The Structure And Troubles Of Gyratory Crusher

The structure and troubles of gyratory crusher

(1)The two cone shape of gyratory crusher are in steeply inclined, the movable cone is erect frustum cone ,and fixed cone is headstand frustum cone, which is mainly used to magnify the feeding end. The two cones of medium and fine cone crusher are both gentle dip erect frustum cones, and between the two cones, there is a certain length parallel crush section (parallel band), which is used to control the granularity of product, for the design of medium and fine crusher is based on the quality and capacity of crusher. (2) The movable cone of gyratory crusher hangs on the beam in the upper of the machine, while the movable cone of medium and fine crusher supports at the lower spherical bearing.

(3) Gyratory crusher adopts dry dust keeper, while medium and fine crusher uses Water seal dustproof device.

(4) Gyratory crusher uses the rise and down of movable cone to adjust the discharging end, while medium and fine crusher adjusts the discharging width by adjusting the height of fixed cone (adjusting ring).

Gyratory crusher common troubles and solutions as follows:

1. Water is mixed in lubricating oil. We solve the problem by checking if the connected part leakage of coolant clarifier. And ensure the water pressure lower than oil pressure.

2. The pressure difference of indicating pressure gauge is too large. So, we must clean the coolant clarifier when the pressure difference is over 0.04MPa.

3. Oil pressure reduction. So, we should check and replace the oil pump, heat oil with electric heater, and turn on the switch properly.

4. Oil pressure increase as well as the reflow temperature. We should stop machine to check the real reason and avoid it.

5. Distil-off temperature over 45 degree. So, we should connect to cool water and check the temperature.

6. Reflow temperature over 60 degree. There must be the problem of eccentricity axis sheath. The solution is the same as 4.

7. Filling gauge indicates the oil is full, but the temperature is 60 degree passed through lubricating parts. We should check the bearing.

In order to guarantee the cycle movement of movable cone, its bottom surface are sphere and be supported on the spherical bearing. The weight of movable cone and main shaft is bearing by spherical bearing and rack.
