Comparison of the overall circuit performance in the cement

The vertical roller mill has the obvious advantages of a high yield and low power consumption and is primarily used in large-scale slag grinding lines [32]. However, the relationships among the type of grinding equipment, the product fineness and the application quality have yet to be systematically studied, which affects the accuracy of a(max moisture 20% vs. 3% in ball mill) [15], [16]. • Big feed size The vertical roller mill can grind the material of particle size of 5% of the grinding roller diameter. The feed size is generally 40 to 100 mm and can reach 120 mm in case of large VRM. In turn it simplifies the grinding system [15], [16]. •Review on vertical roller mill in cement industry & its

A cement Vertical Roller Mill modeling based on the number of breakages. Vertical roller mills (VRM) are widely used to grind, dry, and select powders from various materials in the cement, electric power, metallurgical, chemical, and nonmetallic ore industries. For the sectors above, the VRM is a powerful and energy-intensive grinding 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 Analysis and Optimization of Grinding Performance of Vertical Roller
