DISINTEGRATOR Russian patent published in 2016 - IPC B02C13/00 

FIELD: construction.

SUBSTANCE: invention relates to devices for grinding of low-abrasive materials and can be used both in production of construction materials and other industries. Grinding disintegrator comprises rotors located in pairs and equipped with drives 3 and 4. All rotors are located symmetrically in housing 5 and provide for a possibility of rotating the outer rows of striking elements in the direction of the unloading device, which is equidistant from rotational axes of rotors. Two loading devices 6 arranged on rotor pairs axes adjoin housing 5. Disintegrator comprises two spiral branch pipes 12 of variable cross-section located outside the housing. Inlet of each spiral branch pipe 12 is in the plane tangent to curvilinear sections of housing 5 located at the maximum distance from the unloading device, while the output tangentially adjoins loading device 6 of opposite rotors pair.

EFFECT: disintegrator ensures an increase in degree of grinding due to return of coarse material for additional grinding and due to a possibility to mix different materials.
