摘　　要：在离心力场中进行煤炭浮选是一项先进的技术。离心力场强化煤泥的分选效果,提高浮选速度,改善精矿中高灰细泥的夹带现象。离心浮选设备具有占地面积少、节约生产费用等许多优点。但在离心力场中浮选也存在许多被制约的条件,如入浮粒度不能太粗,离心强度不能太大等.本文从理论上研究分析了离心力场浮选技术的先进性和缺陷,以期对研制实用的离心浮选设备有所帮助。Floatation in centrifugal force field is an advanced technique. The separate efficiency of slimes is improved. The floatation speed is increased. The effect of mixed plaster on floatation concentration is reduced. The centrifugal force equipments have a lot of advantages,for example,the size is smaller and the productive costs is reduced etc. But the technology has a number of defects,for example,the article size in floatation system con not be too big and the force strength can not be strong etc. The paper mainly deals with the advantages and defects in theory. It is expected to give a help to the development of the equipment of floatation in centrifugal force field.
