PROCEDURE FOR GAS JET DISINTEGRATION OF MATERIAL AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC B03B5/02 

FIELD: machine building.

SUBSTANCE: procedure for jet-acoustic disintegration of material consists in loading source material into a working chamber and in disintegration of material by outflow of gas jet into water medium forming acoustic vibrations. Vibrations together with mechanical collisions of lumps at material movement destroy bonds between clay particles in aggregates and release and suspend particles in water medium. The procedure also consists in material unloading. Before loading into a working chamber source material is mixed with water and is imparted to a circular motion inside the chamber with kinetic energy of gas jet created with a jet-acoustic generator. Gas jet is out-flown into water medium in pulses. A bottom of the working chamber is not even owing to which layers of flow are vertically mixed thus maintaining turbulence of flow and avoiding density de-lamination of constituents with different values of density. The procedure is implemented by means of the device consisting of the working chamber, of loading and unloading ports and of a device for supply of gas jet. The working chamber corresponds to a cylinder with a bottom the initial section of which rises from the line of loading and then declines. The loading port is located on a vertical wall of an upper part of the working chamber; while the unloading port is positioned on the same wall in a lower part of the chamber at the end of a decline. A loading zone is separated from an unloading zone with a partition with an orifice at a level of the device for supply of gas jet corresponding to a jet-acoustic generator which is mounted on a fulcrum bearing secured on a vertical telescopic rod and facilitating transfer along height of the chamber and supply of jet along its side wall.

EFFECT: raised efficiency of preparation of hard flushed material to refining.
