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 resistant minerals processing body including the steps of:
assembling wear resistant elements to form a substantially continuous wear resistant surface against an outer surface of a form;
locating a casing over the wear resistant elements with a space therebetween;
filling the space with a settable adhesive material;
allowing the settable adhesive material to set in order to secure the wear resistant elements relative to the casing; and
removing the form wherein the wear resistant minerals processing body is selected from a cyclone separator body assembly and a cyclone separator lower cone and spigot assembly.

2. The method according to claim 1 , wherein the wear resistant elements comprise isostatically pressed sintered ceramic material.

3. The method according to claim 2 , wherein the ceramic material is alumina.

4. The method according to claim 1 , wherein the wear resistant elements comprise specifically shaped elements adapted to form, in close abutment, a frusto-conical surface comprising said substantially continuous wear resistant surface.

5. The method according to claim 1 , wherein the form comprises a substantially truncated-conical outer surface against which the wear resistant elements are assembled.

6. The method according to claim 1 , wherein the casing is of steel and provided with one or more end flanges.

7. The method according to claim 1 , wherein the settable adhesive material is selected from a resilient material and a thermoset resin material.

8. The method according to claim 7 , wherein the settable adhesive material is selected from mineral-filled epoxy grouting materials.

9. The method according to claim 8 , wherein the mineral-filled epoxy grouting materials comprise ceramic beads.

10. The method according to claim 1 , including providing monitoring means in the space between the wear resistant elements and the casing.

11. The method according to claim 10 , wherein the monitoring means includes one or more transducers connected to an interface external of the casing.

12. The method according to claim 10 , wherein the monitoring means comprises one or more conductors each forming a continuity testing circuit element having an interface external of the casing.
