In this paper, the working principle and structure of low-vibration vertical roller mills and forces of key component were analyzed intelligently. The size of main forces was calculated. A 3D simulation model of the rocker arm-roller system was set up and an intelligence finite element analysis was conducted based on the Ansys Workbench. Cement Mill Noise Level and Attenuation Report Page 2 1. Executive Summary The study was conducted to establish if the noise radiated by two different cement grinding technologies, i.e. a conventional ball mill and a vertical (roller) mill, would be sufficiently attenuated at the boundaries of the proposed sites to adhere to regulations.

DESCRIPTION OF THE INVENTION. The prior art vertical roller mill 10 is completely enclosed within a vertical mill body 11, which serves to encapsulate gas, material, and grinding/separator parts. Mill 10 has a grinding table 12 rotating about a vertical axis supported and rotated by a gearbox 13 which is driven by a conventional motor (not shown). simplifying plant layout. Concrete mill stands replace the traditional steel structures, reducing installation time and costs. Using concrete also means lower mill vibration at the foundation. The high-performing vertical roller mill generates minimal noise during operation due to the lower level of mill vibration.
