INSTALLATION FOR PROCESSING OF MATERIALS Russian patent published in 2005 - IPC

FIELD: fluoride methods of processing of titanium-containing raw materials.

SUBSTANCE: the invention is pertaining to the equipment for materials processing and the fluoride methods of processing of titanium-containing raw materials, for example, ilmenite concentrates. The installation for processing of materials contains a reactor made in the form of a cylindrical body, a means of stirring of reactive components, a heating unit located outside a cavity of the reactor, a loading and an unloading units. At that the means of stirring of the reactive components is made in the form of the rotary drive of the body of the reactor. The installation is supplied with an additional reactor made in the form of a cylindrical body, supplied with a rotary drive, a loading unit and an unloading unit and a heating unit. The internal surface of the main reactor is made out magnesium, and such a surface of the additional reactor - out of silicon oxide. The unloading unit of the main reactor is hermetically coupled with the loading unit of the additional reactor. Both reactors are supplied with the gas outlet line branch pipes and the steam conduits for the superheated steam feeding in. The invention improves reliability and service capability of the installation in operations with usage of a highly aggressive fluoride-containing materials, ensures the high efficiency of the process and allows to reach the purity of titanium dioxide up to 100 %.

EFFECT: the invention ensures improved reliability and service capability of the installation in operations with usage of a highly aggressive fluoride-containing materials, the high efficiency of the process and a possibility to reach the purity of titanium dioxide up to 100 %.
