ABSTRACT:
An impact disintegrator for ore and rock material includes an annular grizzly for supporting an annular array of closely associated chunks of target material, which preferably are the same as the ore or rock material to be disintegrated, and a rotary slinger disposed centrally of the grizzly for forcibly slinging pieces of the ore or rock material to be disintegrated outwardly toward and against the array of chunks supported by the grizzly. The slinger is designed to also act as a blower to force air into the disintegrator. A plurality of chutes depend from beneath the grizzly for receiving disintegrated ore or rock materials resulting from the impact of the slung pieces against the array, and means may be provided for bleeding off fines from the disintegrated material received by the chutes.
