Using Generators with Operating Voltage of 50 kV for Electric Discharge Crushing of Quartz Raw

The results of using two generators with an operating voltage of about 50 kV for high voltage electric pulse crushing of quartz raw are presented. A comparison with previously obtained results of quartz raw crushing on a generator with an operating voltage of 250 kV is performed. Reducing the operating voltage of the generator allows improving its operating qualities and simplifying the generator design due to the exclusion of a step-up pulse transformer from the circuit. It is shown that while maintaining the energy level in the high-voltage storage and reducing the operating voltage from 250 to 50 kV, the crushing efficiency remains at the same level. An increase in the stored energy while other parameters constant does not lead to an increase in the crushing efficiency, since energy consumption and the proportion of overgrinding fraction increase.
