CONICAL INERTIAL CRUSHER Russian patent published in 1995 - IPC

FIELD: concentrating mill. SUBSTANCE: crusher has bed 1 with outer cone 2 and housing for spherical support 3 of inner cone 4 whose shaft 5 is connected with cylindrical bearing bushing 6 of unbalance 7 which encloses it. The distance between the center of gravity of unbalance 7 and center of sphere of the support of the inner cone is a function of eccentricity, unbalance, cone nutation angle, mutual position of the sphere center of the cone support over the height and edges of bearing of the unbalance bushing and length of the spindle and mass of the unbalance bushing. In addition, the distance depends on inertia moment of main members of the construction which are incorporated into the cone drive and its support. EFFECT: enhanced reliability. 3 dwg
