Wearable Surface For a Device Configured For Material Comminution

Abstract

A wearable surface for a device configured for material comminution wherein the wearable surface is comprised of a first metal structure attached to at least one insert via a deformation of a portion of the first metal structure by a transfer of force caused by igniting at least one explosive material, the inserts being harder than the first metal structure wherein the wear surface is sized and configured to support or retain a material to be impacted and crushed by the crushing body. 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 device configured for material comminution comprising:
 a moveable crushing body;   a first surface adjacent to the moveable crushing body, the first surface sized and configured to support or retain material to be impacted by the crushing body; and   a wearable surface attached to the crushing body, the wearable surface positioned on the crushing body such that the wearable surface impacts the material to crush the material; and   at least one of the wearable surface and the first surface comprised of a first metal structure attached to at least one insert via a deformation of a portion of the first metal structure by a transfer of force caused by igniting at least one explosive material, the inserts being harder than the first metal structure.   
     
     
         2 . The device of  claim 1  wherein the first metal structure is a roller comprised of steel and the wearable surface is configured to experience wear under comminution operations to form a semi-autogenous layer of the roller. 
     
     
         3 . The device of  claim 1  wherein the device is a crusher and wherein the first surface is a surface of a bowl and the movable crushing body is a crusher head. 
     
     
         4 . The device of  claim 3  wherein the crusher is a cone crusher. 
     
     
         5 . The device 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. 
     
     
         6 . The device of  claim 1  wherein the material is agglomerated material, rock, stone, minerals, or ore and wherein the inserts are covered by a portion of the first metal structure. 
     
     
         7 . The device of  claim 1  wherein the crushing body is a die or a roller, the first metal structure is a portion of the crushing body and the first surface is a surface of an anvil, a surface of a table, a surface of a conveyor or a surface of a second roller. 
     
     
         8 . The device of  claim 1  wherein the crushing body is a roller and the first metal structure is at least a portion of the roller. 
     
     
         9 . The device 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, first set of inserts being positioned in the first metal structure and the second set of inserts being positioned within the first metal structure at a different depth than the first set of inserts. 
     
     
         10 . The device of  claim 1  wherein the inserts are one of cemented, bonded and adhered in recesses formed in the first metal structure prior to deformation of the portion of the first metal structure. 
     
     
         11 . The device of  claim 1  wherein the device is a roller mill, a cone crusher, or a mill and wherein the inserts are covered by a portion of the first metal structure. 
     
     
         12 . A device configured for material comminution comprising:
 a moveable crushing body having a wearable surface wherein the wearable surface is comprised of a first metal structure attached to at least one insert via a deformation of a portion of the first metal structure by a transfer of force caused by igniting at least one explosive material, the inserts being harder than the first metal structure;   a first surface adjacent to the moveable crushing body, the first surface sized and configured to support or retain a material to be impacted and crushed by the wearable surface.   
     
     
         13 . A device configured for material comminution comprising:
 a moveable crushing body;   a first surface adjacent to the moveable crushing body, the first surface comprising a first metal structure attached to at least one insert via a deformation of a portion of the first metal structure by a transfer of force caused by igniting at least one explosive material, the inserts being harder than the first metal structure wherein the first surface is sized and configured to support or retain a material to be impacted and crushed by the crushing body.
