Composition of cone crusher

(1) Crusher main frame assembly: the crusher main frame is composed of an upper frame body and a lower frame body, which are connected by hydraulic cylinders, with wear-resistant lining plates and protective covers inside: the upper frame body is a weldment, its upper mouth is welded with wear-resistant copper plates, and the lower frame body is an integral steel casting.

(2) Main shaft assembly: the main shaft and the center wheel of the lower frame body of the main frame are assembled with a small interference fit on the conical surface, and the main shaft is provided with axial and radial lubricating oil holes.

(3) Eccentric shaft sleeve assembly: the eccentric shaft sleeve is internally installed with a high lead bronze bushing fixed by screws; The lower part is installed with large bevel gear and thrust bearing through bolts, of which the upper thrust bearing is forged steel and the lower thrust bearing is high lead bronze; In addition, the eccentric shaft sleeve is also equipped with a counterweight assembly fixed by bolts, which is filled with lead and installed with a wear-resistant protective lining plate.

(4) Moving cone assembly: the upper part of the moving cone is bolted and fixed with a feeding plate assembly, and the lower part is installed with a spherical bearing bush, which can be matched with the spherical steel bush installed in the sleeve; A moving cone liner made of high manganese steel is installed outside the moving cone, and the gap between the moving cone and its liner is filled with epoxy resin; Upper and lower high lead bronze bushings are installed inside the moving cone.

(5) Fixed cone assembly: the upper part of the fixed cone is installed with a feeding hopper; High manganese steel wear-resistant lining plate fixed by large-diameter bolts is installed inside, and epoxy resin is also filled between the fixed cone and its lining plate; The outside of the fixed cone is a trapezoidal thread matched with the adjusting ring.

(6) Adjusting ring: the adjusting ring is a component, which is composed of adjusting ring, clamping ring, cam follower and hydraulic motor; There are trapezoidal threads in the clamping ring, which can be connected with the fixed cone; The upper part of the adjusting ring is equipped with a main frame fixing pin and a guide rod to prevent the adjusting ring from rotating in the main frame.

(7) Lubricating device of the unit: it is composed of lubricating oil tank, motor oil pump, filtering device, cooling device and control device. For example, the cone crusher of Yantai Xinhai mining machine adopts dry oil or water sealing methods, so that dust and impurities cannot enter the body, ensuring the cleanness of the lubricating oil.

(8) Horizontal transmission shaft assembly: a high-power main drive motor drives the small bevel gear on the horizontal shaft to drive the large bevel gear and eccentric shaft sleeve through the triangular belt pulley transmission device: the box body of the horizontal shaft is an integral cast iron, which is fixed to the main frame with bolts.

(9) Hydraulic clamping frame and iron release device: the upper components of the adjusting ring are connected to the crusher main frame through the double acting hydraulic cylinder.

(10) Adjusting mechanism assembly: use the hydraulic motor to drive the pinion, and the pinion drives the big gear ring on the adjusting cap, so as to drive the fixed cone to rotate, so as to achieve the purpose of adjusting the gap between the fixed cone liner plate and the moving cone liner plate.

(11) Hydraulic control station: the control station includes oil tank with oil meter, motor oil pump, filtering device, energy storage device, control device, pressure switch, safety protection device, etc; Terminal box and button control cabinet are also installed beside the crusher.

Matters needing attention

1. The feeding particle size ratio is appropriate.

2. Automatic control device.

3. The crusher discharge goes through.

4. Select the crushing chamber correctly for the crushed materials.

5. The feeding is evenly distributed within 360 ° of the crushing chamber.

6. The specification of the conveyor belt is compatible with the maximum output capacity of the crusher.

7. Proper selection of sieve specifications for pre screening and closed-circuit screening.
