Media wear is much less than an SAG circuit in terms of total volume (balls and liners) or as unit consumption in terms of kg/kWh or kg/t. However, although the volume is less, the wear materials are much more highly finished—in economic terms, a high-volume. lower value media is replaced by a low-volume. higher value media.The aim of the wear study is to develop an accurate roll-wear prediction for hot strip finishing mills, which takes more influential parameters into account. A new model of higher accuracy is presented. This model is based on a large amount of production campaigns. The strategy of the work is described below.

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.Ring, roller, turn plate becomes a grinding chamber of vertical roller mill. The raw material and processing craft of the four kinds wearing parts determine the serve life and performance of whole vertical roller mill. Generally, the long life wear parts need grinding, tempering and regrinding and reprocessing craft.
