METHOD AND APPARATUS FOR X-RAY DIFFRACTION ANALYSES

摘要

A method and apparatus for continuously presenting a sample from a stream of particulate material which contains crystalline substances and effectively continuously analysing the sample by X-ray diffraction. An extracted sample flow (23-22-24) is fed onto a continuously moving carrier (10-12) and its surface smoothed and flattened (25-26-30-32) for X-ray diffraction patterns to be detected (34-36) and analysed (38) to provide a compositional analysis for the crystalline substances. The sample (24) is continuously removed (40) from the carrier (10) prior to further sample being fed onto the carrier. The invention is particularly applicable for phase composition analysis of cement and cement clinker and provides and effectively continuous analysis substantially in real time in contrast to prior art laboratory analysis of discrete samples.
