DEVICE FOR MECHANICAL ACTIVATION AND CRUSHING OF MATERIALS Russian patent published in 2010 - IPC B02C7/06 B02C13/06 B02C23/06 

FIELD: technological processes.

SUBSTANCE: invention relates to devices for mechanical activation and crushing of materials with various hardness and may be used in power engineering, construction, mining, metallurgical, chemical industry, medicine and other industries in production of high-quality produce, and also for production of finely dispersed multi-component mixtures of various minerals, polymers and powders. Device for mechanical activation and crushing of materials comprises two disk rotors coaxially installed on hollow horizontal shafts with opposite direction of rotation. Rotors are arranged to each other with technological gap, are installed in hollow body, and each has open circular channels on inner surface, which arrange annular crushing chambers together with open circular channels of the second rotor. Crushing chambers are communicated to each other by speed-up channels arranged tangentially with inclination towards rotor rotation, closed by circular labyrinth seals. One of rotors is arranged with closed channels for pressurized supply of ionised gas components into annular crushing chamber or air from horizontal shaft of ioniser communicated to cavity. Inner surface of each annular crushing chamber is arranged as corrugated along its length in the form of transversely arranged circular indents and ledges, which provide for direction of crushed particles motion towards centre of crushing chamber and action of axial oscillations for sticking of crushing chamber walls and clumping of particles to each other.

EFFECT: improved efficiency, reduction of energy intensity and production of high quality product of crushing.
