PROCESS LINE FOR MECHANICAL ACTIVATION AND CRUSHING OF MATERIALS Russian patent published in 2010 - IPC B02C23/06 B02C7/00 B02C13/06 

FIELD: technological processes.

SUBSTANCE: invention is related to equipment for fine and ultrafine crushing of materials and may be used in various industries, for instance construction industry, food, medicine, chemical, mining and other industries. Process line for mechanical activation and crushing of materials comprises device for mechanical activation and crushing of materials, system of classifiers with a fine filter for gas components or air connected to them. Filters are connected by means of product line to cavity of body of device for mechanical activation and crushing of materials. Ioniser for supply of ionised gas components or air for recombination with charged particles is connected to cavity of device for mechanical activation and crushing of materials and to reservoir of gas components supply. Device for mechanical activation and crushing of materials comprises two disk rotors coaxially installed on hollow horizontal shafts with opposite direction of rotation, which are arranged to each other with a technological clearance and are installed in hollow body. Each rotor has open annular channels on inner surface, which form annular crushing chambers together with open annular channels of the second rotor, and the chambers are connected to each other by means of speed up channels tangentially arranged with inclination towards rotor rotation, which are closed by annular labyrinth seals. One of rotors is arranged with closed channels for pressurised 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 to prevent sticking of crushing chamber walls and clumping of particles to each other.

EFFECT: increased efficiency of mechanical activation and crushing and reduced energy intensity and metal intensity and improvement of crushing product.
