FIELD: process engineering. ^ SUBSTANCE: invention relates to production of fine powder products. Proposed method exploits plants consisting of one or more pneumatic separators, dust separators, for example, cyclones and/or filters, at least one blower, and pipelines or channels communicating said devices for air and solids transfer. Air relative humidity in pneumatic separator varies from 15% to 35%. Water is sprayed in air inlet channel at 60-115 bar, water drop size making <30 mcm. Prior to spraying, water is heated to 50-90C. Inlet channel sizes are selected to allow air speed to vary from 1 m/s to 3 m/s. Air used for separation is forced via air saturator. ^ EFFECT: higher efficiency of separation, power savings, nonpolluting process. ^ 8 cl, 6 dwg |
