ABSTRACT:
An ice disaggregation system comprising a multiplicity of aligned and successively longer sledging teeth outwardly extending from a rotatable drum. The drum rotation allows the successively longer teeth to sequentially cut and chip deepening grooves in various forms of particulate matter such as ice or coal engaged by the system. A second form of slugging tooth, outwardly extending from the drum, is provided in generally central alignment between paired rows of sledging teeth. The slugging tooth is positioned to subsequently engage the isolated, ridged sections of ice between successive grooves therein, and for striking said ridges with sufficient force to impart shear fracture thereto. The drum is provided with a plurality of sledging and slugging teeth in staggered groups comprising a spiral configuration along the drum. In this manner the system is particularly adapted for sequentially disaggregating engaged ice floes in a vertically descending direction for permitting the broken sections thereof to be carried freely upward by the buoyant force of the water therebeneath.
