Modeling Based on the Extreme Learning Machine for Raw Cement Mill
Vertical cement mill (vertical mill) is a machine that plays an important role in the raw meal production process of the new-type dry cement, and it is a set breakage, drying, grinding, transport in one [ 1 ]. Raw material grinding process is a vital and energy consumption link in the cement production. According to statistics, raw materialThe energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended. 2.5.Energy-Efficient Technologies in Cement Grinding IntechOpen

Analysis and Optimization of Grinding Performance of Vertical
This work concentrates on the energy consumption and grinding energy efficiency of a laboratory vertical roller mill (VRM) under various operating parameters. For design of experiments (DOE), the response surface method (RSM) was employed with the VRM experiments to systematically investigate the influence of operating parameters on A study conducted by Gerold et al. (2012) showed that VRM was able to grind copper and slag with the energy saving of 22.9% and 34.4% respectively compared to conventional grinding circuits. Wear rate is another criterion that is needed to be considered. In this context, Erkan et al.
