Abstract

A magnetic fastener and wear liner combination for use with material processing equipment for processing aggregate material, where a reverse taper counter bore hole of the wear liner is made to couple and decouple from a magnetic fastener which has a urethane cap, with a urethane cap reverse taper side. The magnetic fasteners are re-useable on replacement liners as the liners need replacement. The attachment and detachment of the magnetic fasteners is made to be simple and secure.

First claim

I claim:

1. A method of extending the useful life of portions of material processing equipment, comprising the steps of:
providing a piece of material processing equipment, configured for use with aggregate material, where the piece of material processing equipment is one of a crusher, a vibrating screen, a hopper, and a chute; where a portion thereof is a ferrous metal member that is exposed to abrasion by contact with aggregate material;
displacing, from said ferrous metal member, a magnetic fastener, coupled to a first liner;
removing the first liner from the ferrous metal member; and
inserting a magnetic fastener, into a hole in a second liner and allowing said magnetic fastener to engage said ferrous metal member.

2. The method of claim 1 wherein said step of displacing, from said ferrous metal member, a magnetic fastener involves removing said magnetic fastener from said first liner before said step of removing said first liner from the ferrous metal member.

3. The method of claim 1 further comprising a step of removing a plurality of magnetic fasteners from said first liner after said first liner has been removed from said ferrous metal member.

4. The method of claim 3 wherein said step of removing a plurality of magnetic fasteners is performed by pressing an exposed magnet portion of each of said plurality of magnetic fasteners and causing said exposed magnet portion of each of said plurality of magnetic fasteners to pass into and through a reverse taper counter bore hole, through said first liner.

5. The method of claim 4 wherein said step of inserting a magnetic fastener in a hole in a second liner involves a urethane cap becoming locked behind a bore hole taper side in said reverse taper counter bore hole.

6. A system for extending the useful life of a ferrous metal member of a piece of material processing equipment comprising:
a first liner configured to cover and protect a predetermined portion of a ferrous metal member in a piece of material processing equipment, said first liner having a plurality of reverse taper counter bore holes therein;
a second liner configured to cover and protect a predetermined portion of a ferrous metal member in a piece of material processing equipment, said second liner having a plurality of reverse taper counter bore holes therein;
a plurality of magnetic fasteners each configured to be lockable inside of and removable from each of said plurality of reverse taper counter bore holes in said first liner and in said second liner; and
said plurality of magnetic fasteners being further configured to magnetically engage said ferrous metal member
while disposed in either one of said first liner and said second liner while said either one of said first liner and said second liner is disposed on said predetermined portion of said ferrous metal member.

7. The system of claim 6 wherein said first liner and said second liner are manufactured to the same specifications.

8. The system of claim 7 wherein said first liner and said second liner are interchangeable without affecting performance of said system.

9. The system of claim 8 wherein said first liner and said second liner are manufactured to different specifications.

10. A system for extending the useful life of a ferrous metal portion of a piece of material processing equipment comprising:
a first liner configured to cover and protect a first predetermined portion of a first ferrous metal member in a piece of material processing equipment, said first liner having a first plurality of holes therein;
a plurality of magnetic fasteners each configured to be lockable inside of and removable from each of said plurality of holes in said first liner;
said plurality of magnetic fasteners being further configured to magnetically engage said first ferrous metal member while disposed in said first liner while said first liner is disposed on said predetermined portion of said ferrous metal member.

11. The system of claim 10 wherein said first plurality of holes includes a first plurality of reverse taper counter bore holes.

12. The system of claim 11 further comprising: a second liner configured to cover and protect a second predetermined portion of a second ferrous metal member in a piece of material processing equipment, said second liner having a second plurality of reverse taper counter boreholes therein.

13. The system of claim 10 further comprising: a second liner configured to cover and protect a second predetermined portion of a second ferrous metal member in a piece of material processing equipment, said second liner having a second plurality of holes therein.

14. A system for extending the useful life of a ferrous metal portion of a piece of material processing equipment comprising:
a first protective member configured to cover and protect a first predetermined portion of a first ferrous metal member in a piece of material processing equipment;
a plurality of magnetic fasteners each configured to be coupled to and removable from said first protective member; and
said plurality of magnetic fasteners being further configured to magnetically engage said first ferrous metal member while coupled to said first protective member while said first protective member is disposed on said predetermined portion of said ferrous metal member.

15. The system of claim 14 wherein said first protective member is a protective liner.

16. The system of claim 14 wherein said plurality of magnetic fasteners are disposed inside said first protective member.

17. The system of claim 16 wherein each of said plurality of magnetic fasteners is lockable inside of and removable from one of a first plurality of reverse taper counter bore holes in said first protective member.

18. The system of claim 17 further comprising: a second protective member configured to cover and protect a second predetermined portion of a second ferrous metal member in a piece of material processing equipment, said second protective member having a second plurality of reverse taper counter bore holes therein.
