DEVICE FOR THERMAL TREATMENT OF BULK MATERIALS Russian patent published in 2015 - IPC F27B1/02 F27D7/04 

FIELD: technological processes.

SUBSTANCE: invention relates to building equipment, in particular, to vertical ovens and may be used in the building field for thermal treatment of finely dispersed (dust-like) bulk materials, for instance, lime, cement, metakaolin, periclase etc. The device for thermal treatment of bulk materials includes a thermal treatment chamber where bulk material particles move spiralwise downwards along the chamber walls as a result of gravity action force, aerodynamic action force and centrifugal force. The rotor in the chamber provides for rotational movement of gas and bulk material captured by gas around the rotor. The gas removal device usage in the chamber with bulk material separation leads to the material fine particles losses exclusion.

EFFECT: invention usage allows to enhance performance, improve the treated material quality and ensure release of gas generated during thermal treatment from the chamber.
