AIR SEPARATOR-GRANULATOR OF COMBINED ACTION Russian patent published in 2019 - IPC B07B7/08 B01J2/28 C22B1/14 

FIELD: technological processes.

SUBSTANCE: invention relates to the technique of separation of fine materials and can be used in various industries of building materials, as well as mining, chemical, energy and other industries. Air separator-granulator of the combined action includes a housing, in the upper part of which a clean gas pipeline is sealed to which the electric drive and the fan are fixed, and located below it are the truncated cones which are included in each other and displaced relative to each other in height, with their large bases facing upwards, the smaller bases of which are angled to the horizontal coinciding with the angle of repose of the material. Upper truncated cone with a smaller base is rigidly fixed on the lower truncated cone that enters into it, forming a groove-shaped channel that passes into the discharge port. Lower truncated cone contains a tangentially located boot inlet. Inside the truncated cones there is an impenetrable receiving cone, with its large base facing upwards, and the smaller base of the receiving cone ends in a discharge nozzle. Receiving cone is installed with adjustable height. Above the upper part of the receiving cone, in the upper part of the body there is a cone-shaped dome with a hole in which the gate valves are located. Under the lower base of the receiving cone there is a device for aerial granulation, containing two receiving distribution plates, two toroidal chambers, a container for a liquid binder, an accelerating tube, which is tangentially connected to the upper toroidal chamber located horizontally, and an opening for unloading material into the lower toroid-shaped chamber, also horizontally disposed and having an opening for unloading, covered by a gate valve, at least three external cyclone-type elements are installed along the outer perimeter of the upper part of the housing.

EFFECT: improving the classification efficiency and reducing energy consumption.
