TECHNOLOGICAL COMPLEX FOR PRODUCTION OF METAL POWDERS OF FLAKY FORM Russian patent published in 2020 - IPC B22F9/04 

FIELD: metallurgy.

SUBSTANCE: invention relates to powder metallurgy, particularly, to production of powder materials, and can be used, in particular, for production of flaked copper powder used in chemical purification of titanium chloride from impurities, as well as for production of paints. Technological complex for production of metal powders of flake form contains feeder for granules loading, feeder for protective grease loading, mill with grinding balls, made with possibility of rotation by means of electric drive with constant frequency around its horizontal axis, unit for air supply to inner cavity of mill, aspiration unit, powder unloading unit, system of pipelines connecting said units into single aerodynamic ring consisting of parallel operating main and auxiliary circuits for air circulation and transfer of produced product, wherein pipeline connecting suction part of air supply unit to mill and aspiration unit at outlet, is configured to control ambient air suction, and pipeline connecting air supply unit discharge part and mill is equipped with shutter for changing amount of air supplied to mill inner cavity, at that, mill frequency drive incorporates infinitely variable speed control device.

EFFECT: invention is aimed at reduction of quantity and assortment of assembly units as a part of complex, increase of finished product share, increase of efficiency of technological complex, production of flaked powder with particles having larger ratio of their side surface area to volume.
