Abstract
A method of grinding metallic ingots into small chips or powder, which comprises the steps of providing a cutting element including a plurality of teeth, providing a plurality of ingots, each comprising a main body having a lower surface, a front end and a rear end, the rear end having an outwardly extending projection and the front end having a corresponding recess at least partially defined by a lower surface, the lower defining surface of the recess having an angle .alpha. associated therewith where 0.degree.<.alpha..ltoreq.90.degree.; arranging the ingots in end-to-end relation with the projection of each ingot in the corresponding recess of the next; and disposing the lower surfaces of the ingots on a guideway and feeding the ingots, front ends first, along the guideway into the cutting element to effect grinding without waste or damage to any of the grinding apparatus. An ingot configuration for practicing the method is also disclosed.
