SYSTEM AND METHODS FOR PROCESSING SOLID MATERIALS USING SHOCKWAVES PRODUCED IN SUPERSONIC GASEOUS VORTEX Russian patent published in 2019 - IPC B02C19/06 

FIELD: crushing or grinding of various materials.

SUBSTANCE: group of inventions relates to systems and methods for processing solid materials by means of shockwaves generated in a supersonic gas vortex. Said system comprises a solid material feeder, a reactor with a chamber, a solid material inlet, a gas inlet from a gas source, and a gas outlet and a storage. Said reactor is made with the possibility of carrying out chemical reactions and grinding the solid feed material by means of shockwaves in the chamber. Said output includes a Venturi tube to increase the pressure in the chamber and perform rapid cooling of the treated solid material leaving the reactor. Said storage is made with the possibility of collecting the processed material transmitted through the outlet of the reactor. Said gas inlet contains an inlet nozzle configured to accelerate the gas flow to supersonic speed and emit shockwaves from the inlet nozzle into the chamber, while the inlet nozzle is additionally configured to control the shockwaves introduced into the chamber so that they occur at different frequencies. This method of processing solid materials comprises the steps of introducing a high-speed gas flow into the reactor chamber, creating a supersonic gas vortex in it, controlling the shockwaves introduced into the chamber. Further, the solid material is fed into the chamber, where it is treated with shockwaves, and, after having been processed, it is passed through the outlet of the reactor and is then collected.

EFFECT: processing by shockwaves increases the degree of abrasion of solid materials.
