INSTALLATION FOR SELECTIVE DISINTEGRATION OF SOLID MATERIALS Russian patent published in 2023 - IPC B02C19/18 

FIELD: devices for selective disintegration.

SUBSTANCE: invention can be used in the preparation of mineral raw materials for processing by various methods. The plant includes a pulp preparation unit, a nanosecond high-voltage pulse generator, a magnetic compressor, inductive energy storage devices with a saturable magnetic circuit, high-voltage semiconductor current interrupters, a pulp preparation system, a pipeline, and a multi-electrode discharge cell. At the same time, to synchronize the generation of voltage pulses and the formation of multichannel completed electrical discharges in the pulp with a time spread between channels of no more than 1 ns, the nanosecond high-voltage generator has several terminal inductive storage devices connected in parallel with individual semiconductor current interrupters. Moreover, the inductive accumulators are made on a single saturable magnetic circuit of the last compression link of the magnetic compressor. The discharge cell for treating the pulp with completed electric discharges has a multi-electrode system, each of the pairs of electrodes of which is connected to its own inductive storage. Pairs of bipolar electrodes of the discharge cell are installed in a line, the distance in the line between the pairs of electrodes is equal to the distance at which the shock wave from the discharge channel of the completed electric discharge in the pulp is transformed into a sound wave.

EFFECT: increase in productivity and efficiency of the process of selective disintegration of solid materials.
