The process audit is an analysis for the operation of an equipment, to establish its performance and to make proposals for measures to increase production, decrease consumption and improve product quality. The objective of the process audit is to establish the actual state of operation for the cement grinding plant (the degree of loading with grinding bodies, the air speed in the mill, the granulation of the material at the entrance and the exit, the wear of the shields, energy consumption) and is the basis for proposing measures for optimization. The audit from a grinding plant is carried out in the following situations: upon commissioning (to record the initial condition of the equipment) after modernization/modifications of the equipment in the composition of the grinding plant whenever there are deviations from the expected performance as a routine test, at least once a year, to appreciate the real condition of the equipment. The paper presents some determinations made at a cement mill from a Romanian cement factory, the sampling method to carry out analyses and recommendations for improving production.
