CONICAL INERTIAL CRUSHER WITH UPGRADED DRIVE Russian patent published in 2016 - IPC B02C2/00 

FIELD: machine building; disintegrators and devices for crushing.

SUBSTANCE: invention can be used in construction and mining and concentrating industries. Crusher comprises housing 1 mounted on foundation 9 with elastic dampers 10 and having outer cone 2 arranged inside external cone 2 and inner cone 3. Eccentric weight 6 is fixed on drive shaft of inner cone 3 by means of sliding sleeve 12. Eccentric weight 6 is installed with possibility of adjustment of center of gravity relative to rotation axis, sliding bush 12 of eccentric weight 6 is connected with transmission coupling 13, through which torque is transmitted from engine. Transmission coupling 13 is shaped as disc coupling made up of drive half-coupling, driven half-coupling and located between floating disk. Driven half-coupling is rigidly connected with sliding bush 12 of eccentric weight 6, drive half-coupling is connected with with gear 22, which is rigidly connected with counter eccentric weight 11. At that, drive half-coupling, gear 22 and counter eccentric weight 11 are installed on sliding sleeve so that drive half-coupling 27, gear 22, counter eccentric weight 11 and sliding sleeve form single movable dynamic unit. Single movable dynamic unit is installed by means of support disk on fixed rotation axis 23, which rests on flange 24 rigidly secured at case 1 bottom of crusher.

EFFECT: proposed crusher enables to solve problems of dynamic balancing, reduce height and increase degree of crushing.
