FIELD: material processing.
SUBSTANCE: invention relates to the production of powder materials, namely to copper powder of a scaly shape, used in chemical purification and for production of paints. The complex contains a supplier for loading of granules, a supplier for loading of protective lubricant for granules, a mill with milling balls, a centrifugal fan, a pumping pipeline for air supply to an inner cavity of the mill from the centrifugal fan, equipped with an adjustable flap, an aspiration unit, a powder unloading unit, and a system of pipelines connecting listed units to a single aerodynamic ring consisting of parallel operating main and auxiliary contours for air circulation and transfer of a produced product. At the same time, its is equipped with an exhaust fan for direction of incoming surrounding air contaminated with fine dust-like particles for further purification and an exhaust probe connected to it by means of the pipeline, installed above the centrifugal fan unit and both flaps. The aspiration unit contains a primary purification cyclone and a secondary purification cyclone connected in series with pipelines, each of which communicates with a corresponding receiving hopper for collection of produced powder.
EFFECT: regulation of a fraction composition of produced powder and removal of fine dust-like particles of produced powder coming to an air medium.
