Abstract. Detail descriptions of designs are given of large gyratory crushers that are used as primary crushers to reduce the size of large run-of-mine ore pieces to However, for the purposes of this approach it has been assumed that the additional specific energy for ball milling is the same as the difference in specific energy Predicting the overall specific energy requirement of crushing,

Selecting the Right Crushing Equipment Agg-Net
Cone and gyratory crushers Cone and gyratory crushers are both gyrating-shaft machines. They have a main shaft that gyrates and provides the crushing motion. Crushing takes place between a fixed outer crusher member (the concave ring) and a moving inner crushing member (the mantle) mounted on the gyrating shaft assembly.The gyratory crusher consists of a long, conical, hard steel crushing element suspended from the top. It rotates and sweeps out in a conical path within the round, can perform as a tertiary crusher when installed in a close circuit between secondary crusher and ball mill to crush any overflow material of vibratory screening.
