A method and apparatus of comminuting ore-like material to produce a disproportionately large volume of flakier product which is easily and more efficiently ground in a mill, wherein the method includes the application of a stream of liquid all around the inlet of a conical crusher, increasing the speed and reducing the throw of the crusher to produce a generally flaky product, crushing the ore in the presence of the liquid and passing the ore and liquid slurry directly to a grinding mill.

A method of crushing minerals by means of a cone crusher having a specified maximum head diameter and comprising a material inlet, a conical head of corresponding maximum head diameter, an annular inner bowl liner against which an annular outer mantle on said head crushes incoming material in a gyrating cycle, said bowl liner and mantle having a circumferential gap or cavity therebetween, said crusher having specified head throw and gyrating speed characteristics, said method comprising: providing a source of crushable, particulate material; directing a flow of liquid into said gap between said bowl liner and said mantle so that said bowl liner and mantle bounding said gap are continually moistened and said liquid is mixed with said material to form a slurry in said crusher cavity; whereby crushing said slurry in said crusher creates a significant proportion of flaky shaped particles in the crushed material.
