| 摘要 |
The invention relates to a method for mixing at least two fine-grained solids in a gas-tight sealed container with a given container volume. Pressure variation in the gas in the container are generated by means of periodic mechanical changes to the gas volume, until the fine-grained particles are brought to oscillate in resonance with the pressure variation. The device comprises an arrangement for generation of a periodic axial movement, comprising a gas-tight axially elastic element, which can be bolted in a gas-tight manner to the container, such that the axially-elastic element contracts on expansion of the container volume and expands on contraction thereof. |
