Abstract: A flotation machine includes a stator positioned in a tank adjacent a rotor. The stator has a plurality of vanes. Each of the vanes has a plurality of slots formed therein. Each of the slots has a shape that is elongated in a direction along the width of the vane in which the slot is formed. Each of the vanes is spaced apart from the other vanes to which that vane is adjacent. The vanes are positioned in series adjacent a periphery of the stator to define a central opening within the stator that is sized such that the rotor of a flotation machine may be positioned therein. The stator may be retrofitted onto a prior flotation machine installation. For instance, a stator may be offered for sale and then installed onto a flotation machine. A previous stator may be removed before the installation of the new stator.

Abstract translation: 浮选机包括定位在与转子相邻的罐中的定子。 定子具有多个叶片。 每个叶片具有形成在其中的多个槽。 每个槽具有沿着形成有槽的叶片的宽度的方向上延伸的形状。 每个叶片与叶片相邻的其它叶片间隔开。 叶片被定位成与定子的周边相邻地定位，以限定定子内的中心开口，其尺寸使得浮选机的转子可以位于其中。 定子可以改装到先前的浮选机装置上。 例如，定子可以被提供出售，然后安装在浮选机上。 可以在安装新定子之前去除先前的定子。
