Cement fineness is an important quality parameter in the cement grinding process. However, very few studies have been done for soft sensing of cement fineness in the grinding process. Moreover, most of the grinding process modeling approaches have been reported for ball mills and rarely any modeling of vertical roller mill is available.

Abstract: Vertical roller mills (VRM) for cement grinding have now been in operation in North America for almost 20 years. Many opportunities exist to upgrade the older vertical mills with the latest technologies to improve efficiency. Recently a southern California cement plant upgraded their vertical cement mill circuit, one of the first installed in the US, …

The purpose of the mill system is to provide a fineness to the product that will result in the required reactivity and consequently the strength producing potential of the product – the cement. The fineness of cement is usually monitored by measuring the specific surface area (Blaine) or a sieve residue of the product.
