A method of making a wearable surface for a device configured for material comminution includes positioning inserts adjacent to a first metal structure positioning a second metal structure adjacent to the inserts and the first metal structure such that there is a gap between the second metal structure and the first metal structure, and positioning at least one explosive adjacent to the second metal structure. The one or more explosives are ignited adjacent to the second metal structure to cause a portion of the first metal structure to deform to attach the inserts to the first metal structure. The wearable surface may be, for example, a semi-autogenous layer of a roller or may be a wearable surface of a crushing body of a crushing device configured to impact, crush, or grind material such as rock, minerals, ore or agglomerated material. Devices that include such a wearable surface are also disclosed.

1. A method of making a wearable surface for a device configured for material comminution comprising: positioning inserts adjacent to a first metal structure, the inserts being harder than the first metal structure;positioning a second metal structure adjacent to the inserts and the first metal structure such that there is a gap between the second metal structure and the first metal structure, the second metal structure having a first side facing toward the gap and a second side opposite the first side;positioning at least one explosive adjacent to the second side of the second metal structure; andigniting the at least one explosive to deform a portion of the first metal structure to attach the inserts to the first metal structure to form the wearable surface. 2. The method of claim 1 wherein the inserts are first inserts and wherein the method is further comprised of the steps of: positioning second inserts adjacent to a third metal structure, the second inserts being harder than the third metal structure;positioning the third metal structure and the second inserts adjacent to the first metal structure such that there is a second gap between the first metal structure and the third metal structure; andwherein the igniting of the at least one explosive also deforms a portion of the third metal structure to attach the second inserts to the third metal structure and also forms a metallurgical bond between a portion of the third metal structure and a portion of the first metal structure to form the wearable surface. 3. The method of claim 1 further comprising moving the second metal structure away from the wearable surface; and wherein the first metal structure is a plate, a tube, or a generally cylindrical structure and the second metal structure is a plate, a tube, or a generally cylindrical structure and wherein the second metal structure is moved away from the wearable surface by at least one of cutting and hitting the second metal structure to move the second metal structure away from the wearable surface. 4. The method of claim 1 further comprising at least one of cutting the wearable surface to a desired shape, bending the wearable surface into a desired shape, flattening the wearable surface into a desired shape, and testing the wearable surface, the at least one of cutting, bending, flattening and testing configured to permit the wearable surface to be attached to a grinding component of the device. 5. The method of claim 4 wherein the device configured for material comminution is a mill, a crusher, or a grinding mechanism and wherein the wearable surface is configured for attaching to the grinding component such that the wearable surface is able to impact material to crush the material. 6. The method of claim 4 wherein the wearable surface is a first wearable surface and the grinding component has a second wearable surface and wherein the first wearable surface is configured to permit the first wearable surface to be attached to a grinding component of a crushing device so that the first wearable surface is able to replace at least a portion of the second wearable surface of the grinding component while the device is positioned in a crushing circuit. 7. The method of claim 6 wherein the replacing of the second wearable surface of the grinding component occurs by retrofitting the grinding component with the first wearable surface. 8. The method of claim 1 wherein the inserts are comprised of a first set of inserts and a second set of inserts, the inserts of the first set of inserts being larger than the inserts of the second set of inserts, the inserts being positioned such that the first set of inserts are arranged in an alignment positioned adjacent to an alignment of the second set of inserts. 9. The method of claim 1 wherein the inserts are comprised of a first set of inserts, a second set of inserts, a third set of inserts and a fourth set of inserts, the first set of inserts being recessed at least 0.5 inches into the first metal structure, the second set of inserts being recessed at least 0.5 inches into the first metal structure, the third set of inserts being recessed at least 0.375 inches into the first metal structure, the fourth set of inserts being recessed at least 0.375 inches into the first metal structure, the inserts being recessed into the first metal structure prior to the explosion welding. 10. The method of claim 1 wherein the inserts are embedded in the first metal structure and are bonded to the first metal structure during the positioning of the inserts; and wherein a portion of the first metal structure covers the inserts after the igniting of the at least one explosive occurs; andwherein the wearable surface is configured to experience wear such that the wearable surface forms a semi-autogenous layer of the first metal structure after experiencing wear during comminution of material operations for a period of time. 11. The method of claim 1 wherein the first metal structure has a diameter and the second metal structure has a diameter, the diameter of the second metal structure being greater than the diameter of the first metal structure. 12. The method of claim 1 wherein the device is a roller mill, a cone crusher, or a mill and wherein the inserts are at least partially covered by a portion of the first metal structure after the igniting of the at least one explosive to deform the portion of the first metal occurs. 13. The method of claim 1 wherein the inserts are comprised of at least one of conical insert members, tapered insert members, spherical insert members, and cylindrical insert members. 14. The method of claim 1 wherein the material is agglomerated material, rock, stone, minerals, or ore and wherein the inserts are fully covered by a portion of the first metal structure after the igniting of the at least one explosive to deform the portion of the first metal structure occurs. 15. The method of claim 1 wherein the inserts are comprised of at least a first set of inserts and a second set of inserts, the first set of inserts being smaller than the second set of inserts, the second set of inserts being positioned within the first metal structure at a different depth than the first set of inserts. 16. The method of claim 1 wherein the at least one explosive is one of ammonium nitrate, dynamite, guanidine, amatol, cyclonite, plastic explosives, and explosive powder.
