Structure and operation principles of cone crusher. 1) the cone crusher is made up of a frame ,transmission device , hollow eccentric shaft , bowl-shaped bearing , crushing cone , springs , and hydraulic pressure station for adjusting the discharge opening . 2) while in operation , the eccentric shaft shell is rotated by a motor through a horizontal axle. And a pair of bevel gear . Under the eccentric shaft shell drive , the axle of crushing cone seings . When it swings to the extent that the surface of the crushing wall is close to the roll mortar wall , the rocks and ores are pressed and crushed . 3) cone crusher is more advanced and efficient than than the jaw crusher . This is because the cone breaker crushes materials using the working surface between the moveable by spherical bearing , moveable cone is fixed on an erect hanging shaft . The erect shaft is set in the eccentric sleeve . The rotation of the eccentric shaft sleeve causes the movable cone and erect shaft to rotate accordingly . Since the lower part of vertical shaft is installed in the eccentric sleeve , the rotation of the eccentric sleeve will create a conical . Rocks are crushed , when the moveable cone is close to the fixed one , and are discharged when they part . 4) the wheel of conveyor belt is driven by a m
