Abstract
Under analysis is electrohydraulic crushing of rocks under electric charge using nanosecond high-stress pulses to optimize ore pretreatment. A nanosecond high-voltage generator of pulses at a capacity to 500 MW is designed and tested. A flow-through discharge cell at a voltage to 550 kW is developed. The new method of mineral crushing is highly efficient and enables designing commercial plants for electrohydraulic rock processing.
