HYDROMECHANICAL PROCESSING ROTOR APPARATUS Russian patent published in 2011 - IPC B01F7/26 

FIELD: process engineering.

SUBSTANCE: invention relates to grinding and may be used in dispersion of heterogeneous suspensions to make crystalline round particles to be used in composite compounds. Apparatus comprises housing accommodating stator and radially wavy surface rotor. Stator disk is rigidly secured to housing and has its radially wavy surface facing rotor while rotor disk is rigidly secured to housing and has its radially wavy surface facing stator. Stator and rotor surface wave angle makes 5 to 25 degrees while gap between stator and rotor makes 5 to 15 mm. Suspension flows from mixing apparatus into rotor apparatus suction branch pipe, between rotor and stator and, via outlet branch pipe, flows back into apparatus. Suspension may be aqueous and in organic solvent. Rotor rpm, rotor and stator diameters are selected to ensure suspension turbulent flow between rotor and stator and Reynolds number exceeding 14000.

EFFECT: round particle crystalline substances.
