Abstract: 1387442 Photo-electric detection devices BRITISH TITAN Ltd 12 April 1973 [20 May 1972 (2)] 23849/72 and 23850/72 Heading G1A The size distribution of a powder suspended in a liquid is measured by passing a beam of electromagnetic radiation, e.g. X-rays or gamma rays, through the liquid suspension contained in an annular chamber at the periphery of a disc-like member during rotation of the member, and measuring the absorption or scattering of the beam, the beam having a thickness d in the radial direction of the disc where d/r is not greater than 0.2 in which r is the radial depth of the beam in the liquid from the radial inner surface thereof and where r/R is not greater than 0.1 in which R is the radius from the centre of the disc to the radial inner surface of the liquid. As shown, the apparatus includes the disc 1, an annular wall 2 and a disc 3 forming a chamber in which the liquid is contained, a motor 6 to rotate the disc, a collimator 20 and an adjustable slit 16, 16<SP>1</SP> for directing X-radiation through the liquid and a detector and amplifier 19. The disc is movable relative to the slit by a device 8 having a scale 9. In operation, liquid free of powder is introduced in a known volume into the annular chamber, the disc is rotated, and the disc is moved by the device 8 until the detector detects the interface between the liquid and the inner space of disc 1. The disc is then moved a known distance so that the beam is at the known distance below the liquid interface. The output of the detector is supplied to a counter and to a chart recorder. The liquid is then removed and the chamber is dried, and the same volume of liquid suspension is introduced into the chamber. The intensity of radiation passing through the liquid is immediately measured and then the disc is rotated and the intensity measured and recorded during the sedimentation process. The operation is completed when the counter indicates the same count rate obtained using pure liquid. The particle size distribution can then be calculated using the recordings. The X-ray wavelength is specified to be 1.54 provided by an x-ray tube. Alternatively, the source may be a radioactive isotape, e.g. cobalt, caesium, indium, thulium, or cadmium.
