METHOD OF DRYING WET PASTEOUS GRAPHITE Russian patent published in 2016 - IPC F26B3/12 

FIELD: mining.

SUBSTANCE: invention relates to industrial production of powdered graphite concentrate and can be used in production and concentration of graphite ore. Improved method of drying wet pasteous graphite by its supply over a flow of gas-air mixture forming a gas torch into a rotating cylindrical chamber through its front window, displacement and heating with the gas torch with moisture evaporation along the chamber axis, moisture and combustion products discharge into the atmosphere, and the dried graphite - into the systems of screening and packing through the rear window of the chamber and an adjoining graphite catcher.

EFFECT: during the method implementation when wet pasteous graphite is supplied into the chamber it is divided into agglomerates with compressed air jets to form an air-agglomerate mixture, and the air-agglomerate and the gas-air mixtures are introduced into the chamber with cocurrent horizontal slot flows, herewith the gas-air mixture is supplied at a shortage of air for complete combustion of gas, the gas is burnt up with air agglomerating the pasteous graphite, and the air to form the gas-air mixture is taken from the workshop aspiration system.
