The water can wash away the fine particles in time to avoid overgrinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.

duty. In the iron ore industry, most of the machines are found in pellet feed applications. However, there are a few notable examples where HPGRs are used for coarse iron ore grinding in Chile, Mauritania and the USA. The first large scale attempt at applying HPGRs to harder and more abrasive copper and gold ores was in 1996 at Sierrita.

Introduction Hematite and magnetite are the most prominent iron ores. Most of the highgrade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− + mm) and fines (approximately − mm) products.

Several basic assumptions are made in modeling of the grinding process in various types of mills and milling circuits. Most frequently, it is assumed that the mill's content is uniform and thoroughly mixed by the rotation of the mill and the movement of the grinding media [44]. In this case the model is known as a perfectly mixed model.

A special development is the autogenous or semiautogenous mill. Autogenous mills operate without grinding bodies; instead, the coarser part of the ore simply grinds itself and the smaller fractions. To semiautogenous mills (which have become widespread), 5 to 10 percent grinding bodies (usually metal spheres) are added.
