ELECTRIC PULSED CRUSHING-SEPARATION METHOD AND DEVICE Russian patent published in 2020 - IPC B02C19/18 B02C23/00 

FIELD: technological processes.

SUBSTANCE: group of inventions relates to a method of crushing-separation of substances and a device for realizing said method, which can be used in enrichment, construction and chemical production. Method comprising feeding into vessel with liquid of large pieces of substance, which are crushed into smaller particles to form colloids under action of electrohydraulic impacts, vibration and temperature, and separation, which is carried out outside capacity by radiation illumination, wherein the stream of particles is viewed by detectors transmitting signals to a computer control system, a guiding instruction of the pneumatic system for gas firing from the stream of particles into a separate container, given by light, color or shape. Processes of crushing and separation of particles form a single process and take place simultaneously in an overlapping volume, in which part of energy stored in the capacitor is used for separation. So, the discharges of the shaping and working interval are used as radiation sources of particles, vibration for their movement, heating for intensification of glow of particles, and separation of colloids for increase of intensity of particles separation. Device comprises an electrohydroimpulsive crusher including a loading hopper with a liquid, a plug, a valve, a capacitor, a transformer, forming a discharger and a working gap, a separator comprising grids, inclined vibrating tray, screen, radiators, detectors, computer system for control and signal output for pneumatic system with ejectors, separate containers for collection of particles. Crusher and separator represent a single structure in which a discharger made as a radiator provides the possibility of detecting particles belonging to a certain chemical composition by means of detectors. At that, the conical bin is a negative electrode, and two or more anodes are made in the form of rod electrodes installed along the inner diameter of the hopper in front of the grids with cells of the specified value.

EFFECT: method and device provide higher quality of crushing and separation.
