FIELD: process engineering. ^ SUBSTANCE: invention relates to device intended for mixing heterogeneous and homogeneous systems and may be used in chemical and food industries etc. Disperser comprises housing with feed and discharge branch pipes that accommodate aligned perforated rotor and stator disks. Each hole of rotor and stator disks represents a disk segment truncated by two concentric circles. Area of aforesaid holes and their arrangement obey the claimed set of equations. ^ EFFECT: higher efficiency of mixing heterogeneous and homogeneous systems "fluid-solid particles", "fluid-fluid". ^ 2 dwg
