Cone head wiper replacement method and apparatus
Embodiments provide a method for removably mounting at least one wiper ring to the underside of a cone head of a cone crusher. The method includes the following steps in the order recited: inducing a temperature difference between the cone head and the at least one wiper ring; mounting the at least one wiper ring to an underside of the cone head while maintaining the temperature difference; and holding the at least one wiper ring against the underside of the cone head while the temperature difference dissipates. The temperature difference may be induced by either cooling the at least one wiper ring or by heating the cone head, or both.
1. A method for removably mounting at least one wiper ring to the underside of a cone head of a cone crusher, comprising the following steps in the order recited:
inducing a temperature difference between the cone head and the at least one wiper ring;
mounting the at least one wiper ring to an underside of the cone head while maintaining the temperature difference; and
holding the at least one wiper ring against the underside of the cone head while the temperature difference dissipates.
2. A method for removably mounting at least one wiper ring to the underside of a cone head of a cone crusher, comprising the following steps in the order recited:
cooling the at least one wiper ring;
mounting the at least one wiper ring to an underside of the cone head while the at least one wiper ring is cool; and
holding the at least one wiper ring against the underside of the cone head while the wiper ring warms to room temperature.
3. The method of claim 2 , further comprising the initial step of selecting a cone head having at least one peripheral formation in the underside thereof that complements a configuration in an underside of the at least one wiper ring, and wherein the step of mounting the at least one wiper ring to the underside of the cone head comprises mounting the at least one wiper ring to the peripheral formation.
4. The method of claim 3 , further comprising removing the at least one wiper ring by cutting the at least one wiper ring into at least two pieces and then prying the pieces from the cone head.
5. A method for removably mounting at least one wiper ring to the underside of a cone head of a cone crusher comprising the following steps in the order recited:
heating the cone head;
mounting the at least one wiper ring to the underside of the cone head, the wiper ring not having been heated; and
holding the at least one wiper ring against the underside of the cone head while the cone head cools.
6. The method of claim 5 further comprising the initial step of selecting a cone head having at least one peripheral formation in the underside thereof, and wherein the step of mounting the at least one wiper ring to an underside of the cone head comprises mounting the at least one wiper ring to the peripheral formation.
7. The method of claim 6 wherein the step of selecting a cone head having at least one peripheral formation comprises selecting a cone head having at least one peripheral formation that extends around the entire circumference of the underside of the cone head.
8. The method of claim 5 , further comprising the step of cutting the at least one wiper ring into at least two pieces and then prying the pieces from the cone head.
