The global vertical roller mill market is projected to grow at a CAGR of % from 2017 to 2030. The growth of the global vertical roller mill market can be attributed to the increasing demand for cement and minerals in developing countries and the growing awareness of energyefficient technologies among consumers.
The vertical roller mill itself is equipped with a powder concentrator, which can remove fine powder in time, reduce the phenomenon of overgrinding and improve the grinding efficiency. The vertical roller mill is less power consuming. The energy consumption of a vertical roller mill is around 75% of that of a ball mill of the same capacity.

A study conducted by Gerold et al. (2012) showed that VRM was able to grind copper and slag with the energy saving of % and % respectively compared to conventional grinding circuits. Wear rate is another criterion that is needed to be considered. In this context, Erkan et al. (2012) in their study compared the wear rates of rodball ...
roller units and mill housing are not connected, leaving the mill housing free of forces. The mill foundation is designed according to the force transmission, which results in a vibration value due to the grinding process of less than 2mm/s, measured at the roller units. Of course, to absorb the grinding forces and load
The quadropol® concept for coal or pet coke grinding, with adapted table speed and high efficiency separator sepol®, ensures a safety mill operation and serves reliable the kiln burning process. Mombasa Cement Ltd. ordered a QMK² 24/12 with three roller units for the 5,000 tons per day kiln line.
In conclusion, the application of vertical roller mill technology in the cement industry has revolutionized the way cement is produced. VRMs are more energyefficient, ecofriendly, and produce a more consistent product compared to traditional grinding mills. They are also more suitable for use in urban areas due to their lower noise level.
