The application of vertical roller mills (VRMs) for ore grinding is a part of the strategies against rising energy consumption (Reichert et al., 2015). The VRM technology was introduced in the mid'90s for grinding clinker and slag by LOESCHE (Schaefer, 2001). Fig. 1 illustrates the grinding parts of a Loesche vertical roller mill.
Vertical roller mills (VRM) have been used extensively for comminuting both cement raw materials and minerals like limestone, clinker, phosphate, manganese, magnesite, feldspar and titanium.

Ball mills are one of the most widely used grinding machines in the mineral processing industry. These machines use grinding media, usually balls, to break down materials into fine powders. Ball mill liners play a crucial role in the operation of a ball mill, ensuring its efficiency and longevity.. What is a Ball Mill Liner? A ball mill liner is a type of material that is placed inside a ball ...
Due to this closed system the design of vertical roller mills is more complex than tumbling mill design. In order to work on that problem, the Institute of Mineral Processing at the Montanuniversitaet Leoben and the company CEMTEC Cement and Mining Technology developed the laboratory scale vertical mill VRM2. In this article published design ...
In cement production, tube mills having multichambers are traditionally used either in open or closed circuit operations. After the introduction of high compression grinding mills (High pressure grinding rolls (HPGR), vertical roller mill (VRM) and Horomill), various circuit configurations have been developed for energy efficient grinding.
