Cone Crushers

1.The Introduction to China Cone Crusher 

With the development of mining technology,China cone crusher can be divided into several types, which can conclude the spiral China cone crusher, hydro pressure China cone crusher and compound cone crusher according to the kinds; which also can be classified into PY cone crusher, Symons cone crusher, compound cone crusher, standard hydraulic pressure cone crusher, single stage cone crusher and multiple hydraulic China cone crusher according to its different types.  

China Cone crusher is one hydraulic pressure crushing machine with higher crushing ratio, higher output and higher power. This cone crusher is developed on the basis of all kinds of international cone crusher, whose structure design is obviously different with the comparison of the traditional cone crusher, which combines the main merits of all types of China cone crushers, which is used for crushing rock, mining stone, slag and refractories.

 The brief introduction to structure and main parameter of cone crusher: the cone crusher is mainly made up of rack, horizontal axis, moving cone, balance wheel, eccentric sleeve, upper crushing wall (fixed cone), under the crushing wall (dynamic cone), fluid couplings, lubrication system, hydraulic system, control system.

 Cone crusher is used in the industries of metallurgy, construction, road building, chemical and silicate industry in order to realize the crushing of material, and which also can crush all kinds of rock and mining stone with the medium hardness and above on. Cone crusher has some merits such as higher crushing ratio, higher working efficiency, low consumption, medium granularity, and some rock and mining stone which is used for medium and fine crushing. 

2. Hydraulic cone crusher working principle

The crushing process is completed between the fixed cone and moving cycle's movement. When the cone crusher is working, the horizontal axis of crushing machine is driven by motor through belt and pulley, which is driven by the eccentric sleeve rotation, and the eccentricity does the spin pendulum movement, so that the crushing wall surface sometimes is close to the fixed cone surface, sometimes away from the surface of the fixed cone crusher cone axis under the action of the eccentric sleeve, which causes the impact, friction and extrusion of material in the cabinet. The crushed material is discharging from discharging opening with the gravity of them. Cone crusher on the chamber support fixed spindle upper end of the spherical bearing on its inferior vena sets the outside of the eccentric sleeve, and its movement is driven directly by the eccentric sleeve. The dynamic cone and the axis of the spindle centerline keep stationary at a fixed point, i.e., the spherical center point, the angle of the precession angle. When the crushing machine is working, cone axis is moving on the conical surface that is the top of the cone for the spherical bearing center, the point in the process of moving cone movement always remains stationary relative to the machine centerline. So The moving cone movement can be seen as rigid body around the fixed point of rotation, that is to say, the moving cone movement is composed of two rotational motions: one is the moving cone rotating moves around the machine centerline: the other is the moving cone moves around own axis rotary motion

3. The Reliable Sealing:

The labyrinth seal device, instead of the water seal used in the past is widely applied in cone crusher, so that the dust and impurities cannot enter to the human-machine body, thereby ensuring the Run clear oil cleaning, extending the sliding bearing, the life of the thrust ball bearings, making the machine and reliable operation.

5. China Cone Crusher

The existing of gap between china cone crusher and the overseas is based on the previous spiral cone crusher belonging to Soviet Union at 1950s, and then the cone crusher is practiced so many times, which has several types such as spiral cone crusher, bottom single stage cone crusher and multi-cylinder hydraulic cone crusher, whose specification is full. But the gap between the national and international is still large.
