METHOD TO LOAD FINE GRAIN SIZED MINERAL.

摘要

In a method to load a fine grain sized mineral inside a reactor pressure-container (1), hot mineral is firstly introduced into a transportation pressure-container (35, 36), wherein it is pressurized by a compressed gas, and is subsequently transported inside the reactor pressure-container (1), through a transportation conduit (5) by the compressed gas. To ensure an advantageous utilization of the reactor pressure-container (1), under an even pressure and to prevent said pressure from being reduced while the mineral is directly loaded, a mineral portion is introduced inside at least an additional transportation pressure-container (35, 36), and is also pressurized thereinside by a compressed gas, the mineral loading operation inside the reactor pressure-container (1) being continuously carried out, and the mineral feeding being alternately performed, first from the first transportation pressure-container , and subsequently from the additional transportation pressure-container (35, 36), wherein the compressed gas is taken from the process gas as a quantitative portion or a component portion of said process gas, and is fedback thereto together with the mineral.
