Abstract

In one aspect of the invention a degradation drum comprises a generally cylindrical body comprising inner and outer diameters. At least one degradation assembly is disposed on the outer diameter and it comprises a holder and a pick shank secured within a bore of the holder. At least one lubricant reservoir is disposed within the inner diameter and is in fluid communication with the bore of the holder through a fluid pathway. In some embodiments, the lubricant reservoir maintains a fluid pressure on the pick shank.

Claims (25)

1. A method for providing a cost effective degradation drum, comprising:

providing by a first party to a second party a generally cylindrical degradation drum comprising inner and outer diameters and a plurality of degradation assemblies disposed on the outer diameter, the plurality of degradation assemblies each comprising a pick body intermediate an impact tip comprising diamond and a pick shank, the pick shank being disposed within a bore of a holder, wherein the bore of the holder comprises a lubricant orginating from a resevior in the inner diameter of the drum, the lubricant being substantially retained in the bore by a distal seal assembly disposed within the bore and being intermediate the shank and a bore wall; and

charging the second party by the first party for use of the drum.

2. The method of claim 1 , wherein the second party is charged for the amount of time they possess the drum.

3. The method of claim 1 , wherein the second party is charged for the volume or area of material they mill with the drum.

4. The method of claim 1 , wherein the second party is charged for the distance of material that they mill with the drum.

5. The method of claim 1 , wherein the second party is charged for the weight of the material that they mill with the drum.

6. The method of claim 1 , wherein the second party is charged for the amount of wear they induce on the drum.

7. The method of claim 1 , wherein the step of providing a drum further comprises retrieving a used drum from the second party.

8. The method of claim 1 , wherein the drum is used as part of a pavement milling machine.

9. The method of claim 1 , wherein the drum is used as part of a mining machine.

10. The method of claim 1 , wherein the first party or a third party is responsible for maintenance of the drum.

11. The method of claim 1 , wherein the second party is responsible for maintenance of the drum.

12. The method of claim 1 , wherein at least one of the plurality of degradation assemblies comprises a lubricated pick shank.

13. The method of claim 1 , wherein at least one of the plurality of degradation assemblies comprises a bushing disposed intermediate the holder and the shank.

14. The method of claim 1 , wherein each of the plurality of degradation assemblies is individually replaceable.

15. The method of claim 1 , wherein the method further comprises a step of filling a lubricant reservoir.

16. The method of claim 1 , wherein the method further comprises a step of maintaining the drum by replacing worn picks and/or degradation assemblies.

17. The method of claim 1 , wherein the method further comprises a step of reusing the impact tips in another pick body.

18. A method for providing a cost effective degradation drum, comprising:

providing by a first party to a second party a generally cylindrical degradation drum comprising inner and outer diameters and a plurality of degradation assemblies disposed on the outer diameter, the plurality of degradation assemblies each comprising a pick body intermediate an impact tip comprising diamond and a pick shank, the pick shank being disposed within a bore of a holder wherein the bore of the holder comprises a lubricant orginating from a resevior in the inner diameter of the drum, the lubricant being substantially retained in the bore by a distal seal assembly disposed within the bore and being intermediate the shank and a bore wall; and

renting the drum to the second party by the first party according to a rental agreement.

19. A method for providing a cost effective degradation drum, comprising:

providing by a first party to a second party a generally cylindrical degradation drum comprising inner and outer diameters and a plurality of lubricated degradation assemblies disposed on the outer diameter, the plurality of lubricated degradation assemblies each comprising a pick body intermediate an impact tip comprising diamond and a pick shank, the pick shank being disposed within a lubricated bore of a holder, wherein the bore of the holder comprises a lubricant orginating from a resevior in the inner diameter of the drum, the lubricant being substantially retained in the bore by a distal seal assembly disposed within the bore and being intermediate the shank and a bore wall; and

charging the second party by the first party according to a rental agreement.
