VORTEX-ACOUSTIC DISPERSANT Russian patent published in 2005 - IPC

FIELD: production of vortex-acoustical dispersants.

SUBSTANCE: the invention is intended for high-performance fine grinding of polydispersed materials. The vortex-acoustical dispersant contains: a loading device, a connecting pipe for the finished products withdrawal, elements of distortion of the fields of the gas-suspension flow, channels of return of the material for regrinding, a system of an aspiration of the treated material, a chamber of the basic grinding and a chamber of regrinding are rigidly linked to each other through a separation unit consisting of two cone-cylindrical cowlings coaxially mounted in its body, in which there are windows. And channels of return of the material for regrinding are made in the form of the cylindrical connecting pipes located in the lower part of the cone-cylindrical cowlings is connected to the unit of the acoustical emission radiation having in its upper part a parabolic element. The upper part of the chamber of regrinding is connected to a dust-depressing device. Inside the dust-depressing device on the top cover of the chamber of regrinding there are truncated cones with rectangular apertures. In the upper part of the dust-depressing device there is a built-in damping member, and in the upper cover of the chamber of the basic grinding there are elements of distortion of the fields of the gas-suspension flow made in the form of resonators. The invention provides increased efficiency of grinding.

EFFECT: the invention ensures increased efficiency of grinding.
