Abstract
A test stand has been fabricated to evaluate the new constant depth linear cutting (cdlc) concept of the U.S. Bureau of Mines. Tests have been done using an eccentrically mounted triangular-shaped drum, the linear cutter, and a standard rotary drum, for direct comparisons. The initial tests have confirmed the validity of the new cdlc concept. Dust generation, without any secondary dust suppression, has been reduced by more than 90 pct with no loss in fragmentation capability. The minus 1/8-in-mesh fines were reduced by more than 50 pct. The government holds several patents that are available for licensing to any firm wishing to pursue further development of this concept.
