Abstract: 1,156,592. Detecting particle size distribution photo-electrically. KENNECOTT COPPER CORP. Jan. 19, 1968 [Jan. 19, 1967], No. 3083/68. Heading G1A. In a method of determining particle size distribution in discrete solids, a sample of the discrete solids is introduced into a vessel, through which fluid-flows upwards with reducing velocity as it rises through the vessel, so that the particles seek different levels in the fluid and radiation is passed through the fluid at least one level and measured to detect particles of a size associated with that level. As shown the vessel is made of glass and has three cylindrical sections 15a, 15b and 15c and water entering through a side pipe 24a flows upwardly through the vessel and out through an overflow pipe 18. The vessel is periodically emptied by operation of a valve 25 leading to an outlet pipe 28. After each filling of the vessel a sample of ore taken from a conduit 13 through which it flows is passed through a sample cutter 14 and introduced as at 16 into the top of the vessel. The particles descend under gravity against the flow of water to a position of equilibrium dependent on the particle size. In each of the cylindrical sections 15a and 15b light from an associated source 33 and vertically collimated by an associated slit 34a is passed through the fluid to associated detectors 41, when equilibrium is reached. The detectors which are cadmium sulphide photo-resistors are connected in parallel and the combined output is fed to a pen recorder. The ore in the conduit is slurried ore from a crushing and grinding machine which may be controlled manually or automatically e.g. by feeding back the ore for further processing in accordance with the output. The water is supplied to the side pipe 24a from a constant head apparatus 20 via a visual flowmeter 22. The level of the water can be adjusted by repositioning an outlet pipe 27 and can be set by introducing a reference sample of ore having a known size distribution.
