DISINTEGRATOR Russian patent published in 2016 - IPC B02C13/22 

FIELD: materials.

SUBSTANCE: invention relates to grinders of various materials and can be used in production of construction materials, as well as in other industries. Disintegrator comprises cylindrical housing 1 with axial loading 3 and tangential discharging pipes 2, arranged in cylindrical housing 1 to counter-revolve upper 4 and lower horizontal discs 7 with secured along concentric circles impact elements 5. Each impact element 5 is arranged between impact elements of opposite disc. At output of axial loading pipe 3 at an angle to upper horizontal disc there are scattering pipes 6 bent in a direction, opposite to direction of rotation of upper disc 4. Inclination angle α of scattering pipes to upper horizontal disc 4 is greater than angle of natural slope of crushed material. Lower horizontal disc 7 is attached to lower axial hollow loading pipe 8, inside of which is rigidly fixed screw feeder 11. At output of lower axial hollow loading branch pipe at an angle α to lower horizontal disc there are lower scattering pipes, bent in direction opposite to direction of rotation of lower disc. Inclination angle α of lower scattering pipes to lower horizontal disc is greater than angle of natural slope of crushed material. Lower ends of scattering pipes are located in gaps between impact elements of first inner row, belonging to lower disc. Distance between ends of lower scattering pipes and impact elements of second inner row a > D_max, where D_max is maximum size of particles of crushed material.

EFFECT: disintegrator is characterised by high efficiency of grinding process.
