Cone Crusher principle

Crushing process is fixed between the cone and the cyclic movement of the moving cone completed.

Cone crusher, the horizontal axis of the crusher is driven by an electric motor through V-belt and pulley, the horizontal axis through large and small gear driven eccentric rotation axis cone crusher produce eccentricity do spin pendulum movement in the eccentric role so broken wall surface near the cone surface from time to time, sometimes away from the cone surface, so that the stone in the crushing cavity constantly being squeezed, broken and impact crusher. After crushing the material under the action of gravity discharged from the lower part of the crusher discharge opening. Mobile cone crusher cone on chambers supported on the upper end of the spherical bearing fixed spindle, set in the eccentric sleeve outside its lower chamber, its movement driven directly by the eccentric sleeve. When the eccentric sleeve rotates around the spindle, moving cone not only with the center line of the eccentric sleeve around the rotary motion of the machine, but also about their own axis, the movable cone is supported around its center for space sphere spin pendulum movement. Dynamic cone spindle centerline axis intersect at a fixed point, namely the spherical center, the angle of the precession angle. When the crusher operation, moving cone axis relative to the center line machine conical surface movement, its cone top spherical support center, the point is moving cone of movement remain stationary. Accordingly, moving cone of movement can be regarded as a rigid body rotation around the point, that the movement of the moving cone is composed of two rotary motion: the precession motion or motion involved (fixed cone machines around the center rotary motion) and rotation movement or relative Sports (dynamic cone around its axis rotary motion).
Cone crusher in the case of a no-load operation, moving cone rotation by spherical bearings to move the cone of friction torque and friction values ​​eccentric sleeve to move the cone of the decision, which torque, the torque dynamic cone that is so direction. Under normal circumstances, moving cone is along the direction of rotation of the eccentric sleeve rotation, rotation speed is determined by the difference between the two moments. And this type of cone crusher in spherical bearings and moving cone between the bush next to control the rotation of the moving cone. In the case of a load operation, the stone of the dynamic cone cone friction torque far exceeds the friction torque of the moving cone eccentric sleeve produced.
