ELECTROHYDRAULIC CUMULATIVE DEVICE FOR DESTRUCTION AND CRUSHING OF HARD MATERIALS Russian patent published in 2010 - IPC B02C19/00 F42B1/02 

FIELD: technological processes.

SUBSTANCE: invention is related to electropulse destruction and crushing of hard materials and may be used in ore-dressing, metallurgical, construction industry. Device comprises cylindrical body filled with water, electric insulator, and two electrodes connected to generator of high-voltage pulses. Electric insulator is installed in upper end of body with provision of sealed cavity and is arranged with openings, where two electrodes are installed as parallel, besides body is arranged with cumulative indents separated from it by means of facings filled with liquid with density that exceeds water density. Body and facings are made of plastic material. Solution of table salt is used as liquid for filling of facings.

EFFECT: improved efficiency of hard materials destruction and crushing.
