Quartz is a hard mineral frequently being part in cement raw mixes. Hence it is of interest to correlate its content in the mixture with the wear rates experienced in vertical roller mills (VRM). From the experience of numerous laboratory VRM tests, it is known that the measured wear rates might not correlate with wear rates in full scale VRMs.
