Abstract

There is provided a method of forming a hydrocyclone body including assembling sintered alumina blocks (27) against a form (37), holding the blocks (27) in place with tape (40), locating a hydrocyclone housing over the blocks (27), filling a space between them with settable epoxy/ceramic composite to secure the blocks (27) to the casing, and removing the form (37), resulting in a substantially continuous, wear resistant surface.

First claim

The invention claimed is:

1. A method of forming a wear indicating minerals processing cyclone body including the steps of:
providing a substantially continuous wear resistant liner;
locating one or more monitoring elements on an outer surface of the liner;
locating a casing or housing over the wear resistant liner with a space therebetween;
providing a lead out from each monitoring element to an interface external of the casing or housing;
filling the space completely with a settable adhesive material; and
allowing the settable adhesive material to set.

2. The method according to claim 1 , wherein the monitoring elements include one or more transducers connected to an interface external of the body member.

3. The method according to claim 1 , wherein the lead-out from each monitoring element comprises an insulated wire passing through apertures through a side wall portion of the casing.

4. The method according to claim 1 , wherein the interface is selected from electrical terminals, slip rings and RFID devices adapted to be connected to the monitoring element.

5. The method according to claim 1 , wherein the monitoring elements comprise one or more conductors each forming a continuity testing circuit element.

6. The method according to claim 5 , wherein the conductor or conductors are spirally wound about the outer surface.

7. The method according to claim 5 , wherein the conductor or conductors are arranged in a pattern selected from generally zigzag, sinusoidal or circumferentially spiral pattern.

8. The method according to claim 1 , wherein the wear resistant minerals processing cyclone body formed thereby is selected from a cyclone separator body assembly and a cyclone separator lower cone and spigot assembly.

9. The method according to claim 8 , wherein the wear resistant liner is formed of wear resistant elements.

10. The method according to claim 9 , wherein the wear resistant elements comprise isostatically pressed sintered alumina.

11. The method according to claim 9 , wherein the wear resistant elements comprise specifically shaped elements adapted to form in assembly a frusto-conical wear surface.

12. The method according to claim 8 , wherein the monitoring elements comprise one or more conductors each forming a continuity tester each arranged in a zigzag or sinusoidal pattern having spacing of the apices of the conductor at a frusto-conical base portion of the cyclone body being larger than the spacing toward an upper truncation portion of the cyclone body.

13. The method according to claim 12 , wherein there are two or more axially interleaved zigzag, sinusoidal or circumferentially spiral conductors.

14. A method of forming a wear indicating cyclone separator component including the steps of:
providing a substantially truncated-conical wear resistant cyclone component liner;
locating one or more wire conductors on an outer surface of the liner;
locating a cyclone separator casing over the cyclone liner, an inner surface of the casing and cyclone component liner defining a space therebetween;
providing a plurality of lead-outs from each conductor to external of the cyclone separator casing;
filling the space completely with a settable adhesive material to secure the cyclone liner relative to the cyclone separator casing; and
allowing the settable adhesive material to set.

15. A wear resistant mineral processing cyclone body including: a cyclone separator having a wear resistant liner and a casing, a wherein the wear resistant liner has a substantially smooth inner surface formed of a plurality of substantially abutting wear resistant elements with one or more wire conductors located on an outer surface of the wear resistant liner, and a wherein the casing has a plurality of lead-outs from each wire conductor and wherein the casing is located over and secured to the cyclone liner by a settable adhesive material completely filling a space between the casing and the wear resistant elements in assembly.

16. A wear indicating cyclone separator body including:
a substantially truncated-conical wear resistant cyclone liner formed of a plurality of wear resistant elements;
one or more wire conductors located on an outer surface of the liner; and
a cyclone separator casing having a plurality of lead-outs from each conductor and located over and secured to the cyclone liner by a settable adhesive material completely filling a space therebetween.
