    • The flotation machine includes a flotation cell (1), which comprises a vertical side wall (2) and a bottom (3), and which is upwards open. An air distribution and mixing device (4) is arranged in the vicinity of the bottom for distributing air to the slurry for forming froth and mixing the slurry in the flotation cell. The air distribution and mixing device includes a rotor part (5) that comprises air distribution apertures (6). A drive shaft (7) extends vertically in the flotation cell. The rotor part (5) is attached to the lower end of the drive shaft (7). The drive shaft comprises a hollow interior (8), which constitutes a flow channel for conducting flotation air to the air distribution holes (6) of the rotor part. An electric motor (9) is arranged to rotate the drive shaft (7). The electric motor is supported by a separate supporting framework (10), which is on top of the flotation cell. The electric motor (9) is a permanent magnet motor that comprises a vertical rotor axis (11), the lower end of which is in permanent contact directly with the upper end of the drive shaft (7).
    • 浮选机包括浮选槽(1),其包括垂直侧壁(2)和底部(3),并且向上敞开。 空气分配和混合装置(4)布置在底部附近,用于将空气分配到用于形成泡沫的浆料中并将浆料混合在浮选槽中。 空气分配和混合装置包括包括空气分配孔(6)的转子部分(5)。 驱动轴(7)在浮选槽中垂直延伸。 转子部分(5)安装在驱动轴(7)的下端。 驱动轴包括中空的内部(8),其构成用于将浮选空气引导到转子部分的空气分配孔(6)的流动通道。 电动机(9)布置成使驱动轴(7)旋转。 电动机由独立的支撑框架(10)支撑,该框架位于浮选槽的顶部。 电动机(9)是永磁电动机,其包括垂直转子轴线(11),其下端直接与驱动轴(7)的上端部直接接触。
