A method of conical crushing to achieve the grinding of feed material includes narrowing the crusher setting beyond the specified minimum limit to enable the head (20) to periodically exert high levels of compressive crushing force, interspersed with low pressure relief periods for mixing of the particles (70), the cycle of crushing periods corresponding with the gyrational cycle of the head (20). The method also includes increasing the releasing force exerted upon the crusher bowl (26) to promote the grinding action of the crusher at its narrowed setting. |
