ABSTRACT:
A method for industrial production of especially fine powders and mineral powders, where the material to be ground is mixed to a gas-solid matter suspension, which through acceleration nozzles (12) is led at least to two counter jets, which meet in grinding chamber (13) for further grinding of the powders. The ground gas-solid matter suspension is led in its turn by means of working gas at least to two intermediate containers (2a);(2b) in the grinding circulation, in which containers the gas is removed from the mixture and into intermediate container (2) a certain quantity of solid matter is collected, which quantity is returned to be ground and led to the other container (2) and the said quantity is circulated through the grinding process among intermediate containers (2a);(2b) until in some container the quality is established sufficient for removal off the process.
