ELECTROHYDRAULIC CRUSHER FOR PREPARATION OF MIXTURES OF REQUIRED COMPOSITION Russian patent published in 2005 - IPC

FIELD: civil engineering.

SUBSTANCE: invention is designed for crushing and grinding stone for preparing crushed stone. Proposed multielectrode electrohydraulic crusher contains crushing chamber, grid over which working electrodes are installed, and intake device common for crushed products from all electrodes, arranged under grid. Said grid is made up of at least two separate section in longitudinal direction differing from 1.4 to 9 folds in areas of through holes. Areas of through of through sections of holes in each section are mainly equal, and ratio of lengths of cross and longitudinal axes of holes does not exceed two, distance from end of working electrode to any edge of section below is not less than 1.2 of distance from end of working electrode to grid, and working electrodes are installed with possibility of changing distance between electrodes and grid. Holes of crusher grid sections can be square or round.

EFFECT: possibility of preparation of crushed stone with preset fractional composition and minimum number of slab grains at high capacity of crusher.
