<p>An alignment measuring system is used in determining the location of the rotational centre line of a long, cylindrical body having a number of support bearings spaced along its length, during the rotation of the body. The method particularly lends itself to the re-alignment of hot kilns, during their operation, without requiring shut down and the consequent disruption and loss of product. The system utilizes a base line or datum on each side of the kiln for locating the measuring instrument. The distance measuring instrument is a radiant beam instrument such as a diode laser providing an electronic readout, to enable accurate determination of the distance of the outer surface of the kiln shell from the instrument, and hence the location of the rotational centre relative to the established baseline datum, for the longitudinal station being measured. A series of lateral centre line determinations thus made along the length of a kiln, and including a like determination of the height of the centre line at each measuring station, permits adjustment to selected ones of the kiln support bearings to align the rotational centre line along the length of the kiln, including the correction of centre line elevations.</p> |
