...A band distribution according to the specific gravity and particle size of the mineral particles is thus formed on the plate, and these particles are separated and collected by falling at different positions on the edge of the plate. A spiral concentrator is a wet specific gravity separator in the shape of a spiral trough. As the ore pulp supplied from the top of a spiral trough like that shown in Figure 2-a flows down the trough, the action of the water, gravity, and centrifugal force causes the high specific gravity fine particles to gather on the inside of the spiral, while the low specific gravity coarse particles segregate to the outside of the spiral. ... *Some of the terminology explanations that mention "spiral concentrator" are listed below.

…こうして盤上には鉱物粒子の比重と粒度にしたがう帯状分布が形成され,これらの粒子は盤の端の異なった位置で落下することにより,分離・回収される。 〈スパイラル選別機spiral concentrator〉はらせん状のといの形をした湿式比重選別機である。図2‐aのようならせん状のといの上部から供給された鉱石パルプはといを流下する過程で水の作用力,重力および遠心力により,高比重で細かな粒子はらせんの内側に集まり,低比重で粗い粒子はらせんの外側に偏析する。… ※「spiral concentrator」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
