ELECTRIC-PULSE DISAGGREGATORS OF SPARK-SERIES

Electric-pulse disaggregation (EPD) is a comminution technique that liberates all mineral grains from any rock type, irrespective of its lithology or grain size distribution. Normal mechanical crushing of whole-rock samples is replaced by the effect of an explosion, which is produced by applying an electric current from a high-voltage power source. The sample sits under water in a special crushing-chamber of an original design and construction (SPARK-2, CNT, Russia). The rapid distribution of electric pulses through the sample leads to explosions, which occur preferentially along grain boundaries (zones of weakness). As a result, individual, undamaged mineral grains can be liberated and recovered in their original shape and form regardless of grain size.
