Abstract: A sprinkler system includes a fitting and a sprinkler. The fitting includes a hose and at least one adapter coupled with the hose. The at least one adapter includes a first engagement member and a receiver adjacent to the first engagement member. The receiver has a greater inner diameter than the first engagement member. The sprinkler includes a body, at least one flange extending from the body, and a second engagement member extending from the at least one flange.

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: At least one froth receiving device may be positioned in a slurry retained in a tank of a flotation cell of a flotation machine. Each of the froth receiving devices may be positioned adjacent to froth formed in the slurry by being positioned in the tank at a height that positions the froth receiving device in the froth or near the froth. Each froth receiving device may receive froth to extract the froth from the tank. In some embodiments, the extracted froth may be sent to at least one particle separation device so at least a portion of solid material in the froth is separated from liquid of the froth. The separated solid material may be moved to another machine for further processing for recovering the desirable material while any remaining solid material and liquid may be sent to another device for being utilized in further material processing.

Abstract: Hydrocyclone and method for separating and classifying solids in which a slurry is introduced into the cylindrical inlet section of the separation chamber of the hydrocyclone so that the slurry rotates about the axis of the chamber, then passes through a first conically tapered section of the separation chamber, and thereafter through a second conically tapered section which has a smaller cone angle than the first conically tapered section. The finer solids are removed through an overflow outlet toward the upper end of the separation chamber, and the coarser solids are removed through an underflow outlet toward the lower end of the chamber.

Abstract: An ultrasonic sensor is mounted on the splash skirt at the underflow outlet of a hydrocyclone to detect a change in the underflow discharge from the normal conical shape in which the discharge impacts upon the splash skirt to a more cylindrical shape associated with roping.
