INERTIAL CONE CRUSHER Russian patent published in 2008 - IPC B02C2/00 

FIELD: mining industry; other industries; production of the inertial cone crushers.

SUBSTANCE: the invention is pertaining to the field of mining industry. The inertial cone crusher contains the body with the outside cone and the spherical support for the inside cone with the shaft, on which there is the unbalanced mass vibrator, which is connected by the transmission with the power-driven electromotor. The inside cone is supplied with the amplitude limiter. The amplitude limiter is made in the form of the bearing mounted inside body, which inner race is the rubber-lined, and the mating ring of the limiter is mounted on the unbalanced mass vibrator concentrically to the axis of the cone shaft. At that the restraining radial clearance «d» between the mating ring and the rubber-lined race of the bearing is determined from the following dependence: d = S*L/1, where S - the discharging latch between the cones, L - the distance from the center of the spherical support up to the geometrical center of the mating ring; 1 - the distance from the center of the spherical support up to the lower edge of the working surface of the lining of the inside cone. The invention improves reliability and the operational service life of the inertial cone crusher.

EFFECT: the invention ensures the increased reliability and the operational service life of the inertial cone crusher.
