Semi-industrial experimental research on the influence of moisture on air dense medium fluidized bed separation

Abstract

This paper conducted a semi-industrial experimental study on the influence of moisture on air heavy medium fluidized bed separation. The research results show that with the increase of coal moisture, the separation accuracy of the separator decreases. When the coal external water is 6.83%, it is difficult to effectively sort the coal; with the increase of the sorting time, the medium moisture will increase slightly; the medium consumption of clean coal and gangue products increases with the increase of the coal external water; when the water exceeds 3%, the media consumption has an almost linear relationship with the external water content; the media with agglomeration or excessive water content is not suitable for direct use as a sorting media and needs to be dried.
