Separating device for separating mixtures of substances like lime, mica and mineral carbon uses air and gas to cause the mixtures to flow through a shaft with arches and slanted side walls

摘要

Powdery mixtures of substances strike a surface like a rotating drum (RD) (3) and pass in zigzag motion through a shaft. Impact with slanted wall sides (2) isolates lumpy particles and causes flour-type powder like lime (8) to stay bonded to the RD and fine pourable particles (7) like quartz granules are released. The RD brings the mixtures into an electrostatic field (5)/electrode (4).
