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.
