摘要 |
The invention refers to an ion particle classifier and a method for classifying coarse solid particles from an air suspension of micronized particles, said ion particle classifier comprising a housing surrounding an electrically conductive, cylindrical inner layer, acting as a first electrode, and a centrally positioned rod with a number of radially directed lips, acting as a second electrode, said electrodes being electrically insulated from said housing and coupled to a high voltage current source, an inlet pipe for said air suspension of micronized particles to be classified terminates at a one end of said first electrode and an outlet pipe for an air suspension of classified line particles is mounted close to the opposed and of said first electrode, one end of said is provided with discharge means for a fraction of classified coarse particles of said air suspension, said classifier further being provided with a rinsing air input entering said classifier at one of its ends. |
