Claims
- 1. A method for making a screen assembly for a vibratory separator, the method comprising
gluing together with glue at least two layers of fine screening material, allowing the glue to set, preheating the glued-together at least two layers of fine screening material, placing the thus-preheated at least two layers of fine screening material in a heating apparatus, placing a coarse mesh layer on the at least two layers of screening material on the heating apparatus, placing on the coarse mesh layer a support with heat activated material thereon for adhering the support to the coarse mesh layer, and heating the coarse mesh layer, the at least two layers of fine screening material, and the support to adhere the support to the coarse mesh layer and to glue the at least two layers of fine screening material to the coarse mesh layer.
- 2. The method of claim 1 wherein the glue is moisture-curing hot melt glue.
- 3. The method of claim 1 wherein the glue glues together the coarse mesh layer and the at least two layers of fine screening material.
- 4. The method of claim 1 further comprising applying additional glue to the coarse mesh layer.
- 5. The method of claim 1 wherein the additional glue is applied in at least one line on the coarse mesh layer.
- 6. The method of claim 5 wherein the at least one line is at least two spaced-apart lines.
- 7. The method of claim 5 wherein the at least one line is applied lengthwise on the coarse mesh layer.
- 8. The method of claim 7 wherein the at least one line is applied in an amount sufficient to effect a barrier to solids migration between the coarse mesh layer and a lowermost layer of the at least two layers of fine screening material, said lowermost layer adjacent the coarse mesh layer.
- 9. The method of claim 1 wherein the at least two layers of fine screening material are glued together by applying a pattern of glue beads to at least one of said layers with a glue application apparatus.
- 10. The method of claim 1 wherein the at least two layers of fine screening material are comprised of a plurality of interwoven wires and wherein the preheating is sufficient to effect elongation of the wires of the at least two layers of fine screening material.
- 11. The method of claim 1 wherein the coarse mesh layer ranges between 15 mesh and 25 mesh.
- 12. The method of claim 1 wherein the at least two layers of fine screening material comprises a first layer and a second layer.
- 13. The method of claim 12 wherein the first layer ranges between 30 mesh and 200 mesh and the second layer ranges between 50 mesh and 300 mesh.
- 14. The method of claim 1 wherein the glued together at least two layers of fine screening material are preheated for between thirty and sixty seconds.
- 15. The method of claim 1 wherein the support is a frame.
- 16. The method of claim 1 wherein the heat activated material is epoxy adhesive.
- 17. The method of claim 16 wherein, following adhering of the coarse mesh layer to the support, cure of the epoxy adhesive is accelerated.
- 18. The method of claim 1 wherein each of the at least two layers of fine screening material are comprised of interwoven wires, the coarse mesh layer is comprised of interwoven wires, and wires of the coarse mesh layer have a diameter at least three times a diameter of wires of the at least two layers of fine screening material.
- 19. A method for separating components of a fluid, the method comprising
introducing the fluid to a vibratory separatory, the vibratory separatory comprising a screen assembly mount, vibrating apparatus for vibrating the screen assembly mount, and a screen assembly mounted to the screen assembly mount, the screen assembly made by a method as in claim 1, and vibrating the screen assembly mount thereby vibrating the screen assembly as the fluid is fed onto the screen assembly.
- 20. A screen assembly made by the method of claim 1.
- 21. A method for making a screen assembly for a vibratory separator, the method comprising
gluing together with glue at least two layers of fine screening material, allowing the glue to set, placing a coarse mesh layer on the at least two layers of screening material, preheating the glued-together at least two layers of fine screening material, and the coarse mesh layer, the coarse mesh layer having at least one line of glue material thereon, placing the thus-preheated at least two layers of fine screening material and the coarse mesh layer in a heating apparatus, placing on the coarse mesh layer a support with heat activated material thereon for adhering the support to the coarse mesh layer, and heating the coarse mesh layer, at least two layers of fine screening material, and the support to adhere the support to the coarse mesh layer and to glue the at least two layers of fine screening material to the coarse mesh layer.
- 22. Any invention disclosed herein.
