the length of the main shaft.
