ABSTRACT:
A novel laminar assembly for use with comminution equipment, such as a liner for protecting the shell of an ore crushing mill or as a wear tip on a blow bar for use in a rock impact crusher. The laminar segment includes a plurality of laminae which are attached to each other with a pair of rods extending through a pair of axial holes positioned in the base of the laminae, thereby forming a segment of virtually any desired length. Conventional mounting bolts may extend through radial holes in the laminae between the axial holes to attach the liner segment to the comminution equipment. The utilization of small laminae enable the laminae to be formed from hardened materials such as heat treated steel or cut from a plate and then heat treated such that the microstructure throughout the laminae may be strictly controlled, thereby providing a laminae with consistent hardness and toughness throughout the laminae.
