Original Abstract

This paper deals with a possibility of application of an objective colour determination in the materials grinding industry. The work presents flame atomic absorption spectrometry (Flame AAS) data as a reference method and CIELAB objective colour measurement from which the whiteness factor was used for an experiment on determination of iron content in limestone and corundum ground stock. In order to have substantial colour change in the samples comparing to feedstock, attritor-type mill grinding process with steel grinding bodies and duration up to 21 hours was used for samples preparation. Limestone and corundum were chosen as materials for the experiment for their diverse hardness and abrasiveness in the milling process. It is concluded that, when properly calibrated, the method could be used in grinding plants for very fast tentative inspections of the ground material.
