Shell liner assembly

A removeable liner assembly for the shell of an ore grinding machine, the assembly including a plurality of liner segments each of which comprises:

• a. a longitudinal segment body formed from a first material and defining a mounting surface and a grinding surface, the grinding surface being irregular in shape and defining an elevated ridge which extends longitudinally of the body;
• b. means for connecting the segment body to the shell of the ore grinding machine;
• c. an opening formed entirely through the segment body and extending longitudinally within the elevated ridge, the opening defined by a wall surface that converges from the mounting surface to the grinding surface;
• d. and insert means formed from a second material and conforming generally to the shape and size of the opening, the insert means being disposed in the opening in wedging relation for retaining engagement thereby.

A removeable liner assembly for the shell of an ore grinding machine, the assembly including a plurality of liner segments each of which comprises:

• a. a segment body of predetermined size and configuration, the segment body being formed from a first material and defining a mounting surface and a grinding surface;
• b. means for connecting the segment body to the shell of the ore grinding machine;
• c. an opening formed entirely through the segment body and defined by a wall surface that converges from the mounting surface to the grinding surface;
• d. and insert means formed from a second material and conforming generally to the shape and size of the opening, the insert means comprising a plurality of separate insert members each of which is constructed to cooperate in wedging relation with at least one other insert member and the wall surface of the opening for retaining engagement thereby.
