Abstract

A method for supplying pre-heated particulate mineral material from a separating cyclone to a cyclone furnace inlet includes receiving the mineral material in a material receiving conduit from a bottom outlet of the separating cyclone. There is a first pressure in the receiving conduit. The mineral material is fluidised in the receiving conduit and flows upwards in an inclined elongated gas-lock valve from a lowermost section of the receiving conduit to an uppermost section of an outlet conduit. The mineral material is supplied from the outlet conduit to the inlet of the cyclone furnace, wherein there is a second pressure that is higher than the first pressure. A fluidisation unit in the gas-lock valve maintains the particulate mineral material in a fluidised state, such that the fluidised particulate mineral material flows due to gravity from the material receiving conduit, upwards through the gas-lock valve and to the outlet conduit.
